A supercavitation experiment generating device for variable-angle launch of a submarine-launched vehicle

Abstract

The invention discloses a supercavitation experiment generating device capable of launching a submarine launched navigation body in a variable angle mode. The supercavitation experiment generating device comprises a launching component used for launching the navigation body in an obliquely upward mode, a water box component and a lifting rotating component used for adjusting the angle and the height of the launching component. A high-pressure air source sequentially passes through a high-pressure cylinder, a cylinder valve connector and an electromagnetic valve and then is connected with a tube valve connector, and a launching tube is connected to the tube valve connector in a sealing mode. A ball valve is mounted on one downward tilting side face of a water box, and a water box cover which can slide horizontally is arranged on the water box. The high-pressure cylinder is fixed on a first base, the first base is hinged to a second base, and the first base is fixed on the second base through an arc rotating mechanism. A lifting mechanism is connected between the second base and a third base. By means of the supercavitation experiment generating device, launching of different angles and depths can be achieved, water external launching can be achieved at the same time, the condition that water enters the launching tube, so that resistance is increased is avoided, and thus an experiment basis is provided for studying supercavitation generation of the submarine launched navigation body.

Description

technical field [0001] The invention relates to a supercavitation experiment generator, in particular to a supercavitation experiment generator for variable-angle launch of a submarine-launched vehicle. Background technique [0002] Cavitation bubble is the phenomenon of gasification or vaporization of liquid flow under certain pressure and temperature. When the relative speed of the underwater vehicle and the surrounding liquid increases, the pressure around the vehicle will decrease; when the speed increases to a certain level, the pressure of part of the water body will be lower than its saturated vapor pressure, and thus become a vapor state, which is called air. phenomenon. With the continuous increase of the speed of the flying body, the cavitation keeps increasing, and when the cavitation wraps the whole flying body, a supercavitation is formed. In the early days, due to cavitation corrosion, people always wanted to avoid cavitation. However, in the 1960s, scientist...

AI Technical Summary

Problems solved by technology

For angled water launch, if the launch tube is deep into the water, water will enter the launch tube, which will increase the resistance and make it difficult to produce supercavitation; most of the current supercavitation launch devices are vertical launch and angled water launch. It is not easy to accurately adjust the angle range of the water launching device
