Vibration reduction air bag for hoisting and air drop of helicopters

Abstract

The invention relates to a vibration reduction air bag for hoisting and air drop of helicopters. The vibration reduction air bag comprises a lower supporting plate, a valve bottom plate, an air bag lower fixing plate, an upper supporting plate, an air bag upper fixing plate, valve hinges, valve on-off time adjusting springs, a center positioning telescopic sleeve, a valve on-off control tower spring and an air bag body. The air bag lower fixing plate is connected with the valve bottom plate which is connected with the lower supporting plate, the air bag upper fixing plate is connected with the upper supporting plate which is matched with the lower supporting plate, the valve on-off time adjusting springs are connected with the valve hinges which are connected with the valve bottom plate, the center positioning telescopic sleeve is penetratingly arranged on the valve bottom plate, the valve on-off control tower spring is connected with the valve hinges through valve connection structures, and the air bag body is arranged between the air bag lower fixing plate and the air bag upper fixing plate. The vibration reduction air bag has the advantages that by the aid of a buffering air release valve, pressure change rate of the air bag can be controlled automatically, twice buffering can be realized, and the air bag is excellent in vibration resistance; the vibration reduction air bag is low in production cost, simple in structure, high in reliability, free of maintenance and convenient to use; furthermore, the vibration reduction air bag is small in space occupancy after folded, thereby storage is facilitated.

Description

technical field [0001] The invention relates to the field of air transportation, in particular to a vibration-damping airbag for helicopter hoisting and airdropping. Background technique [0002] The use of airdrops and helicopters to quickly hoist and replenish ammunition in emergency situations without follow-up support in the context of large-scale combat operations is currently the best means of ammunition supply. However, helicopters fly, land, and When hovering, it is vulnerable to enemy ground weapons. In addition, the shock and vibration of landing on the ground like airdrop parachute also seriously affects the safety of ammunition. Contents of the invention [0003] In order to solve the problems of the prior art, the embodiment of the present invention provides a helicopter hoisting with excellent anti-seismic function, low production cost, simple structure, high reliability, free from maintenance, convenient to use, small space occupied after being folded, and c...
