Pneumatic artificial muscle contraction device for soft landing of airborne equipment

Abstract

The invention relates to a pneumatic artificial muscle contraction device for soft landing of airborne equipment, which belongs to the technical field of spaceflight. The pneumatic artificial muscle contraction device comprises pneumatic artificial muscle, a height sensor, a controller and a gas generator, wherein the pneumatic artificial muscle is connected with the gas generator through gas circuits; and the gas generator and the height sensor are respectively connected with the controller through circuits. The pneumatic artificial muscle contraction device adopts the pneumatic artificial muscle as a pneumatic executive element, and as the weight of the device is light, and the flexibility and the self damping property of the device are good, the device can effectively reduce the shock to the airborne equipment when the airborne equipment is landed by absorbing energy within a short time, therefore, the airborne equipment cannot be shocked and is not easy to be affected by external climate conditions.

Description

technical field [0001] The invention relates to a pneumatic artificial muscle contraction device for soft landing of airborne equipment, belonging to the field of aerospace technology. Background technique [0002] In the field of aerospace technology, the airborne landing of large-scale equipment such as airborne equipment and aerospace vehicles will involve the problem of soft landing, that is, landing at a relatively low speed is generally decelerated by the air resistance of the parachute, but the deceleration of the parachute has a certain To the limit, when the load is too heavy, the traditional parachute can no longer meet our requirements for landing speed by using air resistance buffering. Therefore, it is necessary to take further buffer landing and deceleration measures to slow down the airborne equipment or absorb the airborne equipment when landing. The falling kinetic energy can reduce the impact of landing and the peak acceleration; the cushioning airbag cushi...

[0002] In the field of aerospace technology, the airborne landing of large-scale equipment such as airborne equipment and aerospace vehicles will involve the problem of soft landing, that is, landing at a relatively low speed is generally decelerated by the air resistance of the parachute, but the deceleration of the parachute has a certain To the limit, when the load is too heavy, the traditional parachute can no longer meet our requirements for landing speed by using air resistance buffering. Therefore, it is necessary to take further buffer landing and deceleration measures to slow down the airborne equipment or absorb the airborne equipment when landing. The falling kinetic energy can reduce the impact of landing and the peak acceleration; the cushioning airbag cushioning device consumes energy within a limited distance after landing to achieve a soft landing, and the cushioning effect is obvious, but it is greatly affected by external weather conditions, resulting in poor stability; landing cushioning The rocket can achieve a soft landing with a large buffer stroke, and the landing speed can be buffered to zero, but the structure is complicated; the soft landing on the sea can significantly reduce the peak impact acceleration of landing, but it needs to control the landing position of the airborne equipment on the sea, which has great limitations
