Abstract

The invention provides a high-storage ratio on-orbit semiautonomous stretching-contracting spatial rollable metal surface antenna and a method. The high-storage ratio on-orbit semiautonomous stretching-contracting spatial rollable metal surface antenna is mainly composed of a hinge-type stretching arm, a rollable metal surface antenna, a storage tube, a stretching control assembly and the like, wherein the hinge-type stretching arm is fixedly connected with the rollable metal surface; the whole metal surface is driven to stretch outwardly through rotation of the storage tube and stretching and locking of the hinge-type stretching arm and reaches the working state; and the deformation energy of the metal surface can also provide partial power for the stretching process. Contracting and stretching of a satellite large-area antenna array surface can be realized; the metal antenna array surface is curled and contracted in a transmission process and is attached to the storage tube; after the satellite enters the orbit, according to a driving control instruction, an antenna surface required by a working state is formed through semiautonomous stretching; and the technique of the invention has the advantages of high storage ratio, light weight, high stiffness, high reliability, wide adaptability and the like.

Description

technical field [0001] The invention relates to the technical field of spacecraft structures, in particular to a space rollable metal surface antenna and a method thereof that are semi-autonomously deployed on orbit with a high storage ratio. 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...
