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 technology
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
To reach saturated vapor pressure at such a temperature cavitation phenomenon finally occurs for the formation for leading low-pressure area.But under field conditions (factors)
It is extremely harsh to generate the natural supercavitation condition with drag-reduction effect, needs cavitation number to be less than 0.1 i.e. headway and is more 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, increase 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 mechanical characteristic having the same of the natural supercavitation 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 by these devices itself can hardly be realized around its own
Central axes rotate.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 disadvantage that：1, it is only capable of realizing that cavitation device spin, sail body itself can not spin.2、
There is no rational sealing structure, it may occur that gas and water leakage.
