Abstract

The invention relates to a supercavitation experimental device, in particular to a vehicle underwater launching experimental device for supercavitation mechanism research. The vehicle underwater launching experimental device for supercavitation mechanism research comprises a pneumatic launching system, a launching system supporting device, a water tank and an observation and recording system, wherein the launching system supporting device is placed on one side of the water tank provided with an electric knife gate valve; the pneumatic launching system is fixedly arranged on the launching system supporting device; and the observation and recording system is placed on one side of the water tank provided with an acrylic plate. The vehicle underwater launching experimental device for supercavitation mechanism research can truly reflect the supercavitation phenomenon, and further changes the launching speed of the vehicle by changing the air pressure set value of the high-pressure air cylinder of the pneumatic launching system, thereby realizing the supercavitation mechanism research of vehicles with different speeds; by replacing pipe valve connectors and launching tubes with differentinner diameters of the pneumatic launching system, the vehicles with different sizes can be launched, and the supercavitation mechanism research of the vehicles with different sizes can be realized;and by replacing the vehicles with different shapes of the pneumatic launching system, the supercavitation mechanism research of the vehicles with different shapes is realized.

Description

technical field [0001] The invention relates to a supercavitation experiment device, in particular to an underwater launch experiment device for a vehicle used for supercavitation mechanism research. Background technique [0002] When the vehicle sails at high speed underwater, the tiny air cores on its outer surface expand rapidly under the action of local low pressure, forming a large number of visible bubbles. When these bubbles completely wrap the vehicle and close the fluid domain behind the stern of the vehicle in an ellipsoidal shape, it is called supercavitation. When the flying body is in the supercavitation state, the fluid in contact with it has been vaporized. Since the density of water vapor is much smaller than that of air, the supercavitation phenomenon can greatly reduce the navigation resistance and greatly increase the speed of the flying body. Therefore, the supercavitation The study of cavitation mechanism is of great significance to the development of my...
