Air-drop protective system

Abstract

The invention relates to an air-drop protective system. The system comprises a parachute and at least one safety protective device, wherein the safety protective device comprises a safety air bag, an air generator and an impact switch; one end of the safety air bag is directly or indirectly connected with a carrier of the parachute, the other end of the safety air bag is connected with an air output end of the air generator, and the other end of the air generator is directly or indirectly connected with the impact switch. The system not only can enable air-drop objects to fall to the ground more stably and more safely during normal air drop, but also can have a certain protective effect on the air-drop objects, particularly on a pilot when the parachute cannot be opened normally within a set height; wind power has a smaller influence on the system during air drop.

Description

technical field [0001] The invention relates to an airdrop protection system capable of better protecting airdrops, especially pilots, during airdrop. Background technique [0002] With the development of society and the advancement of science and technology, the fields of application of airdrops are becoming wider and wider, and the requirements for airdrop technology are getting higher and higher. Airdrops have been widely used in disaster relief, transportation, escape, and troop delivery. [0003] Existing airdrop technology mainly adopts parachute, utilizes the resistance of air to the parachute, and the airdrop is thrown onto the ground at a uniform speed less than 8 meters per second. However, airdrops at a speed of 4 to 8 meters per second may also have a certain impact on the airdrops, especially causing damage to fighter pilots. Because fighter pilots use ejection to eject from the cabin when they start parachuting, and the acceleration of ejection is relatively h...

AI Technical Summary

Problems solved by technology

However, airdrops at a speed of 4 to 8 meters per second may also have a certain impact on the airdrops, especially causing damage to fighter pilots

Because fighter pilots use ejection to eject from the cabin when they start parachuting, and the acceleration of ejection is relatively high, which may cause brain blood loss to some pilots, leading to coma and temporary loss of consciousness.

When the pilot falls to the ground at a speed of about 5 meters per second, the unconscious pilot will still be injured because he cannot control his feet to support the ground

Another disadvantage of the parachute is that when the height of the parachute is lower than the design requirement, the parachute cannot be fully opened, and the speed of descent is very fast, causing the airdrop to collide with the ground and cause serious damage, especially causing severe injuries to the pilot, or even death

Some people have studied the installation of airbags at the bottom of the tank, and opened the airbags during the airdrop, which aggravates the impact of the wind on the airdrop. This method is not suitable for lighter airdrops

In order to enable fighter pilots to escape by parachuting at ultra-low altitudes, people have studied the "00" ejection seat, but when the flight state of the aircraft does not meet the design requirements, the "00" ejection seat cannot be ejected to the height where the parachute is fully opened and instead Casualties to pilots
