Abstract

The invention provides an on-orbit inflatable inflatable satellite that can be inflated and expanded, comprising: a satellite core, a support body and a satellite shell, the satellite core is arranged at the center of the satellite shell, and the satellite core and the satellite shell are connected with support body. The satellite core contains the electronic components of the satellite, and the support body is composed of an inflatable expanded support tube. The upper surface outside the satellite shell is used to paste flexible solar cells to form a body-mounted solar cell array, and the lower surface outside the satellite shell uses shaping technology to form the shape of the antenna, and install antenna component modules to form a body-mounted antenna . The present invention adopts a substantially spherical inflatable unfolding structure, and there are no flexible structures such as large-scale long-arm solar panels and space-borne antennas after forming, thus greatly improving the overall structural rigidity of the satellite and improving the overall vibration fundamental frequency of the satellite. Compared with existing satellites, the fundamental frequency of vibration is increased by 5 to 10 times. The overall dynamic characteristics of the satellite have been improved, and the overall stability of the satellite has been improved.

Description

technical field [0001] The invention relates to an inflatable inflatable satellite that can be inflated and deployed in orbit, and belongs to the technical field of satellites. Background technique [0002] With the improvement of the comprehensive level and technical capabilities of satellite platforms, the size of space-borne flexible accessories such as solar panels and antennas continues to increase, which leads to a decline in the overall dynamic performance of satellites. The reduction of these performances will lead to the reduction of the performance of the satellite in the following aspects: 1. Due to the low fundamental frequency of structural vibration, it is difficult to guarantee the shape and surface accuracy of the satellite-borne antenna, thus greatly reducing the accuracy and strength of the entire satellite’s sending and receiving signals. ; 2. Due to the greatly reduced overall structural stiffness and vibration fundamental frequency of the satellite, the ...
