Description
Technical field
The present invention relates to a kind of can active synchronization begin to rehearse soon gas combined type air-drop buffer air bag.
Background technology
If directly contacted to earth when landing after being equipped in parachuting, moment impact overload will damage the frame for movement of equipment and the instrument of inside
Device equipment.It is thus desirable to absorb a part of impact energy by energy absorbing device.Widely used energy absorbing device mainly has
Compressible material, braking rocket and air-drop buffer air bag.Air-drop buffer air bag is compared other energy absorbing device and is had structure
Simply, easy to use, good buffer effect and low cost and other advantages.Air bag buffer system mainly by the buffering of air bag,
Absorb major part impact energy during land, alleviate and be equipped in the impact landed suffered by moment.Multinomial due to air-drop buffer air bag
Advantage, air bag buffer system is increasingly becoming one of important component part of equipment aerial delivery system.
Existing air-drop buffer air bag is mainly gravity type buffer air bag, and gravity type buffer air bag is by two parts of main and auxiliary air bag
Constituting, auxiliary air bag is in the outside of main gasbag, and communicates with main gasbag via passage.Air admission hole is positioned at bottom main gasbag, dress
During standby whereabouts, gravity type buffer air bag can be with self-inflating.After gravity type buffer air bag contacts with ground, air admission hole is closed.
The steam vent of gravity type buffer air bag is positioned in the middle part of auxiliary air bag side, is fitted by velcro at ordinary times, when in gravity type buffer air bag
When outer gas differential pressure is more than the adhesive force of steam vent, gravity type buffer air bag passes through steam vent exhaust pressure relief.This kind of airbag structure letter
Single, easy to use, but buffering effect is limited relatively big by environmental factor, particularly in high altitude localities, because atmospheric conditions affect,
Buffering effect is very poor.Especially relatively big at equipment volume, need to use under the situation of multiple air bag, due to each air bag simultaneously
There is the time difference in opening of exhaust outlet, the upset of equipment can be caused even to topple, and causes the serious damage of equipment.
The buffer air bag separately having a kind of novel equipment aerial delivery system is inflatable cushioning air bag.It is different from gravity type buffer air bag,
Without air admission hole bottom this kind of air bag, need to be by using gas cylinder that the air admission hole on air bag is inflated before throwing in or when throwing in, exhaust
Form is then identical with gravity type buffer air bag.This kind of air bag avoids the impact of atmospheric conditions, in high altitude localities using effect relatively
Good.But relatively big at equipment volume, need to use under the situation of multiple air bag simultaneously, equally can be due to the exhaust outlet of each air bag
Open and there is the time difference, cause the upset of equipment even to be toppled, cause the serious damage of equipment.
