Abstract

The invention discloses a pneumatic connecting and unlocking device. The device comprises a cylinder body, a piston assembly, a locking nut, a screw, a cylinder cover and an elastic returning element, wherein the piston assembly comprises a piston, a sealing ring, an unlocking and separating pushing rod, a multifunctional electric element and a pressing plate. The pneumatic connecting and unlocking device is applicable to powerful connection and weak unlocking of two articles; after unlocking and separating, the cylinder cover can be dismounted and mounted again for recycling; the problem of connecting and unlocking the two articles with high connecting power and small unlocking power can be solved.

Description

technical field [0001] The invention belongs to the technical field of spacecraft connection and separation structures, and in particular relates to a pneumatic connection unlocking device. Background technique [0002] Connection, unlocking and separation are important actions during the flight of the spacecraft system, such as separation between stages, fairing throwing separation, tail cover separation, flap separation, head-to-body separation, etc., satellite solar wing deployment, antenna deployment, etc. [0003] At present, there are mainly two types of connection unlocking devices used on spacecraft: point connection and line connection. Typical point connection unlocking devices include explosive bolts, unlocking bolts, and separation nuts, etc. Typical linear connection unlocking devices include shaped explosive cables. , airbag explosive cables, expansion tubes, etc.; this connection and unlocking method is mostly driven by the pyrotechnic system, and there is pol...
