Abstract

The present invention provides a multi-functional bulkhead structure for a microsatellite system and relates to the field of designing of spacecraft structures and power supply systems. The multi-functional bulkhead structure comprises a carbon fiber support structure, lithium ion batteries, a balance charging circuit, an electrical connector, a voltage display module and the like, and functions of force bearing, power supplying, balance charging and the like are integrated. According to the multi-functional bulkhead structure, the integrated design of the power subsystem, the structure subsystem and the state detection subsystem is realized, and the issues of long life, heat dissipation and the like of the multi-functional bulkhead structure are fully taken into consideration. The multi-functional bulkhead structure for the microsatellite system has the advantages of small size, light weight, long life, good compatibility with the satellite overall and the like, and the application to a microgravity air flotation simulation satellite shows that the multi-functional bulkhead structure for the microsatellite system effectively reduces the weight of an air flotation simulation satellite body and increases the effective load carrying space of the air flotation simulation satellite.

Description

technical field [0001] The invention relates to the technical field of spacecraft structure and power supply system design, in particular to a multifunctional bulkhead structure for a microsatellite system. Background technique [0002] Microsatellites refer to satellites with a weight of less than 1000kg, which have the characteristics of low cost, short development cycle, and strong functionality after networking. Especially in recent years, with the rapid and practical use of microsatellites (weighting 10kg to 100kg), a large number of microsatellite systems with clear uses have emerged. Such as the "Tiantuo" series satellites of the National Defense University, the "Innovation No. 1" of the Chinese Academy of Sciences, and the "Aerospace Tsinghua No. 1" of Tsinghua University. In order to realize the miniaturization and miniaturization of the satellite, various instruments and equipment contained in it must be miniaturized and integrated as much as possible. For example...
