Abstract

The invention provides a cubic satellite unlocking and separating mechanism and a separating method thereof. The cubic satellite unlocking and separating mechanism mainly comprises a main frame structure, a satellite separating structure, an electromagnetic locking and unlocking structure and a holding brake self-locking structure, wherein a satellite ejection rail is arranged in a main frame; theelectromagnetic locking and unlocking structure is used for locking or unlocking a top cover and the main frame by utilizing two power-losing electromagnets; when the holding brake self-locking structure is locked, the satellite is locked in the unlocking and separating mechanism, the influence of the vibration on the satellite can be effectively reduced, and the satellite can be prevented from being popped out in advance during the popping process of the top cover; and the cubic satellite can be separated after the top cover is completely opened, self-locking can be realized after the top cover is opened to a set angle, and the top cover can be prevented from rebounding to interfere with cubic satellite separation. The unlocking and separating mechanism is light in weight, small in size,high in reliability, capable of ensuring safe launching of the cubic satellite and high in satellite launching success rate.

Description

technical field [0001] The invention relates to the technical field of satellite launch, in particular to a cubic satellite unlocking and separating mechanism and a separating method thereof. Background technique [0002] In recent years, more and more scientific research institutes and commercial companies have turned their attention to CubeSat based on the advantages of short development cycle, low manufacturing cost, and low R&D expenses of CubeSat. In the process of launching the cube star, the separation of the satellite and the rocket is an important part of the launch procedure. Therefore, for the unlocking separation mechanism, whether it is technical or structural research, it is of great significance to the satellite industry. Most of the traditional satellite separation mechanisms are connected by pyrotechnics. However, these methods have the disadvantages of high cost, large impact, heavy pollution, high power consumption, and low separation speed. And it may ...
