Problems solved by technology

Obviously, the method of installing a parachute is greatly affected by the climate environment, temperature, and wind direction, which will change the scheduled route of the airdropped object and have a greater impact on the trajectory of the airdropped object, making it impossible to accurately deliver the airdropped object to the predetermined location

Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and working principle.

[0013] Such as figure 1 As shown, the present invention is composed of a buffer outer bag 1, a Ti-Ni alloy wire mesh 2, a buffer inner bag 3, a hydraulic pipeline 4, an adjusting nut 5, a throttle nozzle 6, a supporting plate 7 and a sealing sheet 8 .

[0014] The outer surface adopts a streamlined design of buffer outer bag 1 and buffer inner bag 3, and the material is rubber products. There is a super-elastic Ti-Ni alloy wire mesh 2 in the middle of the inner and outer buffer bags. The weaving method of the alloy wire mesh is implemented The standard is: GF2W 2.00 / 0.5 (plain weave) GB5330-85. During processing, the buffer outer bag 1, Ti-Ni alloy wire mesh 2, buffer inner bag 3 and support plate 7 are vulcanized into one buffer bag through the process. The vulcanization process Similar to the processing process of a basketball, it is...

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 not affect the trajectory of a weapon system during airdrop deployment, and at the same time prevent the drop from colliding with the ground or water, and reduce the negative impact of the impact on the airdrop is a weapon system drop (deployment) process. The most important part of this method 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 greater impact on the trajecto...
