A t-configuration solar cell array applied to microsatellites

Abstract

The invention provides a T-configuration solar cell array applied to a microsatellite, comprising: a connecting frame, a left panel of the solar cell array, a middle panel of the solar cell array, a right panel of the solar cell array, an inter-board hinge, a root hinge, and a left panel Time sequence unfolding mechanism and right panel time sequence unfolding mechanism; the left panel of the solar cell array is connected to the left side of the middle panel of the solar cell array via the inter-panel hinge, and the right panel of the solar cell array is connected to the solar cell array via the inter-panel hinge On the right side of the solar cell array mid-board, the connecting frame is connected to the upper side of the solar cell array mid-board through the root hinge; when it is in a folded state, the left board timing unfolding mechanism is installed on the left side of the T-shaped solar cell array , the right plate timing unfolding mechanism is installed on the right side of the T-shaped solar cell array. The T-configuration solar cell array is adopted, which has a small folding envelope, a large unfolding area, and a simple unfolding process.

Description

technical field [0001] The invention relates to a spacecraft structure, in particular to a T-configuration solar cell array applied to a microsatellite. Background technique [0002] With the development of aerospace technology, microsatellite platforms weighing 50Kg to 100Kg will carry single payloads with increasingly complex functions, resulting in a gradual increase in the energy demand of satellite platforms. At the same time, due to the miniaturization of the payload, microsatellites are also commonly equipped with remote sensing payloads with rotating parts. [0003] Traditional considerate solar cells and monolithic unfolded solar cell arrays are difficult to meet the increasing energy demand. The fundamental frequency of the one-dimensionally deployed solar cell array is low, and it is prone to frequency coupling problems with the satellite platform. The unlocking and unfolding mechanism of traditional solar arrays for large satellites is complex and expensive, an...

AI Technical Summary

Problems solved by technology

There are problems such as low deployment frequency, large length and field of view interference when deploying solar cell arrays in one-dimensional direction.

The solar cell array designed for the T-shaped configuration needs to control the deployment timing of the solar cell array. Large-scale solar cell arrays can be unlocked and deployed step by step through the compression and release device, but there are problems such as heavy weight, complex system, and high price.
