The invention relates to an aerospace structure design technology, in particular to a folding antenna mechanism of a cylindrical launch aircraft. Comprising an unfolding mechanism and a locking mechanism, the unfolding mechanism is used for unfolding the antenna which is not restrained by the launching cylinder after being launched; and the locking mechanism is used for keeping the unfolded antenna in an unfolded state. According to the folding antenna mechanism of the barrel type launch aircraft, it can be guaranteed that the antenna is folded in the aircraft body when the aircraft is in a launch barrel, storage and transportation are not affected, the antenna is rapidly unfolded and locked after launch, back-and-forth swing under the action of aerodynamic force is prevented, and the folding antenna mechanism is used for data transmission.
本发明涉及航空航天结构设计技术,具体涉及一种筒式发射飞行器折叠天线机构。包括:展开机构和锁定机构;所以展开机构用于对发射后失去发射筒约束的天线进行展开;所述锁定机构用于使展开后的天线保持展开状态。本发明提供的筒式发射飞行器折叠天线机构可以保证飞行器在发射筒内时将天线折叠在机体内部,不影响储存和运输,发射后快速展开并锁定,防止在气动力作用下来回摆动,用于数据传输。
