Camera Stabilization System(Fig. 1.20) is intended for laying the stabilizing dome with slings and the upper part of the stabilizer into it, as well as for the orderly commissioning of the stabilizing system.

The shape is cylindrical. Material - kapron advice. It consists of a base (4) and those on it: in the upper part - a carabiner (1) for attaching to a cable or extension in an airplane, a lashing tape (7) for tying in a rubber honeycomb, a fuse (6) , drawstring cord (3) for tightening the camera; at the bottom - metal rings (5) for locking with stabilizer rings.

Stabilizing system (stabilizing strapless parachute) It is designed to put into operation a safety parachute device, to ensure a stabilized descent of the parachutist and to open the main parachute.

Stabilizing system ( rice. 1.21 ) consists of a canopy with lines and a stabilizer with a parachute link.

In the pole part of the dome there is an exhaust device (2), which is designed to ensure the filling of the dome and consists of eight pockets. Reinforcing tapes are sewn on the outer side of the dome: radial (3) - from the tape LTKP-15-185 and circular (4) from the tape LTKP-13-70. The edge of the dome is reinforced by folding the fabric to the outer side and stitched onto it on both sides with an LTKP-15-185 tape. Along the lower edge of the dome, under the radial reinforcing tapes, the ends of 16 slings made of the ShKP-200 cord are threaded and attached in a zigzag stitch. The length of the outer lines (6) in the free state from the lower edge of the canopy to the stabilizer feather is 0.52 m, and the middle lines (5) are 0.5 m. The canopy has a factory stamp (18): parachute index and year of manufacture.

The stabilizer serves to prevent rotation of the stabilizing parachute and consists of two feathers (7), each of which is made of gray nylon fabric and has the shape of an isosceles triangle. The feathers are stitched in height to form four stabilizer feathers. On the sides of each feather, LTKrP-26-600 ribbons are sewn, forming loops in the upper part, to which lines are attached, and in the lower part passing into a parachute link. A ribbon with a ring (17) is sewn on each side of the feather. The rings serve for locking them with the rings sewn on the chamber of the stabilizing parachute.

The parachute link (8) serves to connect the stabilizing parachute to the satchel during the stabilization stage and to the main canopy at all other stages of work, as well as to remove the stabilizing parachute from the paratrooper and ensure its stable operation. At a distance of 0.45 m from the stabilizer feathers, a loop (9) from the LTKrP-26-600 tape is sewn onto the link, which is intended for attaching the cord for turning on the parachute device. The lower part of the link branches out, forming power tapes (10), at the ends of which buckles (11) of a two-cone lock are sewn. Jumpers made of LTK-44-1600 tape are sewn on both sides of the power tapes. A loop (13) of LTKMkrP-27-1200 tape is sewn between the jumpers, which is designed to attach the stabilizing system to the bridle of the main parachute canopy and to the bridle of its chamber. On the loop there is a check-in tape (12) made of LTKrP-26-600 red nylon tape in three additions and designed for check-in of a removable honeycomb located on the ring of the right valve of the knapsack. One of the lashing concentrators has a loop for attaching to the loop of the parachute link of the stabilizing parachute, the other has a mark limiting the lashing.

The triangle formed from the ribbons is closed on both sides with kerchiefs (14) made of nylon advisor. A guide ring (16) is sewn onto the power tapes between the scarves using tape (15) LTKrP-26-600, through which the parachute device activation cord is passed. On the power tapes near the buckles, arrows are applied with black harmless paint to control the correct installation and installation of power tapes on a two-cone lock.

Parachute stabilizing strapless(Fig. 1.22) consists of a dome, a stabilizer and a parachute link.

The dome (1) has a hemispherical shape with an area of 1.5 m 2 and is made of nylon fabric. Radial reinforcing tapes (3)LTKP-15-185 and circular tapes (2)LTKP-13-70 are stitched on the outer side of the dome. The edge of the dome is reinforced with LTKP-15-185 tape stitched onto it on both sides. The canopy is marked with a factory stamp: parachute index and year of manufacture. _____________________________

The stabilizer serves to prevent rotation of the stabilizing parachute and consists of four feathers (4), which are made of gray nylon fabric. On the surface of each stabilizer feather, on both sides, a reinforcing frame made of LTKP-13-70 tape is sewn. The upper side of each feather is attached to the dome with the help of the bifurcated ends of the reinforcing frame tapes. On the sides of each feather, LTKrP-26-600 ribbons are sewn, which form a parachute link in the lower part. A ribbon with a ring (15) is sewn on each side of the feather. The rings serve for locking them with the rings sewn on the chamber of the stabilizing parachute.

The parachute link (5) is used to connect the stabilizing parachute to the backpack during the stabilization stage and to the main canopy at all other stages of operation, as well as to remove the stabilizing parachute from the main parachute and ensure its stable operation. At a distance of 0.45 m from the stabilizer feathers, a loop (6) from the LTKrP-26-600 tape is sewn onto the link, which is intended for attaching the cord for turning on the parachute device. The lower part of the link branches out, forming power tapes (7), at the ends of which buckles (8) of a two-cone lock are sewn. Jumpers made of LTK-44-1600 tape are sewn on both sides of the power tapes. A loop (10) of LTKMkrP-27-1200 tape is sewn between the jumpers, which is intended for attaching a stabilizing parachute to the bridle of the main parachute canopy and to the bridle of its chamber. On the loop there is a lashing tape (9) made of LTKrP-26-600 nylon tape of red color in three additions and designed for buckling a removable honeycomb located on the ring of the right valve of the knapsack. On one end of the lashing there is a loop for attaching to the loop of the parachute link of the stabilizing parachute, on the other there is a mark limiting the lashing.

The triangle formed from the ribbons is closed on both sides with kerchiefs (11) made of nylon advisor. A guide ring (13) is sewn onto the power tapes between the scarves using tape (12) LTKrP-26-600, through which the parachute device activation cord is passed. On the power tapes near the buckles, arrows are applied with black harmless paint to control the correct installation and installation of power tapes on a two-cone lock.

Main parachute chamber(fig. 1.23) is used for laying the canopy with the lines of the main parachute into it and for its orderly opening. The camera is made of gray nylon fabric and has the shape of a cylinder (when folded).

The surface of the chamber is reinforced with two tapes (2)LTKrP-26-600, which form a bridle in the upper part. For the convenience of laying the dome in the chamber along the upper base of the chamber and the bridle ribbons, our scarf (5). A cord-tie (3) from the ShKP-150 cord, which is designed to tighten the upper base of the chamber, is inserted and attached to the under-bend of the upper base of the camera.

On the base of the camera is sewn:

Nine straight (10) combs with ribbons (11) at the bottom for laying main parachute lines:

Honeycomb spreader (8) with honeycomb rubber (9) from knapsack cord to hold the lines in the comb;

Valve (15) with two pairs of eyelets (14) for passing removable rubber honeycombs (16, 17) and with two pockets (21) for covering bundles of lines; for the convenience of laying the slings, the valve near the eyelets is marked - 1,2,3,4;

Pocket (22) at the top base of the chamber for threading the ends of the cord-tie.

To cover the bundles of slings laid in honeycombs, aprons (7) made of gray nylon fabric with tie ribbons (6) are sewn in the upper part of the chamber.

A ring (20) of an elastic band 29 mm wide is inserted into the hem of the lower part of the chamber, designed to ensure an orderly exit of the main parachute canopy from the chamber.

At the lower base of the chamber, two removable rubber honeycombs are installed and an apron (19) is sewn on, which in turn has two more removable rubber honeycombs.

main parachute(Fig. 1.24) is designed to ensure a safe speed of descent and landing of a parachutist.

Consists of the base of the dome and lines. The base of the dome consists of 24 wedges (1), which form a non-planar circle with an area of 100 m 2 . Each wedge of the dome, in turn, consists of seven wedges, six of which are made of nylon fabric, and one wedge (2) 50 mm wide is made of excelsior fabric, which is a mesh. The wedges are interconnected with a seam "in the lock". On the seams connecting the wedges of the dome, nylon ribbons LTKP-13-70 are stitched. The lower edge of the dome is reinforced on both sides with nylon tape LTKP-15-185. On the lower edge of the dome, all slings, except for slings No. 1A, 1B, 13A, 13B, have jumpers made of nylon tape LTKP-15-185, which are designed to prevent cases of overlapping of the dome with slings and reduce its filling time. On the basis of the canopy, between lines No. 1A and 1B, 13A and 13B there are slots (3) 1.7 m long, designed to turn the canopy during descent. The main parachute (Fig. 1.25) has 26 main lines (1) made of ShKP-150 nylon cord (including 22 lines 4 m long and 4 lines (4) attached to the loops of the canopy slots, 7 m long), 22 external additional slings (2) 3 m long , as well as 24 internal additional slings (3) from a kapron cord ShKP-120 4 m long.

Additional lines are attached to the main lines, and two additional internal lines (3) are attached to lines No. 2 and 14 (5). The slings are tied at one end to the loops of the dome, at the other - to the half-ring buckles of the free ends (6) of the suspension system.

JSC Polet Ivanovo Parachute Plant is the only serial manufacturer in Russia of a wide range of parachute equipment for human use. The enterprise has state licenses for all types of activities related to the development, production and disposal of parachutes.

Paratrooper? What are they made from? You will find answers to these and other questions in the article. A parachute is a device made of fabric, made in the form of a semicircle, to which a load or suspension system is attached with straps. It slows down the movement of an object in the air. Parachutes are used to delay the movement of winged vehicles during landing and jumps from fixed objects (or from aircraft) for the purpose of reliable descent and landing of cargo (people).

Varieties

Many people are interested in knowing how many lines a paratrooper's parachute has. At first, air umbrellas were used for a soft landing of a person on Earth. Today, with the help of them, people are rescued, parachuted from the air. In addition, they serve as sports equipment.

Cargo sky umbrellas were invented for landing cargo and cars. Several such devices can be used simultaneously for landing heavy equipment. Rescue systems on light aircraft are a variation of them. Such devices consist of a parachute and forced extension accelerators (rocket, ballistic or pyrotechnic). When a dangerous situation arises, the pilot activates the rescue equipment and the plane parachutes to the ground. These practices are often criticized.

Small stabilizing parachutes (which are also exhaust parachutes) regulate the position of the body during a relaxed descent. Restraint air umbrellas were developed to shorten the stopping distance on vehicles and ships, to stop cars in drag racing. For example, Tu-104 aircraft and early Tu-134 models were equipped with such devices.

Parachutes are also used to reduce the speed of a spacecraft when landing on a celestial object or while moving through the atmosphere. It is known that ordinary round sky umbrellas have been developed for landing people and cargo. And there are also round parachutes made in the form of a Rogallo wing, with a retracted apex, band parachutes for supersonic speed, parafoils - wings in the form of an ellipse or a rectangle, and many others.

Devices for disembarking people

So, how many lines does a paratrooper's parachute have? For a safe landing of a person, experts have developed the following types of air umbrellas:

special purpose;
rescue;
training;
landing;
shell gliding parachute systems (sports).

The basic types are landing (round) parachutes and "wing" systems (shell gliders).

Types of army "air umbrellas"

Each soldier should know how many lines a paratrooper's parachute has. Army sky umbrellas come in two types: square and round. The canopy of a landing round parachute is a polygon, which, when filled with air, takes the form of a hemisphere. The top has a cutout (or less dense fabric) in the center. Such systems (for example, D-5, D-10, D-6) are distinguished by the following high-altitude characteristics:

working usual height - from 800 to 1200 m;
the maximum height of the ejection is 8 km;
the lowest ejection level is 200 m with a descent on a filled canopy of at least 10 seconds and a stabilization of 3 seconds.

Round landing parachutes are difficult to control. They have approximately equal horizontal and vertical speed (5 m/s). The weight of these devices is as follows:

13.8 kg (D-5);
11.7 kg (D-10);
11.5 kg (D-6).

Square parachutes (for example, the Russian "Leaf" D-12, T-11 USA) have additional slots in the arch, with the help of which the parachutist controls the horizontal movement. They also improve maneuverability. The horizontal speed of products is up to 5 m/s, and the speed of descent is up to 4 m/s.

D-6

And now let's find out how many lines the D-6 paratrooper's parachute, which was developed by the Research Institute of Parachute Engineering (Aviation Equipment Holding), has. It is used for combat and training jumps from transport aircraft. Previously, it was used by the USSR.

Today, the modified D-6 device of the fourth series, along with the new D-10, is used by flying clubs and airborne troops. Its domed corrective system consists of lines, a stabilizer with a link, and a top base. Along the lower edge of the vault, under the reinforcing radial tapes, 16 ropes from the ShKP-200 kapron rope are threaded and stitched. The length of the extreme lines, placed in a free state on each loop, from the lower edge of the top to the stabilizer loops, is 520 mm, and the middle ones are 500 mm.

Nuances D-6

The base of the D-6 dome is made of nylon material art. 560011П, and the overlay is made of the same fabric, but has art. 56006P. Between the lines No. 15A and 15B, 1A and 1B, on the basis of the dome there are slots of 1600 mm in size, designed to turn the arch during descent. At the top there are 30 cables made of ShKP-150 kapron rope. To the free edges of the suspended structure No. 2 and 4, 7 lines are attached, and to No. 1 and 3 - 8 lines each.

The length of the straps in a free position from the half-ring buckles to the lower edge of the dome is 9000 mm. Marks are drawn on them at a distance of 200 mm from the lower edge of the vault and 400 mm from the half-rings-buckles of the free ends. They are great for facilitating the installation of dome cables. Coordination ropes are sewn to slings No. 15A and 15B, 1A and 1B. The dome has an area of 83 sq. m.

Control lines are made of kapron red harness ShKPkr. They are passed through rings sewn to the inside of the free ends of the suspension structure.

D-10

And now we’ll tell you how many lines the D-10 paratrooper’s parachute has. It is known that this sky umbrella replaced the D-6 parachute. Its squash-shaped dome, with beautiful appearance and improved performance, has an area of 100 square meters. m.

The D-10 device was made for the landing of novice paratroopers. With it, you can perform combat and training jumps from the transport-military Il-76, An-2 aircraft, Mi-6 and Mi-8 helicopters. On the ejection, the flight speed is 140-400 km / h, the smallest jump height is 200 m with stabilization for 3 seconds, the maximum is 4000 m with a flight mass of a person of 140 kg, the decrease occurs at a speed of 5 m / s. The D-10 parachute has different line lengths. It weighs little and has a lot of control options.

Each soldier knows how many lines the main parachute of the D-10 paratrooper has. The device has 22 ropes with a length of 4 meters and 4 cables connected to the loops of the dome slots, 7 m in size from a nylon rope ShKP-150.

The parachute is also equipped with 22 additional external lines from the ShKP-150 harness, 3 m long. In addition, it has 24 internal additional ropes from the ShKP-120 harness, 4 m in size, attached to the base lines. Cables 2 and 14 are connected by a pair of internal additional slings.

D10P

What is a good landing parachute? D-10 and D10P are amazing systems. The D10P device is designed so that it can be converted to D-10 and vice versa. It can be practiced without stabilization for forced opening. And you can attach it, put the parachute to work with adjustment - and into the plane, into the sky ...

The D10P dome is made of 24 wedges, the lines have a tensile strength of 150 kg each. Their number is identical to the number of cables of the sky umbrella D-10.

Spares

And how many lines does a paratrooper's reserve parachute have? It is known that the design of the D-10 allows the use of spare air umbrellas of the 3-5, 3-4, 3-2 types. The opening of the two-cone lock is insured by parachute devices PPK-U-165A-D, AD-ZU-D-165.

Consider a reserve parachute 3-5. It consists of the following parts: a canopy with lines, a suspension intermediate system, a satchel, a manual opening link, a parachute bag and a passport, and auxiliary parts.

The reserve parachute contributes to the creation of a safe rate of descent (landing). This is a load-bearing surface made in the form of a framed surface layer with load-bearing parts that connect the top to the suspended intermediate system.

The parachute has a round arch with an area of 50 square meters. m, which consists of four sectors made of five nylon panels. These components are sewn together with a seam in the lock.

24 slings made of ShKP-150 nylon rope are attached to the dome hinges. Their longitude in a free position from the lower edge of the arch to the half-rings of the suspended intermediate system is 6.3 m. To simplify the laying of the arch, the 12th line is made of a red cord (or an identification red sleeve is sewn on it).

On each rope at a distance of 1.7 m from the lower edge of the vault there is a black mark indicating the place where the lines are laid in the cells of the pack.

Interaction of parts

If the main parachute does not work, the paratrooper must sharply pull out the pull ring of the manual opening element by hand. As a result, the pockets of the exhaust device, located around the pole clearance, being in the air stream, pull out the vault and lines of the reserve parachute from the satchel and remove the person from it.

Under the influence of air flow, the dome of this device fully opens, providing a normal landing.
