Parachute system MCS 350 6. Multico parachute system. "Centaur" on the platform

Brand new topic

On May 20, 1983, a decree of the Central Committee of the CPSU and the Council of Ministers of the USSR No. 451-159 "On the conduct of experimental design work on the creation of a combat car of the landing of the 1990s was published. And the means of landing. " OKR on the martial machine of the landing received the Bakhcha cipher, and by means of landing - "Bakhch-SD".

When developing a new airborne airborne combat vehicle and the means of landing, the scale of the tasks that were set up to the Soviet Airborns in case of war, and the complicated conditions for conducting airborne operations were taken into account. The potential opponent, of course, took into account the role assigned to the Airborne Forces and the possibility of mass parachute landing In my rear of personnel and military equipment. In the course of the teachings of the Armed Forces of NATO countries, the issues of combating aerial landings were practically worked out, and assured the landings by the battalion and above. In the UK, for example, in September 1985 held the teachings of "Brave Defender" with practical development of tasks to combat aerial landing throughout the country. In the American charters, it was emphasized that the commanders of all degrees when planning a combat operation should solve the issues of the protection and defense of the rear of their troops. Intelligence means of intelligence were improved, low and long-distance detection and alerts were deployed, the air defense system was attracted to the fight against air deposits - from individual compounds to the scale of host theater.

To combat landed landings in addition to the protection forces of objects and bases in the rear areas of the troops, battalion, regimental, brigade movable tactical groups were formed from the composition of armored, mechanized and aeromobile parts. Among the fighting measures were envisaged: shelling of military transport aircraft and landing during landing, the attack of the enemy landed the opponent with the mobile tactical group with the support of tactical and army aviation, trunks and reactive artillery, using the initial inorganization of the landing, with the aim of either destroy, or to forces. The emergence of intelligence and impact complexes increased the possibilities of defeating the landing in the landing area.

A comprehensive solution to the problems of reducing the vulnerability of a parachute paratrooper, including the increase in the suddenness and secretion of the landing, an increase in the number of equipment and personnel packed by one echelon, and targeting accuracy, reducing the time of landing and time between landing and the beginning of the pavement of the landing.

The main requirement for a family of airborne airborne aircraft, was landing from the military transport aircraft of the IL-76 (IL-76M) and the An-22 combat vehicles with a full combat kit and refueling, as well as with combat calculation (two crew and five people Man of the landing) placed inside the car. At the same time, the IL-76 had to lift up to two cars with targeting facilities, IL-76M - up to three, An-22 - to four. The landing was planned to produce on land (including high-mountainous sites) and water (with excitement to 2 points). Means of landing were to guarantee a decrease in the minimum permissible height of landing, the minimum possible ratio of their mass to the mass of the pavement of the cargo (combat vehicle with ammunition and calculation), use in various climatic and weather conditions. The probability of conducting an airborne operation after the strikes of the opponent and the dismissal of roads and a number of airfields required to provide the possibility of combat vehicles with a long march to carry out a long march to the airfields of loading with overcoming water obstacles.

On November 30, 1983, the management of orders and supply of aircraft equipment and armament of the Air Force issued the Moscow aggregate plant "Universal" coordinated with the Ministry of Aviation Industry Tactical and Taxation No. 1998 on the development of free tutoring for new BMD. Development of targeting funds on the topic "Bakhch-SD" began under the leadership of the chief designer and the responsible head of the Universal Plant A.I. Balvanov and deputy chief designer P.R. Shevchuk.

In 1984, Universal issued automatic devices (NII AU). Technical task No. 14030 on the development of a parachute system. Work in the research institute AU was headed by director of the institute O.V. Ryshev and deputy director B.N. Skulanov. The design of landing facilities was carried out, of course, in close cooperation with the team of developers of the VGTZ headed by the chief designer A.V. Shabalin and deputy chief designer V.A. Trishkin.

If the BMD-1 base family made it possible to create each next set of targeting facilities based on previously developed samples with a high degree of unification, now it could not be about continuity on nodes and aggregates of speech. Tactical and technical task on " matter The 70s of the 90s "(received the designation" Object 950 ", in production -" Product 950 ") intended a qualitative improvement of its characteristics compared with BMD-1 and BMD-2 and a corresponding increase in dimensions and mass. The planned mass of the new BMD (12.5 T) more than 1.5 times higher than the mass of the BMD-1 family of the BTR-D. Combined with the need to land the entire calculation inside the car with very hard restrictions on the mass of the means of landing agents, it forced to create a new complex. Of course, a rich supply of technical solutions previously found by the station wagon and Research Institute of AU was used during other works, but the design should have been new. In fact, it took a full range of research and development work.

Taking into account the novelty of the task, the Customer agreed that final choice concept Tentition will be made at the stage of protection of the technical project.

Of the two main schemes for the farewell towing facilities used for the BMD-1 - BTR-D (parachute or parachute-reactive system), a multi-pop parachute has been chosen, which ensures greater reliability, which was paramount taking into account the calculation towing. Placing the calculation on universal seats Instead of special amortized chairs, it required the developers to ensure vertical overload when landing not more than 15 g. A multi-power system in combination with energy-intensive shock absorbers could provide it. Therefore, the variant of the parachute-reactive system at the stage of the technical project was not considered.

In December 1985, a meeting of representatives of the customer and industry was held at the Universal Plant on the approval of the technical appearance of the Bakhch-SD funds. The chairman of the meeting was the Army Army Commander, General Army D.S. Sukhorukov, Deputy Commander-General General Lieutenant N.N. Guskov, from the customer - G.I. Cashnya, from the factory "Universal" - N.F. Shirokov, replaced by A.I. Avivalova as a head of the head and chief designer of the plant, from Research Institute AU - Director of the Institute O.V. Ryshev and the head of his Feodosi branch P.M. Nikolaev, from GC Research Institute of the Air Force - Head of the Department A.F. Shukayev.

The meeting discussed three options for free parachute facilities:
- the option of the Feodosi branch of the NII AU represented P.M. Nikolaev. It was, in fact, upgrading the means of landing Type PBS-915 "Shelf" with self-filled aircraft;
- option "Universal" with self-filled air depreciation "Kid". Reported Lead Designer Ya.R. Grinspan;
- Variant of the plant "Universal" with air absorption of forced filling with overpressure inside 0.005 kg / cm2. According to him reported the chief designer N.F. Shirokov.

As a result of a comprehensive study, it was decided to create a third-option targeting funds, providing greater energy intensity of depreciation and smaller overload on the machine housing and placement places for landing. Development received the factory cipher "4p248", the customer assigned to her "PBS-950" cipher.

Designing the means of landing 4P248 (for brevity, called another "System 4P248") was conducted in the 9th department of the Universal Plant under the guidance of the head of the department G.V. Petxus, Chief of Brigade Yu.N. Korovochka and leading engineer V.V. Zhrabrovsky. Calculations were performed by the department headed by S.S. Filler; Tests of landing facilities at the factory were led by the heads of test departments P.V. Goncharov and S.F. Thunder.

The main problems that the developer team had to be decided to decide again, the creation can be attributed:
- the new installation-depreciation device (skis with shock absorbers and the central node), which would provide the loading of the cutting BMD to the plane, fastening it in the aircraft cargo cabin on the rolling equipment, the safe output of the cargo cabin during landing and automatic inclusion to the work of parachute and depreciation systems. A air shock absorber of forced filling 4P248-1503 was designed;
- aggregate intended for forced filling shock absorbers atmospheric air In the volume that ensures the quinetic energy of the cargo during the landing. The unit was named the "block of superior" and received the factory cipher "4P248-6501";
- multi-polar parachute system that would ensure the saved landing and the Object 950 with a full combat calculation. The development of the Parachute system of the ISS-350-12 was carried out in the Research Institute of AU under the leadership of the Deputy Director B.N. Skulanova and Chief of Sector L.N. Chernyshev;
- Equipment allowing BMD with installed towards landing means to make a march to 500 km with overcoming water obstacles;
- electrical equipment placed inside the "object 950" for the issuance of the crew members of the lighting information on the stages of the direction of landing process, as well as to control the accelerated riming means of landing after landing.

The solution adopted at the meeting mentioned did not exceed the search for other possible embodiments of the depreciation device. There was among them and the principle of the airbag. Based on the decision of the State Commission, the SMSR of the USSR on military-industrial issues of October 31, 1986, the department "Universal" was issued a technical task for research work "Investigation of the possibility of creating means of landing equipment and cargo using the principle of an airbag". "Universal", in turn, in 1987 issued the task of the Ufa Aviation Institute. Sergo Ordzhonikidze (WAI), who had previously conducted a similar study within the framework of the "PRED". The newly open Nir received the cipher "blowing-1" and was fulfilled in full.

In the course of this Nir, the landing of the "object 915" (BMD-1) was studied, but it was assumed to use the same principle for more severe objects. The shock absorption device was an inflatable "skirt" at the bottom of the bottom of the battle car, which during the reduction was discharged with pyrotechnic gas generators. Forced air force under the "skirt" was not made: it was assumed that when landeding the machine, due to its inertia, it will compress air in a volume limited by the "skirt", spending on this considerable part of its kinetic energy. Effectively operate such a system could only in ideal conditions and on the perfectly level platform. In addition, the proposed WAI depreciation system provided for the use of expensive rubberized TSM tissue, was complex in preparation for use. Yes, and this work was completed when the funds 4p248 had already passed the stage of government tests. The final report on the NIR, approved by the supervisor leader in December 1988, recognized its results useful, but read: "Using the principle of a gas-air cushion in the planting device on the IP" PRED "and NIR" PREFERED- 1 "for the development of landing systems is inappropriate .

Within the framework of the work on the topic "Bakhch-SD", other NIRs were opened. The composition of the previously developed facilitating facilities for the BMD-1, BMD-2 and BTR-D - experienced ZP170, serial PBS-915 (925) were included in the wind guidrop orientation systems before landing. Relief with their help of the landing facility at the steps of the parachute descent of the longitudinal axis in the direction of the wind demolition allowed to ensure a safe landing at wind speeds in the surface layer to 15 m / s and thereby expand the range of weather conditions of parachute paratroopers. However, the mechanical handrope in the type used in PBS-915 (925), which effectively operated at a wind speed of 10-15 m / s, when it decreases to 8-9 m / s, it simply did not have time to work: with a decrease in the object, Gaidrop's slack was formed by the object. And he did not have time to stretch and deploy an object before landing.

Nii Ay together with the Moscow Aviation Institute. Sergo Ordzhonikidze was developing a solid fuel orientation system (NIR "Air"). The principle of its action was to turn a packed object using a rivesed jet jet engine with a solid fuel gas generator, included and the system turned off automatic control. Data on the height of landing and the estimated direction of the wind demolition of the route of the packed car received prior to the start of targeting from the navigator of the aircraft and introduced into the automatic control system. The latter ensured the orientation of the object in the process of decline and its stabilization until the landing.

The orientation system was tested with a joint landing complex (CSD) and with a BMD-1 layout, a calculation was made for the means of landing the "Object 68m" combat vehicle ("Bass") and "Object 950" ("Bakhch"). The prospect of the system for use in the Airborne Forces, specialists of the 3rd Central Committee of the Ministry of Defense were noted. The Nir was completed in 1984, it issued a report, but did not receive further development - mainly due to the lack of the possibility of accurately determining the direction and speed of the wind in the ground in the area of \u200b\u200blanding site. In the end, from use in 4P248 any orientation system refused. The calculation was made that two air shock absorber in the process of exiting air after landing form shafts on the sides of the cargo, which will prevent overturning due to lateral demolition.

It is appropriate to remember research work According to the choice of materials for the depreciation of parachute platforms and containers, conducted abroad (primarily in the United States) in the 1960s. Foams, kraft fiber, cellular metal structures have been investigated. The most favorable characteristics were metallic (especially aluminum) cells, but they were expensive. Meanwhile, at that time, air depreciation was already used on American and British parachute platforms of medium and large loading capacity. Its characteristics were quite satisfied with customers, but later the Americans abandoned air depreciation, referring to the difficulties of providing stability and prevent the platform overline after landing.

BMD-s ("Object 950")

The Parachute system of the ISS-350-12 was designed by AU based on a block with a parachute of 350 m2, unified with already accepted PBS-915 systems (-916, -925, P-7 platform), and with the system being developed at the same time ISS-350-10 for the means of landing P-211 boats "Gagara".

Nir, conducted in the early 1980s, showed that the most effective way to reduce the minimum height of cargo landing is associated with the refusal of the main parachutes of a large cutting area (as in ISS-5-128M systems, ISS-5-128R and ICS-1400 ) and the transition to "bundles" (or "packages") of an amarrone major parachutes of a small area. The experience of creating an ISS-350-9 system with blocks of the main parachutes of 350 m2 confirmed this conclusion. The possibility of development appeared multicoral systems According to the "modular" scheme: with an increase in the mass of landing load, the number of basic parachute blocks simply increased. Note that in parallel with the ISS-350-9, the ISS-175-8 system has appeared with a double area of \u200b\u200bthe main parachute, which was intended to replace the single-oiled system in parachute reactors of the PRSM-915 (925) - with the same purpose to reduce the minimum tenting height. .

"OBJECT 950" with targeting 4P248 facility in landing position

In both systems, for the first time in the practice of parachute construction, a method for increasing the uniform loading and improving the characteristics of the fillerness of multicoral systems through the use of low-rise brake parachutes and an additional exhaust parachute was used. Brake parachutes were introduced earlier than the basic and reduced the rate of reducing the landing object to the level, providing acceptable aerodynamic loads of each of the main parachutes during their disclosure and filling. The connection of each of the domes of the main parachute with an additional exhaust parachute (Fiberboard) by a single link led to the fact that the Fiberboard, as it were, "automatically regulated" the process of filling the domes. In the disclosure of the main domes, the "leader" was inevitably formed - the dome, which was revealed before the rest and received a significant burden. The effort from DVP could have somewhat "pretty" such a dome and not to give it to completely reveal too early. Ultimately, this was to ensure the uniform loading of the entire parachute system during disclosure and improve the characteristics of its filling. In the PBS-915 system with nine-football ISS-350-9, it made it possible to reduce the minimum height of landing to 300 m at a maximum height of 1500 m and the range of flight speeds of the aircraft for the device (for the IL-76 aircraft) from 260 to 400 km / h. This high-speed range should be noted, it is still not surpassed in any domestic, nor in foreign practice of parachute cargo towing goods weighing up to 9.5 tons.

The same minimum setting height of 300 meters was laid in the tactical and technical task for the development of the Bakhch-SD mediation, it was assumed to "work out the question of reducing the height of landing to 150-200 m." Maximum height The landing was set in 1500 m above the platform, the height of the site above the sea level - up to 2500 m, the flight rate for the instrument in landing was to lie within 300-380 km / h for the IL-76 aircraft (IL-76M) and 320-380 km / h - for An-22.

The 4P248 funds were introduced by the "Universal" developed by the plant "Universal" a new automatic unscrewing P232 with a unlocking clockwork. Moreover, it was created in the development of autotype 2p131 from the parachute platform P-16.

Interesting production and technological requirements of TTZ: "The design of targeting facilities should take into account the technology of serial manufacturers and the most advanced methods of manufacturing parts (casting, stamping, pressing) and allow the possibility of making parts on CNC machines ... Raw materials, materials and purchased products must be domestic production" Design documentation Litera T (stage of a technical project) For the means of landing 4P248-0000, already in 1985. In the same year, the first three copies of the BMD "Object 950" ("Bakhcha") were the factory tests and government tests of the Parachute system of the ISS-350 took place. -nine.

"Object 950" with Means of landing 4P248, loaded into the IL-76 aircraft

BMD "Object 950" with Means of landing 4p248 after landing

For preliminary tests 4P248 Universal factory and Research Institute AU in 1985-1986. Prepared experienced samples of landing agents, as well as dimensional mass layouts of the "object 950". At the same time, it was taken into account that the mass of the product presented in the state testing in 1986 exceeded the planned -12.9 ton instead of the initially defined 12.5 tons (subsequently, the new BMD still "sank"). Funds 4p248 at this time appeared under the changed cipher "Bakhch-PDS", i.e. "Parachute-landing agents."

Preliminary terrestrial tests 4p248 held from September 1985 to July 1987. During these tests, 15 cooked discharges were carried out, including physiological experiments, as well as dropping into an aqueous surface - using lifting crane (in 1986). It was determined that "... Air shock absorbers 4p248-1503-0 with a preliminary superchard chambers provide a landing of the product" 950 "on a parachute system at a vertical speed of up to 9.5 m / s with overloads on board the product not more than 14 units, and universal chairs in the parachute relief position along the x axis "not more than 10.6, along the axis of" no more than 8.8 units and allow one-time application; Universal chairs, taking into account the implementation of measures with the staffing of the depreciation funds, provide member of the crew of the landing conditions ... Means of landing 4p248-0000 When resetting water, provide a parachute system for a parachute system at a vertical speed of up to 9.8 m / s with overloads on board the product more than 8.5; The overloaded overloads do not exceed the maximum permissible, regulated by medical and technical requirements for these objects. "

Means of landing 4p248 after scattering (skis, shock absorbers, central node; well visible the link of the suspension system)

True, the membranes did not work when driven exhaust valvesthat strongly worsened stability even on smooth surface. Modeling on a wind demolition copper at a speed of up to 12 m / s. During landing to land, it did not give tipping. During flight tests, two layouts were dropped and one real "object 950" with 4p248-0000 facilities from the IL-76MD aircraft by single, series and the ZUCH method at the flight speeds of 300-380 km / h. Preliminary flight tests with discharge from the An-22 aircraft were held only in 1988.

Although, in general, according to the report on the preliminary tests of September 30, 1987, "The means of landing" 950 "4P248-0000 ... passed all types of preliminary tests with positive results," a number of unpleasant surprises have revealed in the work of the 12-domed parachute system. . Already at the initial stage, it turned out that at large instrument rates of landing, the parachute system is distinguished by insufficient strength (terminals of the sling, tissue separations from the power framework of the main parachutes, "leading" by the filling process), and at the lower boundary of the specified high-speed application range - unsatisfactory Prices of domes of major parachutes. Analysis of the results of preliminary tests made it possible to identify the causes. In particular, an increase in the number of brake parachutes (their number corresponds to the amount of basic) led to the formation of a noticeable aerodynamic shading zone, which fell closer to the center of the dome of the main parachutes. In addition, the turbulence zone has formed behind the bunch of brake parachutes, which adversely influenced the filling process of the main parachutes in general. In addition, while maintaining the same length of the connecting links in the 12-dome system, as in the ISS-350-9, the "central" domes, the filling of which was delayed, turned out to be clamped by "leading" neighbors, and the "regulation" scheme of the disclosure process DVP worked not so effectively. This reduced the efficiency of the parachute system as a whole, increased the burden on separate dome. It was clear that a simple increase in the number of main domes would not be able to do.

NTK WVV, headed by Major General B.M. Ostrberhov, constantly paid the closest attention to developing both "object 950" and 4P248, as well as the refinement of landing and transport equipment of military transport aircraft - all these issues required a comprehensive solution. Especially since, in addition to the IL-76 (-76m) and An-22 aircraft, the combat vehicle was to land from just that had just entered the IL-76MD and who had passed the state test of heavy An-124 Ruslan. In 1986, in January and September 1987 and in 1988, on the initiative of the Airborne Forces, four operational assessments of 4P248 (PBS-950) were conducted, based on the results of which also made changes to the design of both the BMD itself and landing facilities.

The need to refine the rolling equipment of cargo cabs of military transport aircraft revealed already at the preliminary test phase. In the aircraft IL-76M (MD) to ensure the landing of three objects, the end portion of Montorels was extended, an additional fastening was introduced to the Monorail section. Two transshipment rollers were replaced: so that the machine, turning through the ramp, did not hold the side internal supply of the tail part of the cargo cabin, installed rollers with ring rollers holding the car from lateral displacement (such a solution was previously used when working out the system P-211 For the boat "Gagara"). Refinery and landing and transport equipment of the An-22 aircraft.

From January 5 to June 8, 1988, the system 4P248 with a parachute system of the ISS-350-12 (with an additional exhaust parachute of DVP-30) passed government tests. Directly supervised by the head of the Test Department of the State University of the Air Force, Colonel N.N. Nevzorov, the leading pilot was Colonel B.V. Oleinikov, leading navigator - A.G. Smirnov, leading engineer - Lieutenant Colonel Yu.A. Kuznetsov. Various options for landing on various venues were checked, including (at the final stage of the state test) to the aqueous surface. The act of state testing was approved on November 29, 1988

In the section "Conclusions" Act was said: "Bakhch-PDS targeting means of tactical-technical assignment No. 1998 and Supplement No. 1 mainly correspond, with the exception of the characteristics specified in PP .... Tables of conformity of this Act, and provide Parachute landing on the ground surface of the military machine of the BMD-3 flight mass of 14,400 kg with 7 members of the combat calculation, placed on universal seats inside the machine, from the heights of 300-1500 m on landing platform, having exceeded over sea level up to 2500 m, at wind speed Earth up to 10 m / s ... Means of landing "Bakhch-PDS" provide safety technical characteristics BMD-3, its weapons and equipment after parachute landing in the following versions of the machine picking:

Fully equipped with ammunition, operating materials, tablet property, full refueling of fuel, with seven members of combat calculation by a combat mass of 12900 kg;

In the above configuration, but instead of four members of the combat calculation, 400 kg of additional ammunition in the regular closure of a combat mass of 12900 kg;

With full refueling fuel, equipped with operational materials and a tablet property, but without combat calculation and ammunition with a total weight of 10900 kg ...

The landing of the BMD-3 on the means of landing "Bakhch-PDS" on the aqueous surface is not provided due to the tipping of the machine 180 ° at the time of the leading the wind in the surface layer to 6 m / s and the excitement of less than 1 point (i.e. in conditions , much more "soft" than those provided by TTZ. - Note. Avt.) ... Making a flight to landing the Battle Machine of the BMD-3 Tools on the means of "Bakhch-PDS" by the flight weight up to 14,400 kg, taking into account the features set forth in flight assessment , difficulties are not available and accessible to pilots, having experience in landing large cargo from IL-76 aircraft (m, MD) and An-22 .... The probability of trouble-free operation, determined with the trust probability of 0.95, is in the range from 0.952 to 1 , TTZ is given 0.9999 (excluding discharged to the water surface).

According to the results of state testing, the Means of landing 4P248 were recommended for the adoption of the supply of Air Force and Airborne Forces and to launch mass productionBut after the elimination of deficiencies and test tests.

The problems of the parachute system were manifested again: the destruction of one or two domes of the main parachutes, the terminals of the sling on the limit high-speed modes, in two cases - the unjuggestion of two domes when the BMD is dropped at 300-360 km / h from the heights of 400-500 m.

"Object 950", overturned with lateral demolition after landing. 1989

Analysis of comments and opportunities for their elimination forced to release the addition to TTZ. In order to prevent a long delay in the launch of targeting facilities into mass production, the requirement of landing to the aqueous surface is simply eliminated, and the flight rate for the instrument of landing was set to 380 km / h - to ensure safe exit of the product from the cab and disclosure of the parachute system. True, the same document implied additional flight and experimental studies to ensure the landing of the BMD-3 on the aqueous surface. The requirement was not formal - the studies held at the same time, in the late 1980s, studies, showed that even in the case of a non-nuclear scale war at the European Theater of Military Acts, up to half will be flooded due to the destruction of hydraulic structures Sushi surfaces. And it had to take into account when planning possible airborne operations.

The main improvements of the system have completed within a month. To accelerate the scattering of the BMD-3 from the means of landing into the design of the central node, a retreasing slider was introduced and one pouring point. In addition, they introduced screw supports and strengthened the fastening of the pipes of the central node. An additional compensators between the lever and the lock case appeared in the castle of fastening the object to Montorrels, the control stud to ensure reliable lock control in the closed position; The lock of the castle was finalized to speed up its installation in the monorail socket. Improved blocking unit in order to reduce its mass. Changed the design of the caterpilla covers, in order to reduce the likelihood of the caterpillars of the "object 950" caterpillars for elements of landing means at a congress with the "swollen" shock absorbers after landing. On the car healed the brackets for fastening skis. The design of the removable fencing of the BMD tower, which ensures the safety of the elements of the tower when the parachute system has joined the work: on state tests, for example, the bracket of the OU-5 illuminator on the tower was destroyed and the fence itself was deformed.

In the comments, it was indicated that the means of landing mounted on the machine in the march position allow the BMD to make a march "on rough terrain at a speed of 30-40 km / h to a distance of up to 500 km", but the requirements of TTZ were not fulfilled, since the placement of targeting facilities by car "The visibility of the commander has impairs from his workplace in position at a hiking day and with IR devices." The same applied to a review from the workplace of the driver's mechanics. With a given possibility of making long-term marches and overcoming water obstacles, the requirement was important. It was necessary to finalize the elements of fastening the means of landing on the machine at a hiking machine. Specified the requirements for the design and installation of universal seats of BMD.

Stages of booting bmd-z with means of towing PBS-950 per aircraft IL-76

Specialists of the NII AU redo the parachute system of the ISS-350-12. In particular, for hardening the domes of the main parachute on it in the pole part, 11 tapes of an additional circular framework from the technical capron tape LTKP-25-450 and LTKP-25-300 were found. To improve the filling and uniform loading of the parachute system, 20-meter extension cords were introduced, which allowed the domes of the main parachutes to diverge down from each other before disclosure. Changed the order of laying the brake parachute into the chamber. All the problems mentioned did not solve this, and at the launch of PBS-950 funds to production, it was necessary to limit the multiplicity of use on the limit high-speed modes, and to enter the PC-350-12 system to introduce an additional block of the main parachute and limit the multiplicity of application at the limit highly - speed mode.

From December 29, 1988 to March 27, 1989, preliminary flight tests of the revised funds of 4P248-0000 were held on an IL-76M aircraft belonging to AU. The influence of changes made to the design was checked at all stages of preparation for landing and towing himself. In particular, it was determined that the calculation of 7 people loads the "object 950" with the modified means of landing to the IL-76M aircraft for 25 minutes (the truth is not taken into account, the installation time of the UPS-14 of each object). The time for disconnecting the means of landing from the product after a landing was 60 s using the accelerated strolling system and no more than 2 minutes with a manual forces by 3 people calculated.

In the landing and transport equipment of the aircraft also made changes - in particular, in order to increase the safety of landing accompanying settlements with individual parachutes (this requirement was also included in the list of measures based on the results of state tests). Modified equipment with reinforced monorail 1P158, manufactured by the Universal Plant, was installed on the IL-76 plane OKB IS.S.V. Ilyushin and fully justified. In the report on these trials, approved by the supervisor and research institutes on March 30, 1989, said: "Remarks on the observations of G.

Means of landing 4P248 correspond to TTZ No. 1898 and Can be presented for control tests. With the exception: the loading time of the product "950" to the IL-76M aircraft on the TTZ-15 min was actually obtained 25 minutes, and the riming of means of landing after a landing is performed with an exit of 3 people from the product. "

Coarse testing of the air shock absorber on the layout of the "object 950"

Not without absent-free situations. In one of the flight experiments, the BMD "Object 950" after the landing is simply overturned up the caterpillars. The reason was the collision of the machine with a lateral demolition with a frozen snow shaft 0.3-0.4 m height (still winter) - and this case found "unsteady landing".

For the entire period of testing 4p248 during the tests (not counting the control), there were 15 coarse recesses of BMD layouts on the development of air shock absorbers; 11 Koprov drops "object 950" (of which four physiological experiments), 87 flight experiments with "object 950" layouts, 32 flight experiments with "object 950", of which four are physiological, with two tests inside the machine. For example, on June 6, 1986, parachutists testing NII AU A.V. Tests were landed on the land of landing under Pskov inside the machine from the IL-76 aircraft Shpilevsky and E.G. Ivanov (the height of landing - 1800 m, the flight speed of the aircraft is 327 km / h). On June 8 of the same year, parachutists of the Tests of the State Institution of the Air Force of the Air Force, Lieutenant Colonel A. A. Danilchenko and Major V.P. Nesterov.

In the report on the first summer physiological test, approved on July 22, 1988, was noted: "... At all stages of the physiological experiment, the tests retained normal performance ... Physiological and psychological changes in crew members were reversible and were reflected in the reaction of the body for the upcoming Extreme impact. " It was confirmed that the location of the members of the calculation on universal seats during the landing prevents strikes any part of the body about the body or the internal equipment of the combat vehicle. At the same time, the parachute system still did not provide the required fivefold application. Nevertheless, the decision of the Commander-in-Chief of the Air Force of November 16, 1989. PBS-950 landing facilities were adopted for the supply of Air Force, Airborne Forces and implemented in mass production, provided that the AU (in 1990 was renamed the Research Institute of Parachutivation) of the warranty multiplication of the Parachute System -350-12.

To confirm the effectiveness of the refinement of landing facilities in 1989 and 1990. Conducted additional control and special flight tests. As a result, the appearance was finally formed the appearance of the means of landing 4P248 (PBS-950), the design documentation was assigned to Litera Oh, i.e. For it, the installation lot of products for the organization of mass production could have been manufactured. During 1985-1990. On the development of 4P248 system, five copyright certificates were obtained regarding, mainly depreciation.

Decree of the Central Committee of the CPSU and Council of Ministers of the USSR No. 155-27 of February 10, 1990 for Arms Soviet army And the military fleet adopted a combat machine of the BMD-3 landing and the means of registering PBS-950. In the ruling, by the way, it was said: "To oblige the Ministry of Aviation Industry of the USSR to improve the landing and transport equipment and the staffing of the IL-76 aircraft, IL-76MD, AN-22 and An-124 devices for booting BMD-3 with the means of landing PBS-950 "

Floating tests

Order of the Minister of Defense of the USSR No. 117 dated March 20, 1990, I said: "To intend the Mattooing machine of the BMD-3 landing machine and the means of registering PBS-950 for staffing the parachuting parts of the Soviet Army and the parts of the Navy of the Navy, along with the battle machines, airborne bumps BMD-2, PRSM-915 parachute systems, PrSM-925 (916) and parachute free PBS-915 systems, PBS-916. The general customer for tutoring by the same order was determined by the Deputy Commander-in-Chief of Armed Air Force. Minaviaprom was obliged to create power calculated on the annual production of 700 PBS-950 kits. Take this (maximum) productivity, of course, have not yet intended. Real orders were planned much less. But they actually did not take place.

The first serial batch of PBS-950 in the amount of ten sets was manufactured in the same 1990 directly at the Universal Plant and transferred to the customer. This batch corresponded to the previously ordered VGTZ party from ten BMD-3. In total, the Universal CPC made 25 PBS-950 serial sets. At the time of the adoption of the means of landing PBS-950, their production was organized in Kumertau. But soon the events in the country made their own adjustments, and the mass production of PBS-950 was transferred to the Taganrog apo.

Despite the extremely unfavorable situation in the armed forces, work on the development of the few BMD-3 and PBS-950 in the troops still conducted, albeit with a significant delay. The ability to reset the BMD-3 using PBS-950 with all seven members of the calculation inside the car was tested in 1995 with a cooled drop. The first targeting of the calculation in full compound inside the BMD-3 with PBS-950 took place on August 20, 1998 during the displacement tactical teachings of the 104th GW. Parachute-landing shelf 76th GW. Airborne division. The landing was carried out from the IL-76 aircraft with the participation of military paratroopers: Senior Lieutenant V. V. KONEV, Junior Sergeants A.S. Aborn and Z.A. Bilimikova, Efreitor V.V. Sidorenko, ordinary D.A. Gorheva, D.A. Kondratieva, Z.B. Tonaev.

In the late 80s, the power and power of the Airborne Connections and the GRU special forces had to turn to the suppression of interethnic conflicts, which, like mushrooms after the rain, began to grow throughout the USSR, and later the CIS.

In the summer of 1987, the situation in Transcaucasia began to deteriorate in connection with the requirement of the Armenian part of the population of the Nagorno-Karabakh Autonomous Region (NKAO) on the withdrawal of Nagorno-Karabakh from the Azerbaijan SSR and the inclusion of it in the Armenian SSR. On February 28, 1988, the situation in the cities of Sumgait and Kirovabad came out of control. In Sumgait, the Azerbaijanis gathered to the rally moved to pogroms against the Armenian population, which were accompanied by looting, arson and murder. As a result of these inconsistencies, 26 Armenians killed in Sumgait for two days, more than 400 were injured, 12 Armenians were raped, set fire to more than 200 and plundered hundreds of apartments, destroyed more than 400 cars.

Reduce overload on chairs to TTT requirements (no more than 25 d) managed only to install the punches in the seating nodes.

BMD-1 leading on ZP170 landing agents.

Liberation of BMD-1 from targeting after a leading.

Landing the BMD-1 on the means of landing ZP170 in the mountains.

At this time, the military tests of the new Parachute system of the ISS-350-9 based on a unified block with a parachute with an area of \u200b\u200b350 m² were held. And the TSP170 facilities were also proposed in the embodiment with the ISS-5-128R system and with the new ISS-350-9 -9 -9 -9-in-in system with an exhaust parachute UPS-8 system.

If the multiplicity of the central beam is 20 or more times, the parachute system is up to 5 times at the ISS-5-128-R and up to 8 times at the ISS-350-9, then only once can be used to ski (folding) panels. However, it was not a significant disadvantage, since the combat use of targeting means is generally disposable.

The development of the SP170 lasted five years - from 1976 to 1981 the topic was protected by five copyright certificates. To understand how the scale of the work was carried out then when creating new landing systems, it was enough to mention that during the development of the SP170, 50 copp tests were carried out (of which 15 physiological, with tests, and three experiments on the aqueous surface), 103 flight experiments with discharging from three types of aircraft and in various climatic conditions (one physiological, with two crew members, and three on the aqueous surface).

The act of specifics of March 2, 1982, the product ZP170 was recommended for running into mass production and adoption for the supply of Air Force and Airborne Forces. On June 30, 1982, the Universal Plant presented to the Customer the serial documentation of the Frameless Tools for Tentizing the BMD-1 Machine with the crew.

Tactical and technical characteristics of free parachute facilities in comparison with the regimening system on a parachute platform

Meanwhile, there was already a test of another variant of the free parachute facilities of the BMD-1 landing agent, created under the direction of P.M. Nikolaev in the Feodosi branch automatic devices and received the "Shelf" cipher. It used newly developed NII AU Parachute systems of the ISS-350-9 and ISS-760F and the depreciation system for the development of the Feodosian branch. The Parachute system of the ISS-350-9 "lowered" the minimum height of landing to 300 m, which contributed to the accuracy of landing. Means of landing ZP170 and "Shelf" were offered in options using this system, although the state testing of the ISS-350-9 passed only in 1985. Shelf was also calculated to land the crew inside the car on Kazbek-D chairs. The composition of the shelf tanning tools included a parachute area with a parachute system, a cable system, a december locks, an ATS-2 signaling device, a guide orientation system, an amortization system mounted under the bottom of BMD, special equipment. A number of technical solutions and ready-made knots of the shelf system were borrowed from previously developed products of the Universal Plant.

In January 1979 V.F. Marghelova as the commander of the Airborne Forces was replaced by Colonel-General D.S. Sukhorukov. The new commander decided to carry out comparative tests of SP170 and Shelf systems. SP 170 showed not only reliable operation, but also a smaller time required for mounting and loading into a plane. After landing, the BMD-1 with SP170 was quickly represented. The system of "shelf" is simply "not lucky": the cables of the decontamination fell into the caterpillars of the machine, which significantly delayed the bringing to combat readiness. Nevertheless, the Commission was clearly inclined in favor of the shelf system. Apparently, the subjective opinion and sympathies of the new leadership played his role. But you need to recognize that the means of landing "Shelf" with self-filled aircraft gave overload when landing in the range of 15 d, i.e., ensured the safety of landing with a significant reserve with respect to TTT, specified by the Air Force in 1976. Yes, and the work of the Hydropic system in the shelf "It turned out to be more efficient. Shelf also passed tests to water towing.

One way or another, but the means of landing "Shelf" entered the supply of Air Force and airborne under the designation of PBS-915.

Serial production of PBS-915 "Shelf" ("Shelf-1") was transferred to the Kumertau Aviation production Association, and in the 1990s. - in Taganrog (OJSC Taganrog Aviation). Finally, in 2008, the production of PBS-915 was transferred to Moscow to the Federal State Unitary Enterprise "Universal" CPC.

As for the SP170 system, its main structural elements, as already mentioned, were used by the "wagon" specialists when creating targeting facilities for the BMD-3 combat vehicle on the topic "Bakhch-SD" (in the series, the designation of PBS-950). This, in particular, reference skiing with depreciation (only with the replacement of foam depreciation of air, forced filling) and the design of the central node. Also, when developing tighting facilities for BMD-3 and SPTP "SPTRUT-SD", a circuit of the ZKP lock with a duplicate system for switching on and switching the PRP to the crossing of an UPO link from the cargo to a parachute system similar to that was used in the SP170.
