Problems solved by technology

The main problem in this respect is that no matter adding the sliding board or the tail control surface, it will increase the resistance on the moving body. stability
These cavitator structures only change the force of the cavitator from one side, and can only change the maneuverability of the moving body from one channel

Abstract

The invention provides a maneuvering control and gas leakage inhibition type retractable cavitator structure and a multi-stage retractable cavitator. The cavitator structure comprises a hollow cavitator blade rotating shaft and a driving motor, the driving motor is arranged in a moving object, the cavitator blade rotating shaft is arranged on the outer surface of the moving object and provided with cavitator blade connection rings, retractable blades and nonretractable blades are in cross arrangement and hinged to the cavitator blade connection rings, and each nonretractable blade is provided with a small hole. Driving rods are uniformly arranged on the outer surface of a cylinder which is mounted at an output end of the driving motor, the driving rods penetrate the moving object and the cavitator blade rotating shaft to be mounted in the corresponding small holes, and the driving rods and the small holes are equal in quantity. By the maneuvering control and gas leakage inhibition type retractable cavitator structure and the multi-stage retractable cavitator, maneuvering navigation capability of the multi-phase flow moving object in water can be improved effectively.

Description

technical field [0001] The invention relates to a cavitator, in particular to a retractable cavitator structure for motor control and blocking gas leakage and a multi-stage retractable cavitator, belonging to the control and reduction of entrained gas in multiphase flow moving bodies in water technology field. Background technique [0002] The control technology under the condition of multiphase flow in water is an important key technology to improve and enhance the maneuverability of moving bodies in multiphase flow in water. For the moving body of multiphase flow in water, the control is mainly realized by the head cavitator rudder surface and the tail rudder surface. Since the tail rudder easily changes the flow stability during maneuvering, the head cavitator rudder is the main pitch and yaw control element. Correspondingly, in order to increase the speed of the flying body, the area of ​​the cavitator rudder surface is generally very small. From the way of control fo...
