Abstract
The invention provides an inflatable radial rib antenna tail rod connecting piece for a spacecraft, and relates to an antenna tail rod connecting piece. The inflatable radial rib antenna tail rod connecting piece for the spacecraft is used for solving the problems that a radial rib antenna is high in carry cost, and a tail connecting piece is prone to deformation when the radial rib antenna is folded. The inflatable radial rib antenna tail rod connecting piece for the spacecraft comprises a carbon fiber rod, a tail rod inner sleeve, two locating press plates, two metal connecting pieces, four locking plates and two pieces of aramid fiber cloth. The tail rod inner sleeve is fixed at the upper end of an inner circumference surface of the carbon fiber rod. Two ends of one piece of aramid fiber cloth are aligned with two ends of the other piece of aramid fiber cloth, and are fixedly adhered together with the two ends of the other piece of aramid fiber cloth in an opposite mode. Holes are reserved in the middle of the two pieces of aramid fiber cloth. The top end of the carbon fiber rod is fixed in the holes. Two locking plates are arranged on the outer surface of each piece of aramid fiber cloth. Each two locking plates which are arranged in an opposite mode are fixedly connected with the two pieces of aramid fiber cloth. The two locating press plates are symmetrically arranged by using the axis of the carbon fiber rod as a center. Ends of the two pieces of aramid fiber cloth are respectively fixed with a metal connecting piece. The inflatable radial rib antenna tail rod connecting piece for the spacecraft is applied to the field of spaceflight.
