Main framework of small high-orbit satellite public platform

Abstract

The invention provides a main framework of a small high-orbit satellite public platform, the main framework of the small high-orbit satellite public platform comprises a shell, a middle partition plate, a platform cabin main bearing truss group and a load cabin bearing truss, the shell forms an accommodating space, and the middle partition plate divides the accommodating space into a platform cabin and a load cabin; the platform cabin main bearing truss group is arranged between a part of the shell and the middle partition plate which form the platform cabin and applies supporting force to thepart of the shell and the middle partition plate which form the platform cabin; the load cabin bearing truss is arranged between part of the shell and the middle partition plate which form the load cabin, and applies supporting force to the part of the shell and the middle partition plate which form the load cabin; the load cabin bearing truss is cylindrical, satellites are connected to the upperportion of the load cabin bearing truss in series for inter-satellite series structure design and mechanical transmission while the load cabin bearing truss bears satellite loads, and the inter-satellite series structure is used for a launching task of one rocket and two satellites of a small high-orbit satellite.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a main structure of a common platform for small high-orbit satellites. Background technique [0002] The main structure of satellite platform is one of the core technologies of satellite products. The main structure with high bearing ratio, high specific stiffness, high specific strength, low cost and easy mass production and development is an effective guarantee for the competitiveness of satellite products. The truss-type satellite main load-bearing structure has the advantages of high net space value, simple and efficient force transmission characteristics, less restrictions on the carrying envelope, good stiffness and integrity, and is increasingly used as the main load-bearing structure in satellite public utilities. Among the platforms, such as the BSS-601 / BSS-702 / BSS-702SP series platforms of Boeing Company of the United States. And for the high-orbit satellite public ...

AI Technical Summary

Problems solved by technology

At this stage, there is no successful all-electric push satellite platform in my country, and its high load-carrying ratio, high specific stiffness, high specific strength, low cost and easy to mass-produce the truss-type main load-bearing structure are particularly urgent and important.
