The invention relates to a high-speed water entry buffer head cap of an underwater vehicle. The high-speed water entry buffer head cap comprises an outer cover shell, a combined buffer piece and a combining piece. The outer cover shell is installed outside the whole buffering head cap, so that the aircraft has a good pneumatic head shape, the stability of the whole structure of the buffering headcap is guaranteed in the air flying stage; the buffering head cap can be integrally broken and disintegrated when entering water, and the movement performance of the aircraft in water is not affected.The combined buffer piece can isolate the impact when entering water to reduce and limit the water entering impact load acting on the aircraft. The combined buffer piece is a revolving body and bonded at the front end inside the cover shell, a groove is formed in the rear end of the buffer and completely wraps the head of the aircraft, and the combined surface of the combined buffer piece and thebuffer serves as a supporting surface and a supporting point for combining the aircraft and the head cap. A connecting piece adopts a spring clamp device to guarantee firm and reliable connection between the aircraft and the buffer head cap, and resistance to disengagement loads of the aircraft in various mechanical environments such as impact, vibration and external loads in the carrying and running process is realized.
本发明涉及一种水下航行器高速入水缓冲头帽,由外罩壳、组合缓冲件和结合件组成。外罩壳安装在整个缓冲头帽的外部,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,入水时能够整体破裂解体,不影响航行器在水中的运动性能。组合缓冲件在入水时能够隔离冲击,降低与限制作用在航行器上的入水冲击载荷。组合缓冲件为回转体,粘结在罩壳内部前端,缓冲器后端有一凹槽,完全包裹航行器头部,两者结合面成为航行器与头帽结合的支撑面和支撑点。连接件采用弹簧夹装置来实现保证航行器与缓冲头帽牢固可靠连接,能抵抗航行器在载送和运行过程中的各种冲击、振动和外载荷等力学环境下的脱体载荷。
