Specific embodiment
In the following description, a large amount of concrete details are given so as to provide a more thorough understanding of the present invention.So
And it is obvious to the skilled person that the present invention may not need one or more of these details and be able to
Implement.In other examples, in order to avoid confusion with the present invention, for some technical characteristics well known in the art not into
Row description.
In order to thoroughly understand the present invention, detailed step and detailed structure will be proposed in following description, so as to
Illustrate technical solution of the present invention.Presently preferred embodiments of the present invention is described in detail as follows, however other than these detailed descriptions, this
Invention can also have other embodiments.
The purpose of the design is to release a kind of propulsion system of new model, which can be to avoid many prior arts
The drawbacks of, to obtain more excellent performance.Have in the existing mainstream propeller progress of work such as following insufficient: firstly, its leaf
Piece generates the pressure difference of blade back and blade face, to form thrust, due to three-dimensional airfoils effect, this pressure difference be will lead in the blade tip
Portion, which generates, to be streamed, and upsets flow field to make aerofoil profile no longer keep good characteristic；Secondly as the blade section at more than half path position
Bigger thrust is generated at small radii position, is distributed in biggish power on blade and is produced longer torque, it is unfavorable to intensity；
Again, high speed marine diesel need to be equipped with reduction gearbox to complete the transmitting of torque and drive the propeller to slowly run, cumbersome
It is inefficient, without reduction gearbox low-speed marine diesel engine due to stroke it is larger and cause sufficiently bulky, be unfavorable for arranging；In addition,
After conventional propeller is often placed in ship, the interference by hull is obvious, and propeller is the machinery to rotate in a circumferential direction, but works in week
Into non-uniform flow field, this is obviously also unfavorable；In addition, for axis drive-type propeller, since its thrust is contributed
Mainly from more than half path position blade section, therefore its blade must extend to blade tip from blade root, inflexible；Finally, for answering
To burst operating condition, propeller is changed to reversing process from positive vehicle, and axis drive-type propeller will cope with biggish torque, this is to the strong of axis
Degree requires very high.
