Abstract

The invention discloses a fusing type compression release mechanism and a release method thereof, wherein the release mechanism comprises a bearing rope, a heater, a fixed section, a separate spring and a separate section; the fixed section, the separate spring and the separate section are sequentially connected to the bearing rope; the separate spring is in compression state; the heater is placed on the bearing rope; two ends of the bearing rope defines the prolapse of the fixed section and the separate section; the release method comprises following steps: S91: connecting a main body structure to the fixed section and connecting a separate body to the separate section; S92: powering the heater and fusing the bearing rope; and S93: ejecting the separate body to the outside with the separate section under the effect of the separate spring. The fusing type compression release mechanism and the release method thereof has the advantages of light weight, simple structure, low cost and high reliability of releasing.

Description

technical field [0001] The invention relates to a compression release device, in particular to a fusing type compression release mechanism and a release method thereof. Background technique [0002] With the rapid development of aerospace technology, the development of small-sized, high-performance, and lightweight micro-satellites has become one of the key development areas of international aerospace groups. The various structural products on micro-satellites, such as communication antennas, small expandable solar cell arrays, etc., need to be compressed in the retracted state so that the structure of the launching section will not be damaged. The structure can be expanded. [0003] The current separation of spacecraft, such as the separation of satellites and rockets, the separation of stars, the release of battery wings or antennas, all use explosive bolts and other separation devices that use explosives as cutting power. This separation device has the characteristics of...
