Description

The invention relates to parachute techniques, in particular to parachute equipment when landing with a paratrooper heavy bulky cargo.

Currently, cargo containers (hereinafter referred to as the Civil Code) are used for landing with a paratrooper.

The used options for placing a cargo container have significant disadvantages that affect the safety of paratrooper landing.

A parachute system is known in which the HA is mounted on the chest of a paratrooper. Until the landing, the paratrooper is in a sitting position, and the main aircraft rests on the floor of the cargo compartment of the aircraft. In this case, the safety of the landing decreases, since the bulky GC makes it difficult for the paratrooper to move around the cargo compartment, maintaining the required time interval during group landing and when adopting the manufacturing position for safe separation from the aircraft. (N.A. Lobanov “Fundamentals of calculation and design of parachutes”, 1965, p. 344, Fig. 15.6.).

Closest to the invention in technical essence is a parachute system containing a parachute, a suspension system and a cargo container located on the back of a paratrooper (N. A. Lobanov "Fundamentals of calculation and design of parachutes", 1965, p. 330, Fig. 15.4. ) HA is mounted on the back of the parachutist under a satchel or below the satchel of the main parachute. In this case, it is difficult or impossible to place paratroopers in the airborne seats and their actions in the cargo compartment of the aircraft in flight according to landing commands. As the list and complexity of tasks expand, the nomenclature, mass and dimensions of the cargoes landed with a paratrooper increase.

The technical result of the invention is to increase safety and ease of use, as well as expanding the capabilities of landing with a paratrooper bulky heavy loads. A design of a human parachute system is proposed, which includes a suspension system to which a main parachute attached to the case and a cargo container located on the back of the paratrooper are attached. A distinctive feature of the proposed parachute system is that the main parachute, laid in a cover, is placed outside the paratrooper, in the cargo compartment of the aircraft and mounted on one of its elements.

In this case, due to the absence of the main parachute on the back, the placement of the paratrooper on the landing seat is not difficult, the weight of the aircraft in flight does not affect the paratrooper, but the shelf of the seat. The movement of the paratrooper inside the aircraft in flight, its actions on the landing commands, the adoption of the manufacturing position for separation from the aircraft (helicopter) does not cause difficulties.

After separation of the paratrooper from the aircraft, the main parachute is forcibly activated.

Depending on the weight of the main aircraft, it can land together with the paratrooper or separately from it (connecting link or your parachute).

The proposed parachute system (PS) is designed to increase safety, ease of operation and expand the capabilities of landing with a paratrooper bulky heavy loads.

Figure 1 shows the placement of a paratrooper with a parachute system on the landing seat of the aircraft.

Figure 2 shows the placement of the paratrooper in the cargo compartment of the aircraft in flight by the command "Prepare for the jump."

Figure 3 shows the descent of a parachutist on a parachute with a cargo container located on the back.

Figure 4 shows the detachment of the cargo container before landing and its descent separately from the paratrooper on the connecting link.

The parachute system consists (Fig. 1) of the main parachute 8, placed in the cover 1, and with the help of the free ends 7 connected to the suspension system 2, to which are also attached a spare parachute 3, placed, for example, on the chest of the paratrooper, and the cargo container 4 placed on the back of a paratrooper. In this case, the cargo container 4 is mounted on the back of the paratrooper so that when placing the paratrooper on the seat 6, the base of the cargo container 4 would rest on the above-mentioned seat 6. After the paratrooper is put into the aircraft, the main parachute 8, which is laid in the cover 1, is placed outside the paratrooper and fixed inside the cargo compartment of the aircraft, for example, to the cable 5 for the forced opening of the parachute 8. After the command "Get ready to jump" (figure 2) the parachutist, on the back of which the cargo container 4 is fixed, go through a hatch of an aircraft (not shown). In this case, the main parachute 8, laid in a cover 1, and suspended on a cable 5 moves behind the paratrooper. After separating the paratrooper from the aircraft, the main parachute 8 (Fig. 3) is forced into action.

Depending on the mass, the cargo container 4 can land together with the paratrooper (Fig. 3) or separately from it, for example, on the connecting link 9 (Fig. 4) or on its parachute (not shown in the drawing).

The proposed parachute system makes it possible to increase the safety and convenience of its operation, as well as to expand the possibilities of landing a paratrooper with a bulky heavy load.

Claims (1)

The human parachute system, which includes a suspension system to which the main parachute is attached, located in the case, and a cargo container located on the back of the parachutist, characterized in that the case with the main parachute is placed inside the cargo compartment of the aircraft and mounted on one of its elements .
