Description

SUBSTANCE: invention relates to means of life support for skydivers at high altitudes during preparation for a jump, leaving an aircraft and parachuting.

It is known that in order to avoid oxygen starvation at altitudes above 3000 meters, it is necessary to use oxygen equipment that provides an increase in the percentage of oxygen in the inhaled air.

The standard oxygen equipment of a parachutist jumping from high altitudes consists of a cylinder with an oxygen supply, an oxygen device and a mask that provide oxygen from the device to the human respiratory organs.

A known set of oxygen equipment KKO PDR for paratroopers ("Airborne training", Sitnikov I.V., Gazin V.N. Voenizdat, 2005), which is used when making parachute jumps from a height of more than 4000 meters. KKO PDR includes oxygen devices KP-43, KP-58 and an oxygen mask KM-19 with an economizer in the form of a rubber bag. On board the aircraft, the kit is connected to the onboard oxygen system, and after separation from the aircraft, oxygen is supplied from the KP-43 parachute oxygen device.

The applicability of the KKO PDR when performing jumps from a greater height using modern parachute systems that provide a long-term controlled gliding descent of a parachutist is limited due to the fact that:

- the oxygen supply in the KP-43 device is designed for only 10-13 minutes of operation, which is not enough when performing high-altitude jumps using modern parachute systems that provide a controlled gliding descent of a parachutist;

- as oxygen is produced, its consumption decreases;

- placing a rubber bag on an oxygen mask creates operational inconvenience and the possibility of damage.

A set of oxygen equipment and equipment for high altitude jumps is known according to patent RU 2695573 dated 01/19/2017, adopted as a prototype, including a protective helmet, an oxygen mask with a hose, an onboard oxygen equipment unit, a parachutist's oxygen equipment unit, oxygen hoses and a junction box.

The disadvantage of the prototype is the limitation of its use in height - up to 10,000 m.

The objective of the invention is to create a set of oxygen equipment and equipment for jumping from a greater height, allowing it to be used at altitudes up to 15,000 m, providing a stable oxygen supply of a parachutist with oxygen during the entire landing cycle, including flight to the jump, preparation for the jump and parachuting.

The problem is solved due to the fact that the protective helmet is additionally equipped with a booster tank, the oxygen mask is additionally equipped with an exhalation-boost valve, the junction box is additionally equipped with an air suction valve to compensate for the deficiency of the air mixture, while the booster tank when connected to the exhalation-boost valve of the oxygen mask creates excess pressure in the submask space.

The inventive set of oxygen equipment and equipment for jumping from a great height is represented by figures 1-5.

Fig. 1 is a general view of a set of oxygen and high jump equipment.

Fig. 2 is a schematic diagram of a junction box.

Fig. 3 shows the construction of a protective helmet.

Fig. 4 shows the construction of an oxygen mask.

Fig. 5 shows the construction of an oxygen mask valve box.

The set (Fig. 1) contains a protective helmet 1, an oxygen mask 2 with a hose 3, a junction box 4, oxygen hoses 5, 8, an onboard oxygen equipment unit 6, a parachutist's oxygen equipment unit 7. The junction box 4 is connected to the oxygen mask by means of a hose 3 2, through the hose 5 - with the onboard oxygen equipment unit 6, through the hose 8 - with the parachutist's oxygen equipment unit 7.

Junction box 4 (Fig. 1, 2) is an economizer and is designed to provide oxygen supply to mask 2 from blocks 6 and 7, contains fitting 9 for connecting block 6, hose 8 for connecting block 7, fitting 10 for connecting oxygen mask 2, additionally contains an air suction valve 11.

In the absence or insufficient supply of oxygen during inhalation, breathing air enters through valve 11, made as part of a junction box.

Protective helmet 1 (Fig. 3) is designed to protect the parachutist's head from impacts and the impact of the air flow when leaving the aircraft, descending and landing. Behind the suspension system 12 of the protective helmet 1 there is a tank for creating excess pressure (retaining tank) 13 with a fitting 14.

Oxygen mask 2 (Fig. 4) with oxygen-respiratory equipment is designed to provide oxygen supply to the skydiver during desaturation, preparation for the jump and parachuting, contains an exhalation-recharge valve (Fig. 5) located in the valve box 15, and a fitting 16 for connection expiratory-support valve with a holding tank 13.

The retaining tank 13, when connected to the exhalation-pressure valve of the oxygen mask 2, creates excess pressure in the undermask space due to the expansion of the air contained in the tank depending on the height, which allows the use of the inventive set of oxygen equipment and equipment for jumping from a height of up to 15,000 m.

Before the flight, the parachutist must put on a protective helmet 1 and an oxygen mask 2 with a hose 3, install the junction box 4 and the parachutist's oxygen equipment unit 7 on the parachute system, connect the hose 8 from the junction box 4 to the block 7, connect the fitting 14 of the retaining tank 13 to the fitting 16 expiratory-pressure valve of the oxygen mask 2.

Before the jump, to prevent decompression disorders, oxygen is breathed from the onboard block of oxygen equipment 6 for a specified time, for which it is necessary to connect the hose 5 from the block 6 to the junction box 4, connect the oxygen mask to the protective helmet 1 and pull it to the face, open the oxygen supply from block 6 and block 7.

Due to the pressure difference in blocks 6 and 7, oxygen supply to mask 2 will be carried out only from block 6.

Immediately before the jump, you must switch to breathing from block 7, for which disconnect hose 8 of block 7 from the junction box 4. The oxygen supply from block 6 will stop, oxygen will begin to flow into mask 2 from block 7.

When canceling or delaying the jump, the hose 8 must be connected to the junction box 4, there will be an automatic transition to the skydiver's breathing from block 6.

During the parachutist's descent, breathing will be performed from block 7.

Thus, the introduction of additional elements: a retaining tank in the design of a protective helmet, an exhalation-pressure valve in the design of an oxygen mask, an air suction valve to compensate for an air mixture deficiency in the design of a junction box - when connecting a retaining tank with an exhalation-pressure valve of an oxygen mask, to create an excess pressure in the mask space, which makes it possible to use the claimed set of oxygen equipment and equipment for high-altitude jumps, oxygen supply of the parachutist with oxygen throughout the entire landing cycle, including flight to the jump, preparation for the jump and parachuting from a height of up to 15,000 m.
