Abstract

The invention discloses a multi-mode water-entry experiment launching device, which belongs to the technical field of fluid mechanical engineering. The invention includes a power device system, a sliding system, an attack angle adjustment measurement system, a water entry speed measurement system, a pitch angle adjustment system and a pitch angle measurement system. The experimental object is a structure. The power plant system provides the kinetic energy for the angle of attack adjustment measurement system to slide forward on the slide rail. The angle of attack adjustment measurement system is used to adjust the rotational speed of the structure entering the water, and visually adjust the angle of attack into the water. The pitch angle measurement system reads the water entry pitch angle in real time through the dial. The invention can simulate multi-mode water entry experiments, and has the following functions: (1) realize the rotating water entry with adjustable speed of the structure; (3) It can adjust and accurately measure the speed of the structure at the moment of launch; (4) It can be applied to the launch experiment of various structures into water.

Description

technical field [0001] The invention belongs to the technical field of fluid mechanical engineering, and in particular relates to a multi-mode water entry experiment launching device. Background technique [0002] The water entry problem is a classic problem in hydrodynamics, involving solid-liquid-gas three-phase interactions. The problem of water entry has an important relationship with many engineering applications and natural phenomena, such as: air-dropped missiles, ditching, ship slamming, water drifting, ricocheting, etc. Especially in military applications, cross-media naval warfare weapons that can repeatedly cross the water-air interface have gradually attracted widespread attention due to their high anti-reconnaissance characteristics and penetration capabilities. The vehicle needs to maintain the ballistic and attitude stability during the skid-jump process and the water entry process. When the water-launched vehicle interacts with the water surface, due to the ...
