Abstract

A connection and separation device for spacecraft, which is composed of an initiating element, an inner actuator, an outer actuator, etc., and is screwed together with the first connection object through a lock nut arranged on the casing, and is screwed with the second connection object through a lock rod. connected together, so as to realize the reliable connection of the first and second connection objects. When separating, the high-pressure gas generated after the detonating element is detonated drives the movement of the inner and outer actuators respectively, and then completes the unlocking and separation, and realizes the ejection of the second connection object. The device of the present invention is simple in structure and easy to use. As long as one of the inner and outer actuators acts, the unlocking and separation can be completed. Even if one of the actuators fails, the separation will not fail, so it has the advantage of high reliability. .

Description

technical field

[0001] The invention relates to a connection and separation device for space vehicle compartments or parts. Background technique

[0002] During the launch and in-orbit flight of the spacecraft, reliable connections are required between the spacecraft and the launch vehicle, between the spacecraft body and components, and between the cabin sections. The assembly that requires separation is unlocked and separated according to a predetermined procedure to ensure that the flight The successful completion of the task. Usually, the connection and separation between the spacecraft and the launch vehicle, between the spacecraft body and its components, and between the cabin sections are realized by means of connection and separation devices.

[0003] The connection and separation device is generally composed of connection and unlocking parts, separation parts, etc., and has the functions of connection, unlocking and separation. The connection function refers to co...
