Shock attenuation device suitable for high-altitude dropped object

Abstract

The invention relates to a shock attenuation device for a high-altitude dropped object, which comprises a buffering outer bag, a Ti -Ni alloy wire net, a buffering inner bag, hydraulic pipelines, an adjusting nut, a throttling nozzle, a supporting pallet and a sealing sheet, wherein the Ti -Ni alloy wire net is arranged between the buffering outer bag and the buffering inner bag, and the Ti-Ni alloy wire net and the supporting pallet are molded into a whole with a mould by technological vulcanization; the inner surface of the supporting pallet is provided with more than two hydraulic pipelines; one end of each hydraulic pipeline is communicated with the adjusting nut, while the other end is communicated with the liquid of the buffering inner bag; the adjusting nut is matched with the throttling nozzle through threads; and the outside of the adjusting nut is bonded with the sealing sheet. The shock attenuation device does not influence flight trajectory of the high-altitude dropped object, and always remains unchanged to the resistance of the dropped object in the whole buffering process so as to ensure uniform deceleration of the dropped object; and most external impact energy is dissipated in a buffering device, and almost no resilience force acts on the dropped object after the buffering process is finished.

Description

technical field

[0001] The invention relates to a shock-absorbing device, in particular to a shock-absorbing device suitable for dropping objects at high altitudes, and belongs to the field of material structures. Background technique

[0002] How to prevent the impact of the drop on the ground or water without affecting the trajectory of a system during airdrop deployment, and at the same time reduce the negative impact of the impact on the airdrop is the most important thing in the process of a system drop (deployment) An important part, the conventional practice is to install a parachute at the tail of the airdropped object. By increasing the damping area of ​​the airdropped object in the air, the descent speed is reduced to achieve the purpose of reducing the impact. Obviously, the method of installing the parachute is greatly affected by the climate environment, temperature, and wind direction, which will change the scheduled route of the airdropped object, have a great...
