Abstract
The invention discloses a reinforcing framework of a flexible parabolic antenna and belongs to the technical field of satellite-borne antennae. The problems that a single-layer flexible reflecting face structure is poor in deformation resistance capacity, prone to deforming and the like are solved. The reinforcing framework of the flexible parabolic antenna comprises four transverse ribs and ten air inflation supporting pipes. The four transverse ribs are arranged in parallel to form a trapezoid, the two ends of each air inflation supporting pipe are sealed, the two ends of each transverse rib are connected with the corresponding air inflation supporting pipes through tee joints, a connecting pipe is arranged in each tee joint to enable two adjacent air inflation supporting pipes to be communicated, and two air inflation holes are communicated with the air inflation supporting pipes at the two ends of one transverse rib respectively through one connecting pipe. The reinforcing framework of the flexible parabolic antenna is used for supporting the satellite-borne flexible single-layer parabolic antenna.
