Problems solved by technology

The principle of point separation is as follows image 3 As shown, the docking surfaces 303 and 304 of the satellite and the rocket are screwed together. After receiving the separation command, the separation nut built in the lower separation device 302 is opened under the action of pyrotechnics, and the bolts built in the upper separation device 301 are simultaneously opened. It is pulled out under the action of the spring, so that the satellite is separated from the rocket. During this process, the impact load formed by the explosion of the pyrotechnics and the release of the deformation energy of the connection interface 305 will be directly transmitted to the on-board equipment through the main structure of the satellite. At the same time, due to the The structure is rigid, and the impact load is difficult to attenuate, which is very likely to cause damage to the satellite's precision electronic equipment

Abstract

The invention discloses a point type separation satellite and rocket butt joint structure which comprises a butt joint device of a cavity structure and a transition block, the butt joint device is installed on the satellite and rocket butt joint face of a rocket support, the transition block is installed between a satellite main structure and the butt joint device, and the upper surface of the transition block makes contact with the lower surface of the satellite main structure. And the lower surface is contacted with the upper surface of the butting device.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a point-type separation satellite star-rocket docking structure. Background technique [0002] With the development of the aerospace industry, the number of satellite launches has increased significantly. Especially in recent years, in order to realize Internet and Internet of Things services with sufficient global coverage, many units and companies at home and abroad have proposed low-orbit communication constellation solutions. This type of low-orbit communication constellation usually consists of dozens to hundreds of Satellite composition for Internet and / or IoT capabilities. These satellites are equipped with sophisticated electronic equipment. Once the electronic equipment fails, it will directly affect the normal operation of the satellite. [0003] Currently, most satellites use figure 1 The shown four-point connection is docked and installed with the rocket, wherei...
