Problems solved by technology

The working principle of the pyrotechnic method determines that the impact force is high during the unlocking and releasing process, which will have a certain impact on the attitude of the aircraft. At the same time, there will be certain pollution and debris, and the product structure design is relatively complicated.

Abstract

The invention discloses a non-pyrotechnic unlocking and releasing mechanism. The non-pyrotechnic unlocking and releasing mechanism comprises a baseplate, an outer container, a pull string a, a cover sealing piece, an inner container, a pull string b, a container sealing rope and an unlocking pull rope. The baseplate is mounted at the bottom of the outer container. The outer container and the baseplate are mounted and fixed at one end separated from a cabin section through nuts. A hanging seat is arranged on the baseplate. One end of the pull string a is connected with a hanging ring, and the other end of the pull string a is connected with the cover sealing piece. The hanging ring is connected with the hanging seat. One end of the unlocking pull rope is connected with the cabin section, and the other end of the unlocking pull rope is connected with the pull string b. The other end of the pull string b is connected with a hanging strip which is positioned in and connected with the inner container. The container sealing rope is connected to the joint of the unlocking pull rope and the pull string b. The non-pyrotechnic unlocking and releasing mechanism is low in impact force during unlocking and releasing, small in influences on attitudes of spacecraft, capable of effectively preventing debris pollution during unlocking and releasing, simple in structural design and high in high-temperature resistance.

Description

technical field [0001] The invention relates to a non-pyrotechnic unlocking and releasing mechanism, which is used for unlocking and releasing the payload after the cabin sections of the aircraft or spacecraft are separated. Background technique [0002] At present, the separation of aircraft or spacecraft compartments, and the unlocking and release of payloads mostly adopt the pyrotechnic method. The working principle is to ignite the main charge with an electric detonator, generate high-temperature and high-pressure gas, and break the weakening groove or cut off the shear pin. , release the payload lock state, and the payload is released. The working principle of the pyrotechnic method determines that the impact force during the unlocking and release process is high, which will have a certain impact on the attitude of the aircraft. At the same time, there will be certain pollution and debris, and the product structure design is relatively complicated. [0003] In order to...
