Abstract

The invention discloses a space columnar paraboloid thin plate antenna based on an inflatable structure. The antenna comprises a thin plate antenna, the inflatable structure, a storage tube and a support arm. The thin plate antenna is fixedly connected with the inflatable structure and is folded on the storage tube. The support arm is arranged on the lower end of the inflatable structure. According to the invention, the antenna has the advantages of simple design construction and good processing manufacturability and assembling manufacturability; the thin plate antenna construction is used; deformation energy is stored in a folded state; deformation energy is released in an unfolding process; the power consumption demand of a drive device is reduced; the antenna has the characteristics of large storage capacity and light weight; the inflatable structure is used; the inflatable structure is inflated to unfold the entire antenna surface; the unfolding surface of the antenna is ensured; and the unfolding stiffness of the antenna surface is improved.

Description

technical field [0001] The invention relates to the technical field of spacecraft structures, in particular to a space columnar parabolic thin-plate antenna based on an air-filled structure. Background technique [0002] In order to solve the contradiction between the large-area antenna array of the spacecraft and the size limit of the carrying envelope, the spacecraft needs to gather the antenna on the star during the active launch phase, and unfold and lock the antenna to the working state after entering orbit. At the same time, on the basis of meeting the requirements for antenna use, satellites have increasingly stringent requirements for the lightweight antenna structure, and put forward higher requirements for the envelope, storage ratio and weight of the extension device. Therefore, conventional antenna deployment and retraction configuration design can no longer meet the above various requirements. Contents of the invention [0003] In order to solve the above tec...
