Abstract

The invention provides a satellite and rocket docking device, and relates to the technical field of spaceflight overall configuration. The satellite and rocket docking device comprises a main cylinder, a backland plate connecting frame and a satellite and rocket docking frame, wherein the a circular opening is formed in the bottom of the satellite and rocket docking frame; a square opening is formed in the top of the main cylinder. The satellite and rocket docking frame disclosed by the invention is suitable for a total carbon fiber composite circumference transition satellite and rocket connecting device of a grillage type configuration GEO satellite platform, uniform transition of a whole satellite mechanical load from a box-shaped grillage to a circular delivery butting ring is realized, and as a corn component of the device, the grillage type satellite configuration forms a favorable force transmitting path. The rigidity, the intensity and the stability of the whole satellite device all meet design requirements, and a solid basis is established for the configuration design of the whole satellite.

Description

technical field [0001] The invention relates to the technical field of overall spaceflight configuration, in particular to a satellite-rocket docking device. Background technique [0002] With the rapid development and maturity of electric propulsion technology, electric propulsion technology has been gradually applied on GEO satellites, from north-south position maintenance and partial orbit change, to the use of electric propulsion to realize all orbit change and on-orbit position maintenance tasks. The application of electric propulsion technology can greatly reduce the amount of propellant carried and reduce the weight of satellite launches, so as to realize the launch of two satellites with one arrow and effectively save launch costs. [0003] Due to the application of electric propulsion technology, especially the use of all-electric propulsion to complete the orbit change task, the propellant carrying capacity of GEO satellites has been significantly reduced, and the ...
