Tail cover separating mechanism suitable for high-speed water entry

Abstract

The tail cover separation mechanism comprises a first separation tail cover and a second separation tail cover, and the first separation tail cover comprises a first cover body, a first limiting ring, a first annular supporting piece and a first connecting lifting lug; the first cover body is semi-cylindrical; the first limiting ring is positioned at the front end of the first cover body and is integrally connected with the first cover body; the first limiting ring is in transition fit with a limiting clamping groove in the tail of the navigation body, and the first limiting ring is connected with the limiting clamping groove through a first explosive bolt; the first annular supporting piece is installed in the first cover body. The first connecting lifting lug is fixed at the tail end of the first cover body; the second separation tail cover and the first separation tail cover are the same in structure, the second separation tail cover and the first separation tail cover are installed at the tail of the navigation body in a matched mode, and key components such as a tail vane and a propeller of the navigation body can be effectively protected when the navigation body is impacted by tail beating force in the water entering process.

Description

technical field [0001] The invention relates to the technical field of protection devices for the tail of a vehicle, and more specifically relates to a tail cover separation mechanism suitable for high-speed water entry. Background technique [0002] Due to the initial disturbance during the high-speed entry of the vehicle into the water, the force on the vehicle is unbalanced, which will produce a large moment step change, and the process of the vehicle's entry into the water is accompanied by a large attitude angular velocity, thereby forming a tail beat phenomenon. When the tail beat occurs, the tail of the vehicle hits the interior of the cavity, and after the impact, the vehicle damps and oscillates and tends to be stable, or it periodically hits the upper and lower walls of the cavity alternately, and maintains dynamic stability during the continuous impact. Stability has a positive effect to a certain extent. [0003] However, the tail beat phenomenon has high requir...
