Description
Technical field
The present invention relates to a kind of supercavity experiment generating means, especially relate to the supercavity experiment generating means that a kind of latent variable-angle penetrating sail body is launched.
Background technology
Cavitation bubble be liquid flowing certain pressure and at a temperature of occur gasification or vaporization phenomenon.When underwater sailing body increases with surrounding liquid speed of related movement, sail body ambient pressure will reduce；When speed increases to a certain degree, the pressure of part water body will be less than its saturated vapor pressure, is accordingly changed into steam state, referred to as cavitation phenomenon.Along with being continuously increased of sail body speed, cavity constantly increases, and just forms supercavity after whole sail body is wrapped up by cavity.In early days, due to cavitation corrosion, cavitation phenomena always people want to avoid, but in the sixties in 20th century, former Soviet Union scientist finds, when the speed of moving object brings up to a certain degree, body surface can be surrounded by one layer of bubble, i.e. produces " supercavitation phenomenon ".Now, the resistance of water can be substantially reduced, and bubble also will not produce impact because of explosion to surface of moving object.Hereafter, research worker finds that sail body frictional resistance in water is about 850 times of resistance in air, and the frictional resistance that the application of supercavity technology can make underwater sailing body significantly reduces.This property of reduction drag of supercavitating vehicle is widely used in military and national defense technology.
