Abstract

The invention discloses a satellite-bone planar antenna support girder. By optimizing a girder rod system, girder construction is achieved, the number of rod pieces and hinges are reduced, a light weight product is easy to achieve, and meanwhile, the working reliability of a product is improved. Multi-joint hinges, an antenna internal plate, an antenna external plate and a satellite plane in the support girder are connected in triangular construction, a plane formed by the multi-joint hinges and a satellite platform installation support is arranged in a plane formed by the multi-joint hinges and an antenna external plate installation support, and thus, the space torsion, the bending and support rigid of lateral swinging of the support girder are effectively improved.

Description

technical field [0001] The invention relates to the technical field of aerospace vehicles, in particular to a spaceborne planar antenna support truss. Background technique [0002] At present, there are many researches and applications on the expandable mechanism of the satellite solar wing at home and abroad, and there is no special precision requirement after the solar wing is deployed in orbit; and the SAR flat panel antenna has a direct impact on the electrical performance of the antenna due to the shape and surface accuracy of the antenna after deployment. It has a great relationship with its imaging quality. In order to ensure that the SAR antenna maintains a relatively high rigidity after being deployed in orbit, a rod system support scheme is usually used on the back of the antenna. The Canadian RADARSAT satellite is a typical application in foreign countries. The development of radar satellites in China started relatively late, and the antennas of remote sensing rad...
