A water-entry buffer device for a damping vehicle

Abstract

The present invention provides a damping type sailing body water entry buffer device, comprising a fairing, the head of which is sealed, and the tail is detachably connected to the outer wall of the head of the main body; the buffer device is arranged in the fairing and is located at the Between the head of the fairing and the head of the main projectile, it is used to buffer the force between the main projectile and the fairing after the main projectile enters the water; the electromagnet device is installed on The inside of the head of the main elastic body is used for absorbing the buffer device. The present invention is used for head load reduction in the process of airdropping or launching into water at medium and high speeds, and can be applied to the purpose of buffering and reducing load when the vehicle enters water at a vertical or large angle from 20m / s to 100m / s. The device has a relatively simple structure and is easy to implement and install. According to actual working conditions and needs, different hydraulic dampers can be adjusted or replaced to achieve different degrees of load reduction.

Description

technical field [0001] The invention relates to the technical field of water entry research of a vehicle, in particular to a damping water entry buffer device for a vehicle. Background technique [0002] The problem of water entry of the vehicle is of great significance in practical engineering. Modern underwater vehicles require a more flexible launch method to effectively avoid the tracking of radar and other devices. Therefore, more and more aerial vehicles are launched by means of airdrop or projection from airborne platforms. When an underwater vehicle or an air-launched torpedo falls from a high altitude, it will receive a huge impact load from the water surface at the moment it hits the water, which may cause damage to the complicated electronic equipment and other devices on the head of the vehicle or torpedo, thereby making it lose its function . When the water entry speed further increases, the impact load on the head also increases rapidly, so the probability of...
