Marine prepositive vector propulsion system

Abstract

The invention relates to a marine prepositive vector propulsion system, which includes a left thruster part and a right thruster part which are composed of respective propellers and protective shellscorrespondingly. The left thruster part and the right thruster part are mutually connected and arranged in axial symmetry. The propulsion system is installed in front of the center of gravity of a ship under the middle of a hull, and the propulsion direction has certain included angles with the directions of the horizontal plane and the vertical plane of hull operation correspondingly. During operation, the left thruster and the right thruster of the propulsion system are controlled to work and stop correspondingly, in addition to achieving the basic propulsion performance, special maneuvers such as in-situ rotation and 90-degree sharp rotation can further be achieved, the ship steering flexibility and resistance to severe wind and waves are improved, and meanwhile, the propellers of the thrusters are prevented from being damaged.

Description

technical field [0001] The present invention relates to ships, warships or other water craft, and in particular to a front vector propulsion system used on unmanned ships / boats. Background technique [0002] An unmanned ship is a fully automatic surface robot that can navigate on the water according to preset tasks with the help of precise satellite positioning and its own sensing. It is used to assist humans in obtaining a large amount of ocean data. [0003] An unmanned ship usually includes a hull, control system and propulsion system. Compared with other traditional ships, due to the small size and light weight of unmanned ships, they are easily affected by waves and winds and change their course when driving in the sea. Existing propulsion systems generally use traditional marine rear propellers as propellers. Although the effect of the rear propeller can improve the utilization efficiency of the propeller and reduce the propulsion resistance, so that the ship can rea...

AI Technical Summary

Problems solved by technology

Although the effect of the rear propeller can improve the utilization efficiency of the propeller and reduce the propulsion resistance, so that the ship can reach a high speed, the rear propeller is relatively weak in steering flexibility as a propeller, and its ability to resist wind and waves is poor.
