A composite load-reducing device for high-speed water entry of a vehicle

Abstract

The invention provides a composite load-reducing device used for high-speed water entry of a vehicle body, which includes a fairing detachably connected to the head of the main body, a cavitator in the fairing and a damping device, and the damping device is arranged on the fairing Inside, and between the cavitator and the main elastic body; the damping device includes a sealed pressure cylinder, a piston, a mounting seat, a piston rod, a tension spring, an air cavity and a buffer gas. The invention is a cushioning and shock absorbing device which utilizes a pneumatic damping device and cushioning foam to reduce load. At the same time, the pneumatic damping device and cushioning foam are used for cushioning, which has stronger load reduction performance.

Description

technical field [0001] The invention relates to the technical field of water entry of a vehicle, in particular to a load reduction device that adopts a combination of aerodynamic damping type load reduction and physical foam type load reduction for buffering, and in particular relates to a composite buffer load reduction device for a vehicle body entering water at high speed device. Background technique [0002] Modern underwater vehicles require more flexible launch methods to effectively avoid tracking by radar and other devices. More and more underwater vehicles are launched by air delivery. When an underwater vehicle or an air-launched torpedo falls from a high altitude, the head of the vehicle will be subjected to a huge short-term impact pressure at the moment it hits the water, which may cause damage to the internal structure of the vehicle, especially the electronic equipment. The probability of this kind of damage increases rapidly with the increase of the impact v...
