Abstract

The invention relates to a vector control device based on a water jet propeller, belonging to the technical field of the shipbuilding industry. The vector control device based on the water jet propulsion includes: a nozzle flange, a baffle, a baffle support, a rotating shaft, a direction control link, an executive link and a hydraulic drive assembly. The invention controls the rotation of the baffle plate through the hydraulic drive system, so as to achieve the purpose of precisely changing the water flow direction at the outlet of the water jet propeller, and then realizes the attitude control of the ship driving on the water surface. The flow velocity in the pipeline quickly determines the size of the baffle, and the operation is flexible and effective without affecting the overall direct flight speed.

Description

technical field [0001] The invention relates to a vector control device based on a water jet propeller, belonging to the technical field of the shipbuilding industry. Background technique [0002] The nozzle of the waterjet propulsion is used as the control surface of the ship, and the nozzle is required to be deflected according to the needs of the ship's navigation to generate the steering force and moment required to control the ship. The nozzle works under high pressure and high alternating loads. Since its birth, a lot of research has been done on various vector nozzle devices, mainly box-shaped nozzle devices and spherical nozzle devices. The box-shaped nozzle does not change the original fixed nozzle of the water jet propeller, but only installs a box-shaped rotating baffle box on the outside of the propeller, but the mechanical structure is complex, the weight is large, and the external contour is large; the spherical nozzle device adopts a spherical rotation adjustm...
