Description

Technical Field

[0001] The present invention relates to the technical field of underwater launching experiments on navigating bodies, and in particular to a horizontal motion simulation experiment device and method for an underwater ejection system. Background Art

[0002] The underwater ejection system is an important system, and it is very necessary to study the mechanism of underwater launching. This kind of research helps to better understand the movement law of missiles underwater and improve their accuracy and effectiveness. Therefore, it is of great significance to carry out research on the mechanism of underwater missile launching. The model experiment method is a research method with high efficiency and low investment. The experimental method is often used in the study of the mechanism of navigation body out of water. Therefore, it is very important to build a set of experimental systems that can truly simulate the ejection of underwater navigation body out of water.

[0003] In real situations, when a projectile is launched from a vehicle, the vehicle often has lateral movement. This movement provides a radial velocity for the projectile, which will cause the projectile to deviate from the vertical motion trajectory and produce lateral involved motion. How the lateral velocity affects the result, how big the impact will be, and whether it will cause the projectile to fail to exit the water. There is little public information on this aspect of research, which is of great significance. In summary, when conducting underwater ejection of a navigation body out of the water, it is necessary to simulate the lateral movement of the vehicle, so it is necessary to build a set of experimental equipment with the ability to simulate horizontal movement.
