Abstract

The invention provides a satellite-borne deployable flat antenna support truss and an assembly method thereof. The satellite-borne deployable flat antenna support truss comprises a first antenna side plate, a second antenna side plate, an antenna middle plate, a first deployable mechanism, a second deployable mechanism, a first truss rod system and a second truss rod system, wherein the first antenna side plate and the second antenna side plate are symmetrically distributed with respect to a satellite platform, and are of the same structure; the antenna middle plate is fixedly installed on the top part of the satellite platform; the first deployable mechanism connects one end of the first antenna side plate and the satellite platform; the second deployable mechanism connects one end of the second antenna side plate and the satellite platform; the first truss rod system connects the other end of the first antenna side plate and the satellite platform; and the second truss rod system connects the other end of the second antenna side plate and the satellite platform. The satellite-borne deployable flat antenna support truss provided by the invention is simple in structure and convenient in assembly.

Description

technical field [0001] The invention relates to the technical field of aerospace vehicles, in particular to a support truss and an assembly method for a space-borne expandable flat-panel antenna. Background technique [0002] At present, there are many researches and applications on the expandable mechanism of satellite solar wings at home and abroad. The solar wings are deployed by passive mechanisms, and there is no special precision requirement after deployment in orbit; and the SAR flat panel antenna has a high impact on the accuracy of the shape and surface of the antenna after deployment. The electrical performance of the antenna has a direct impact on its imaging quality. In order to ensure that the SAR antenna maintains a relatively high rigidity after it is 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 Chi...
