The invention provides a non-fixed-connection interstage separation structure and an aircraft, the rear section part of an interstage conical plate is fixedly connected to the separation section of the aircraft, and the front section part of the interstage conical plate is tightly pressed on the outer surface of the aircraft; the front section part of the interstage conical plate is not mechanically and fixedly connected with the aircraft; before interstage separation, the interstage conical plate front section part and the interstage conical plate rear section part are matched with the height difference between the two stages of the aircraft to form an aerodynamic configuration; during interstage separation, the separation section of the aircraft is separated from the rear section part of the interstage conical plate, meanwhile, the constraint on the front section part is released, and the front section part is separated from the aircraft under the action of aerodynamic force. The aerodynamic configuration of the aircraft can be in smooth transition in the interstage section, the aerodynamic configuration of the aircraft can be maintained before interstage separation, and the aircraft can be quickly and smoothly separated during interstage separation.
本发明提供了一种非固连级间分离结构及飞行器,级间锥形板后段部分固接于飞行器分离段,将级间锥形板前段部分压紧在飞行器外表面;级间锥形板前段部分与飞行器不存在机械固连;级间分离前,级间锥形板前段部分、级间锥形板后段部分匹配于飞行器两级间的高度差形成气动外形;级间分离时,飞行器的分离段连同级间锥形板后段部分一起脱离,同时释放了对前段部分的约束,前段部分在气动力的作用下与飞行器分离。使飞行器气动外形在级间段能够光滑过渡,在级间分离前能维持飞行器的气动外形,级间分离时能够快速与飞行器顺利分离。
