Projectile support capturing and projectile support and projectile body separating device for high-speed underwater launching equipment

Abstract

The invention discloses a projectile support capturing and projectile support and projectile body separating device for high-speed underwater launching equipment, and belongs to the technical field of ship and ocean engineering. According to the projectile support capturing and projectile support and projectile body separating device, the problems that in an existing high-speed water entry experiment of a high-pressure gas launched projectile body, a launching tube continues to eject high-pressure gas after the projectile body enters water, and the free surface and cavitation evolution characteristics of the water entry phenomenon are greatly influenced are solved, and the problems that in the high-speed water entry launching process of the projectile body, due to collision between a projectile support and a projectile support catcher, the deflection of the projectile body is prone to be caused, a water entry experiment result is influenced, and even launching failure is caused are solved. One end of a spring container is coaxially and fixedly connected with one end of the launching tube, the other end of the spring container is coaxially and fixedly connected with a guider, a projectile support stopper is coaxially installed in the launching tube in a penetrating manner, one end of the projectile support stopper is clamped at one end of the launching tube, the projectile support stopper is of a cylindrical structure, and a projectile body guide tube is sequentially and coaxially installed in the guider and the spring container in a penetrating manner; and one end of the projectile body guide pipe is fixedly connected with the projectile support stopper.

Description

technical field [0001] The invention relates to a bullet holder capture and bullet holder separation device for high-speed water-entry launch equipment, which belongs to the technical field of ships and marine engineering. Background technique [0002] The 21st century is called the century of the ocean. As an important part of maritime military power, underwater weapons are of great significance to maintaining and competing for maritime sovereignty. Underwater weapons will not only cause partial damage to the ship, making it incapable of combat, but even cause the ship to break and completely lose its vitality in severe cases. Under the new international situation, it is very important for our country to develop naval underwater weapons and equipment. When the underwater weapon is launched into the water from the air, the high-speed cross-media problem of the projectile has brought great difficulties to the numerical simulation due to the high-speed impact problem, multi-...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the problem that in the existing high-pressure gas launch projectile high-speed water entry experiment, the launch tube will continue to spray high-pressure gas after the projectile enters the water, which greatly affects the free surface and cavitation evolution characteristics of the water entry phenomenon, and the high-speed water entry of the projectile. During the process, because the collision between the bullet holder and the bullet holder catcher interferes with the movement of the projectile body, it is very easy to cause the deflection of the projectile body, affect the results of the water entry experiment, and even cause the problem of launch failure. The bullet rest capture and bullet rest separation device of the equipment
