Problems solved by technology

Explosive bolts, separation nut devices and other pyrotechnic devices have the advantages of light weight and convenient installation, but they often have a high impact response. When they are directly used in impact-sensitive parts such as payload separation, the high separation impact will cause severe damage to sensitive components. to adversely affect
It is difficult to meet the requirement of low impact by simply reducing the separation shock at the source of the pyrotechnic device, and there is a risk of reducing the separation reliability

Abstract

The invention discloses an impact-reducing separation structure suitable for an ignition actuating device. The impact-reducing separation structure comprises a first adapter block, a second adapter block, a base plate, a taper sleeve, a conductive screw and the ignition actuating device, wherein the base plate is connected with the outer end face of the first adapter block through the conductive screw; the inner end face of the first adapter block is attached to the inner end face of the second adapter block; one end of the taper sleeve is arranged in an internal through hole formed in the first adapter block, and the other end of the taper sleeve is arranged in an internal through hole formed in the second adapter block; and the ignition actuating device is arranged in an internal through hole formed in the base plate, an internal through hole formed in the first adapter block, a taper sleeve and an internal through hole formed in the second adapter block in a penetrating manner. The separation structure has the advantages of being low in impact response, high in bearing capacity, conductive and convenient to install, and a good impact environment can be provided for spacecraft instruments and equipment.

Description

technical field [0001] The invention belongs to the technical field of spacecraft structures, and in particular relates to a shock-reducing separation structure suitable for pyrotechnic devices. Background technique [0002] The main function of the separation device in the aerospace vehicle is to reliably connect the two bodies that need to be separated before the separation action, and to quickly cut off the connection between the two separation bodies when receiving the separation sequence. Explosive bolts, separation nut devices and other pyrotechnic devices have the advantages of light weight and convenient installation, but they often have a high impact response. When they are directly used in impact-sensitive parts such as payload separation, the high separation impact will cause severe damage to sensitive components. to adversely affect. It is difficult to meet the requirement of low impact by simply reducing the separation shock at the source of the pyrotechnic dev...
