RU211196U1 - PARACHUTE SYSTEM SACKET - Google Patents

Abstract

The utility model relates to parachute technology and is designed to improve the convenience and safety of parachute jumps by armed paratroopers from various aircraft and helicopters.

A distinctive feature of the claimed utility model is a fundamentally new layout of the parachute system satchel: the rejection of the design of the satchel with only one compartment for placing the main dome and lines in the chamber (or in the case) and the transition to a satchel with a compartment for weapons and ammunition, a compartment for a dome with lines and with a cargo compartment. Naturally, the satchel is located on the back of the parachutist, the compartment with the main dome is on top, and the weapons compartment is on the side along the satchel. With this arrangement, below the main dome compartment there is room for a cargo compartment with a capacity of up to 60 liters. The cargo compartment contains an inner container (bag) for direct placement of cargo, fastened with a 10-12 meter cord to the bottom of the parachute harness.

The inner container (bag) can be dropped by a parachutist at a certain distance from the ground by pulling out a special cable with a pin that closes the device that holds the cargo compartment in a closed state.

The free volumes of the compartments of the knapsack and the bottom of the knapsack are filled with a foamed substance (for example, polyethylene foam), which provides positive buoyancy of the parachute in the event of a parachutist entering the water, which increases the possibility of his rescue.

The transfer of the attachment point of the stabilizing parachute above and further from the limbs of the paratrooper reduces the possibility of the paratrooper catching the link of the stabilizing parachute after separation from the aircraft (helicopter) in comparison with the currently operated landing parachutes.

Thus, a positive effect is achieved - the placement of paratroopers in the cockpit is improved and the safety of parachute jumps is increased.

Description

The backpack of the landing parachute system (PS) is an element of parachute equipment and an integral part of the human parachute system. In the general case, it is designed for compact placement on a parachutist of a parachute canopy with lines in a chamber (case), a stabilizing device, a parachute automatic device and for putting them into action in a given sequence.

The backpack of a modern PS on the example of PS D-10 is a rectangular structure consisting of a hard bottom and two avisent valves for placing under them and holding a camera with a dome and slings on the bottom of the satchel. The shape of the bottom of the knapsack is determined by the steel wire frame. In the upper part of the frame there is a metal plate with windows for the stabilizing device, a two-cone lock to hold the stabilizing device until the paratrooper pulls out the exhaust ring (or the parachute device is triggered). On the right flap there is a pocket for an automatic parachute device of the PPK-U-165 type (or AD-3-ud). On the outer side of the knapsack there are elements of its fastening to the suspension system and other auxiliary elements.

Similarly, differing in the geometric dimensions of the bottom and valves, the knapsacks of all modern domestic PS used by paratroopers and paratroopers (D-1, D-3, D-5, D-6, PTL-72, DM-7, PD-47) .

The described configuration of PS backpacks has been replicated for about 90 years (since the beginning of the 30s of the 20th century) and is “classical” in design and universal in use for almost all types of PS - sports, training, landing, rescue, training, special - and for all types of skydiving, respectively.

At the same time, over such a long period of time, the composition of weapons, equipment, uniforms and means of communication of paratroopers has changed radically, i.e. armed paratroopers performing special tasks determined by state laws and military regulations. Universal landing craft with unified backpacks do not fully allow safe and convenient landing of personnel from existing transport aircraft and helicopters.

The currently used equipment, in terms of its dimensions (length), does not allow placing it on a paratrooper so that this equipment makes it possible to comfortably seat paratroopers on seats in airplanes or helicopters, which negatively affects the fatigue of paratroopers during long flights. The abnormal placement of paratroopers on the seats makes it difficult for the aircraft crew members and issuers (parachute service specialists) to move around the aircraft cabin.

The proposed airborne PS backpack is distinguished by its suitability for parachute jumps by paratroopers who have weapons, equipment and uniforms for performing special tasks. The backpack and its elements are shown in Fig. one.

The suitability of the proposed satchel PS includes the following items:

1. The presence of three compartments (compartments) on the knapsack:

- for the main parachute;

- for weapons;

- for cargo.

2. Restriction on the height of the backpack placement on the parachutist (not lower than the level of the buttocks);

3. The introduction of elements of constant positive buoyancy into the design of the parachute and knapsack (11);

4. Moving the attachment point on the backpack of the stabilizing parachute to a zone that excludes its engagement with the limbs (arms and legs) of the parachutist.

In FIG. 2 shows a satchel as part of a parachute system worn by a paratrooper. You can see the limitation of the backpack and equipment in height (along the lower edge of the backpack), which makes it possible to conveniently place paratroopers on the seats of aircraft and helicopters. The option of landing paratroopers on the seats is shown in Fig. Z.

Structurally, the proposed knapsack is a rectangular frame made of steel wire, covered on both sides with nylon avisent, which is the bottom of the knapsack.

A compartment (container) (2) for weapons in the form of a cylinder fastened with a zipper is sewn to the left edge of the knapsack.

The container (1) of the main dome is sewn to the upper edge of the satchel. The containers of the main dome and weapons in the upper are sewn together, which provides a three-dimensional design and its necessary rigidity during landing.

On the outer side of the main canopy container there is a locking device for holding the container lid and a two-cone lock (or a coneless lock) (4) for holding the power bands of the stabilizing parachute until the paratrooper pulls out the exhaust ring or until the parachute device is triggered.

In the upper part of the side walls of the parachute container, steel rings (5) are mounted for the power bands of the stabilizing parachute, through the rings and stabilization bands (6) the traction force of the stabilizing parachute is transmitted to the suspension system. The rings are connected to the suspension system by stabilization bands (6).

Below the parachute container is the cargo compartment (3). The outer shell of the cargo compartment has the shape of an inverted truncated pyramid, the lower (small) edge sewn to the lower edge of the bottom of the knapsack. The upper part of the shell of the cargo compartment has a locking device (7), with the help of which the filled shell is fixed by the upper part of the compartment to the bottom of the knapsack. The fastened part of the shell is held by a manual opening link and, depending on the size of the load, can be dropped (unfastened) by a paratrooper by pulling out the link, or (if the weight of the load is small), the paratrooper can land with the load.

Inside the shell of the cargo compartment, a package (bag, container) (8) is placed for direct placement of the cargo. The package (bag, container) has a system of straps on the outer surface for covering the stowed cargo and is connected by a 10-12 meter cord (9) to the lower part of the PS suspension system.

The position of the load (8) dropped during descent is shown in FIG. 5.

Possible placement of elements of positive buoyancy and displacement of the attachment points of the stabilizing parachute is shown in Fig. 3 and FIG. four.

Below the knapsack (if necessary), a serial dropable cargo container GK-30 (10), shown in Fig. 3.
