Description
Technical field
The invention belongs to the water tunnel experiment research fields of supercavitating vehicle, and in particular to a kind of for the logical of water tunnel experiment
Gas supercavitating vehicle rotation test device.
Background technique
Supercavity is one of the effective way that underwater high-speed navigation body realizes drag reduction.The origin cause of formation of supercavity is that lift-off is streamed and lured
The formation of low-pressure area is led, to reach saturated vapor pressure at such a temperature, cavitation phenomenon finally occurs.But under field conditions (factors)
Generating has the natural supercavitation condition of drag-reduction effect extremely harsh, and needing cavitation number less than 0.1, i.e. route speed is greater than 50m/
s.According to the definition of cavitation number, when fluid density is constant, reducing cavitation number, there are three types of basic skills: 1, increasing and carry out flow velocity
Degree, 2, reduce incoming-flow pressure, 3, increase vacuole in pressure.So increasing the water of pressure in vacuole using the method for artificial ventilation
Hole test method becomes a kind of main stream approach for studying supercavitating vehicle under experimental conditions.The ventilation that the method generates is super
Vacuole and the natural supercavitation mechanical characteristic having the same under identical cavitation number.
Existing all types of water tunnel experiment devices are concentrated mainly on the cavitation device type of research sail body and sail body exists
Mechanical property under the different angles of attack or yaw angle, and sail body involved in these devices itself can hardly be realized around its own
Central axes rotation.Under the conditions of only only a few patent realizes and realizes water tunnel experiment in this function, such as CN205192722U
The spin of cavitation device, but this device has the following disadvantages: 1, is only able to achieve cavitation device spin, and sail body itself can not spin.2,
There is no reasonable sealing structure, it may occur that gas and water leakage.
