Abstract

The invention discloses a satellite borne flat plate antenna articulated truss. The satellite borne flat plate antenna articulated truss comprises at least one group of rod components; each group of rod components includes a first supporting rod, a second supporting rod, a third supporting rod, a linkage supporting rod and an auxiliary supporting rod; one end of the first supporting rod is connected with a satellite platform through a satellite body supporting seat hinge; the other end of the first supporting rod is connected with one end of the second supporting rod through a multi-joint hinge; the other end of the second supporting rod is connected with an antenna inner plate through a first inter-rod hinge; one end of the third supporting rod is connected with an antenna outer plate through a frame supporting seat hinge; the other end of the third supporting rod is connected with one end of the linkage supporting rod through a second inter-rod hinge; the other end of the linkage supporting rod is connected with a multi-joint hinge; one end of the auxiliary supporting rod is connected with the third supporting rod through a third inter-rod hinge; and the other end of the auxiliary supporting rod is connected with the first inter-rod hinge. According to the satellite borne flat plate antenna articulated truss provided by the invention, a control system and a truss system are simplified, and inter-plate driving links can be reduced.

Description

technical field [0001] The invention relates to the technical field of aerospace vehicles, in particular to a articulated truss for a spaceborne 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 China started relatively late, and...
