The invention relates to a high-speed underwater asymmetric buffer head cap of an aircraft. The high-speed underwater asymmetric buffer head cap comprises an outer housing, a buffer piece and a connecting piece. The housing is a sharp arch body connected with a cylindrical section, a buffer piece is arranged between the sharp arch body and the aircraft, a combining piece is arranged between the cylindrical section and the aircraft, and an asymmetric head cap relative to the axis is formed at the top end of the sharp arch body. The housing enables the aircraft to have a good pneumatic head shape, and the stability of the overall structure of the buffer head cap is guaranteed in the air flying stage; the buffer head cap is not broken when entering water, so that the aircraft is subjected tosmaller resistance of fluid when moving in the water and a flow field; the aircraft can be disengaged after reaching a preset posture, so that follow-up movement of the aircraft is not affected. The buffer piece is a revolving body, and hard polyurethane foam plastic is selected as a material for manufacturing the foam plastic buffer. A connecting piece employs an explosion screw and the head capis tightly fixed on the aircraft, and after the aircraft completely enters water, the bolt explodes after the aircraft deviates to a preset posture, so that the head cap is separated from the aircraft.
本发明涉及一种航行器高速入水非对称缓冲头帽,由外罩壳、缓冲件和连接件组成。罩壳为尖拱体连接圆柱段,尖拱体与航行器之间设有缓冲件,圆柱段与航行器之间设有结合件,在尖拱体的顶端形成相对于轴心的非对称头帽。罩壳使得航行器具有良好气动头型,在空中飞行阶段保证缓冲头帽整体结构的稳定性,入水时不破碎,使航行器在入水及流场中运动时受到流体更小的阻力作用,待航行器达到预定姿态后可以脱离,从而不影响航行器后续运动。缓冲件为回转体,选用硬质聚氨酯泡沫塑料作为制作泡塑缓冲器的材料。连接件采用爆炸螺丝,将头帽紧密固定在航行器上,航行器完全入水后,待其偏离到预定姿态,螺栓爆炸,从而使头帽与航行器发生分离。
