Abstract
A method controlling a thruster of a marine vehicle is provided. The marine vehicle is at least partially submerged in a liquid and includes a body and a thruster including two propellers. Each propeller includes blades intended to tum about a rotation axis of said propeller. The method includes a step of low-speed maneuver controlling, during which the thruster is controlled in such a way that each propeller generates a flow directed toward the flow generated by the other propeller and reaching the flow generated by the other propeller.
Claims18
A method for controlling a thruster of a marine vehicle at least partially submerged in a liquid comprising a body and the thruster, the thruster comprising two propellers, each propeller comprising blades intended to turn about a rotation axis of said propeller, the method comprising:
- maneuver controlling, during which the thruster is controlled in such a way that each propeller generates a flow directed toward the flow generated by the other propeller and reaching the flow generated by the other propeller,
- and wherein the distance between the propellers lies between a non-zero threshold distance and triple the diameter of a larger of the two propellers.
A control device to control a thruster of a marine vehicle at least partially submerged in a liquid comprising a body and the thruster the thruster comprising two propellers, each propeller comprising blades intended to turn about a rotation axis of said propeller, the control device being configured to implement a method comprising maneuver controlling, during which the thruster is controlled in such a way that each propeller generates a flow directed toward the flow generated by the other propeller and reaching the flow generated by the other propeller, wherein the control device comprises:
- a control member which, when receiving a setting for implementing maneuver controlling, is configured to calculate a configuration in which the thruster must be placed in order that each propeller generates a flow directed toward the flow generated by the other propeller and reaching the flow generated by the other propeller, and
- an actuator configured to control the thruster so as to place it in said configuration,
- wherein a distance between the two propellers lies between a non-zero threshold distance and triple the maximum diameter of the propellers.
