Damping type buffering device for underwater entry of navigation body

Abstract

The invention provides a damping type buffering device for underwater entry of a navigation body. The damping type buffering device comprises a fairing, a buffering device body and an electromagnet device, wherein the head of the fairing is sealed, and the tail of the fairing is detachably connected with the outer wall of the head of a main elastic body; the buffering device body is arranged in the fairing, located between the head of the fairing and the head of the main elastic body and used for buffering the acting force between the main elastic body and the fairing after the main elastic body enters water; and the electromagnet device is installed in the head of the main elastic body and used for attracting the buffering device body. The damping type buffering device is used for head load reduction in the air-drop or medium-high-speed launching underwater entry process of the navigation body and can be suitable for the buffering load reduction purpose of vertical or large-angle inclined underwater entry of the navigation body at the speed of 20m/s to 100m/s. The damping type buffering device is simple in structure and convenient to implement and install, and different hydraulicdampers can be adjusted or replaced according to actual working conditions and requirements to achieve the load reduction purpose of different degrees.

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...
