An underwater vector propulsor for flexible steering using the Coanda effect

Abstract

The present invention relates to an underwater vector propeller utilizing Coanda effect to realize flexible steering. Partition plate; the main propulsion motor is installed in the main propeller flow channel; the vector motor has a propeller; the housing is connected to the main propeller flow channel through the partition plate and the space is the main channel; the attached flow channel is A channel formed by the inner wall structure of the casing; the attached flow channel connects two symmetrical main flow channels; vector motors are provided in the main flow channels; both ends of the casing are opening structures. Its advantages are as follows: a kind of underwater vector thruster which utilizes Coanda effect to realize flexible steering of the present invention, when ships, submarines, underwater unmanned robots, etc. need to turn, vector propulsion can be realized by changing the speed of different vector motors , to achieve more flexible propulsion control underwater.

Description

technical field [0001] The invention relates to a novel underwater vector thruster, in particular to an underwater vector thruster which can realize flexible steering and is applied to various ships, submarines, torpedoes, and underwater unmanned robots. Background technique [0002] At present, human beings are facing three major problems of population, resources and environment. Among them, the natural resources consumed by human beings are decreasing day by day, which makes people start to explore the ocean, which covers two-thirds of the earth. Resources and petroleum resources, in recent years, countries all over the world are stepping up research and development of marine resources. Its marine detection equipment is an important tool for seabed detection. Therefore, marine detection equipment such as ships, submarines, torpedoes, and underwater drones have emerged as the times require. [0003] With the continuous development of the offshore industry, especially the ...

AI Technical Summary

Problems solved by technology

Low thrust vectoring, especially when the vehicle turns and its thrust is lost

[0004] In addition, due to the complex situation on the seabed and the harsh environment, the requirements for the maneuverability of underwater robots are extremely high. Most underwater robots cannot fully meet the above action requirements

In order to change the propeller propulsion mode of the underwater robot, the direction of the propulsion force can be changed by relying on the rudder. The propulsion force can only be changed in one direction of rotation. When the underwater robot needs to change the depth and the forward course; The rudders in the two directions of the wing and the vertical wing are controlled, and the flexibility of movement is greatly limited

[0005] Secondly, in order to improve flexibility and maneuverability, it is also designed to install multiple propeller propellers on the underwater robot, which are respectively arranged around the underwater robot, but this method will increase the complexity of the mechanical system and increase the cost. , and some propellers will only start when the underwater robot turns, and most of them are idle under normal circumstances, resulting in a waste of resources

[0006] In summary, there is an urgent need for an underwater vectoring thruster that can realize flexible steering, simple structure, and low manufacturing cost, and there is no report about this underwater vectoring thruster
