Abstract

The invention provides a shaftless pump spraying vector propelling device. The propelling device is used for driving an underwater vehicle to sail and comprises a guide pipe, a hub fixedly arranged inthe guide pipe, an integrated motor rotor rotationally arranged in the guide pipe, an impeller integrated with the integrated motor rotor, a front guide vane arranged on the inflow side of the impeller and a steering mechanism arranged on the outflow side of the impeller and used for controlling steering of the underwater vehicle. The front guide vane and the steering mechanism are both connectedwith the hub. By means of the arrangement, the front guide vane and the steering mechanism are integrated, the problem that an existing shaftless pump jet propeller is poor in maneuverability is solved, meanwhile, appendages of an underwater navigation body can be reduced, reduction of navigation resistance of the underwater navigation body is facilitated, and the propelling device has wide application prospects.
