The invention relates to the technical field of carrier rockets, and discloses an auxiliary device for folding and unfolding a rudder and a folding and unfolding method of a carrier rocket rudder, the auxiliary device comprises a binding belt and a blocking and buffering piece, the two ends of the binding belt are detachably connected, and the binding belt with the two ends connected can be arranged outside the rudder and a rocket body in a sleeving mode so that the rudder can be located at the folding position; the two ends of the buffering piece can be rotationally connected with the launching pad and the rudder respectively, and when the two ends of the binding belt are not connected, the rudder can compress the buffering piece under the action of gravity and unfold from the folding position to the unfolding position. The folding and unfolding method comprises the following steps that the rudder is rotated to be attached to a rocket body; the binding belt is wound around the rudder and the rocket body, and then the two ends of the binding belt are connected, so that the rudder is fixed to the folding position; the stopping and buffering piece is connected between the launching pad and the rudder, the binding belt is detached, and the rudder rotates to the unfolding position from the folding position under the action of gravity; and removing the blocking and buffering piece. The folding and unfolding speed is high, and the cost is low.

    本发明涉及运载火箭技术领域,公开一种用于舵折叠展开的辅助装置及运载火箭舵的收展方法,辅助装置包括束缚带和阻缓件,束缚带的两端可拆卸连接,两端呈连接状的束缚带能套设在舵和火箭箭体外,以使舵位于折叠位置;阻缓件的两端能分别与发射台和舵转动连接,束缚带的两端未连接时,舵能在重力作用下压缩阻缓件,并由折叠位置展开至展开位置。收展方法包括以下步骤:将舵转动至贴合火箭箭体;将束缚带绕过舵和火箭箭体,然后将束缚带的两端连接,使得舵固定在折叠位置;将阻缓件连接在发射台和舵之间,拆掉束缚带,舵在重力作用下由折叠位置转动至展开位置;拆掉阻缓件。收展速度较快、成本较低。
