Active vector thrusting method of three screw propellers

Abstract

The invention provides an active vector thrusting method of three screw propellers, comprising the following steps: (1) mounting three sets of screw propeller active vector thrusters on an underwater aircraft carrier (1), wherein the first and second screw propeller active vector thrusters (2,3) are transversely symmetrically arranged at the two wings of the underwater aircraft carrier (1); the third screw propeller active vector thruster (4) is arranged at the tail of the underwater aircraft carrier (1); and (2) realizing the forward moving, backward moving, turning, floating upward, submerging, yawing, pitching, underwater suspending, lateral translating and controllable rolling of the underwater aircraft by operating the three sets of screw propeller active vector thrusters. The invention greatly simplifies the thrusting system of the underwater aircraft, has strong portability, practicality, simple structure, smooth outline and low cost.

Description

technical field

[0001] The invention relates to a propulsion method of an underwater vehicle, in particular to a three-propeller active vector propulsion method. Background technique

[0002] At present, the propulsion methods of relatively mature underwater vehicles developed at home and abroad generally use multiple propellers for coordinated control to obtain the control force and torque of the carrier to realize maneuvers such as forward, backward, and turn of the underwater vehicle. action. If the underwater vehicle is expected to achieve maneuvers such as floating, diving, and pitching, it is necessary to add a control rudder or a propeller propulsion device. Excessive configuration of propeller propellers or the introduction of control rudders will increase the navigation resistance while improving the navigation maneuverability of the carrier. Moreover, when the propeller of some aircraft is not in use, it may become a resistance or even an obstacle to navigation, ...
