Abstract
The present disclosure discloses a large space self-deployable boom. The problems that an existing antenna boom is complicated in structure and inconvenient to unfold or fold are solved. The boom comprises a plurality of stretching units which are coaxial and fixedly connected end to end in sequence, wherein each stretching unit comprises two fixing rings which are coaxially arranged up and down and a plurality of stretching main bodies uniformly distributed between the two fixing rings, the stretching main body is of a spring sheet structure, and when being on the ground, the plurality of stretching main bodies are bent by applying external force so that the folding of the boom is achieved, and the folding state is maintained through rope binding; after entering the outer space, the rope is cut off to realize the self-deployment of the stretching main body, so that the self-deployment of the boom is realized.
