Aerospace craft segment separation device

Abstract

The invention discloses an aerospace craft segment separation device which comprises a sliding cylinder (1), a separation spring (2), a sleeve (3), a sleeve fixing nut (4), a plug cover (5), a sliding rod (6) and a plug screw (7). Movement of the separation spring (2) on the normal plane of the center axis is limited through the sleeve (3), in the axial direction, the separation spring (2) is limited through the plug cover (5), the sliding rod (6) and the sliding cylinder (1), the sliding rod (6) is installed on the plug cover (5), the sliding cylinder (1) is installed on a separation section, when the separation spring (2) is released, a movable part moves relative to a fixed part and is stuck at the tail portion through threads along with release of the separation spring (2), and the plug cover (5) is moored; meanwhile, axial movement of the separation spring (2) is limited through the plug cover (5) and the separation spring (2) is moored. By means of the device, the risk that a moving object collides with an engine effuser or an upper-level instrument device can be effectively avoided, and separation reliability is improved.

Description

technical field [0001] The invention relates to an aerospace vehicle segment separation device. Background technique [0002] When many aerospace vehicle sections are separated, a separation spring is used to provide the separation momentum. Generally, the separation spring is installed on the structure of the separation section, and the separation spring is in a compressed state before separation. During the separation process, the structural parts such as the separation spring and the blocking cover installed in the structure of the separation section will quickly follow the separation of the section. Released as a free movable object, due to the large number of separation springs and the possibility of external interference in the separation process, in the high-speed separation state, there is a risk that the released movable object will collide with the nozzle of the main engine and the upper-stage instruments and equipment. The flight will be affected, and serious fli...

Generally, the separation spring is installed on the structure of the separation section, and the separation spring is in a compressed state before separation. During the separation process, the structural parts such as the separation spring and the blocking cover installed in the structure of the separation section will quickly follow the separation of the section. Released as a free movable object, due to the large number of separation springs and the possibility of external interference in the separation process, in the high-speed separation state, there is a risk that the released movable object will collide with the nozzle of the main engine and the upper-stage instruments and equipment. The flight will be affected, and serious flight failure will be caused. Therefore, it is necessary to limit the free moving objects generated during the separation process to avoid damaging the nozzle or colliding with instruments and equipment.
