Problems solved by technology

[0003] The purpose of the present invention is to solve the problems of complex structure, easy failure, poor deployment reliability, heavy overall weight and low folding efficiency in use of the traditional unfolded solar cell array using a mechanical rigid structure, and the use of a large-area plane The structure stiffness and fundamental frequency decrease with the increase of the structure size in the frame-type deployment structure, which is easy to cause resonance with the main body of the satellite, and it is difficult to control the attitude of the solar cell array. A truss-type solar cell array that can be rigidized and inflated is provided.
2. Since the present invention adopts a truss-type solar cell array that can be rigidized and inflated to expand, it solves the problem that the traditional deployable solar cell array adopts a mechanical rigid structure, which has complex structures, easy failures, poor deployment reliability, and overall weight in use. The problem of heavy weight and low folding efficiency and the solar cell array adopting a large-area planar frame-type unfolded structure have structural stiffness and fundamental frequency that decrease with the increase of the structure size, which is easy to cause resonance with the main body of the satellite, and it is difficult to control the attitude of the solar cell array The problem

Abstract

Disclosed a girder-like solar energy battery array which can spread via aeration relates to a solar battery array used in the spacecraft. The invention can solve the problems of traditional folding solar battery array which uses the mechanical rigid structure, with complex structure, worse folding reliability and lower folding efficiency; and the problems of large-scale plat frame folding structure as the reduction of structural rigidity and basic frequency with the increase of size. Wherein, the girder (3) is formed by the connection between a group of girder units, while the same planes of each girder unit have basic plates to be fixed via the belt; the upper end surface of basic plate has a solar battery panel (2); the initial end of girder (3) is connected to the connection disc (8) of aeration end; one end of wire (6) is connected to the electric heating layer (3-6) of main supporting tube; one end of aeration tube (5) is inside the main supporting tube which has a control valve (7); and the tail end of girder (3) is connected to the connection disc (9).

Description

technical field [0001] The invention relates to an expandable solar battery array used on space vehicles such as satellites or manned spacecraft, in particular to a truss-type solar battery array that can be rigidized and inflated to expand. Background technique [0002] Solar cell array is the main form of power supply for space vehicles such as satellites, and has been widely used in space vehicles such as satellites, manned spacecraft, and space stations. The development of modern aircraft technology requires larger and larger solar cell arrays to provide higher energy power supply. The traditional deployable solar cell array mainly adopts a mechanical rigid structure. This deployable support structure is composed of many rigid components connected through a connecting mechanism, a control deploying mechanism and a locking mechanism. In use, there are complex structures, easy failures, and deployment Poor reliability, heavy overall weight, and low folding efficiency (suc...
