Problems solved by technology
[0004] However, for the propeller of the full-turn ducted rudder propeller, since the full-turn ducted rudder propeller can rotate 360° in all directions, the test period is long and the design cost is high during the dripping test, which makes the design of the propeller Low efficiency, unable to meet the requirements of rapid manufacturing

The invention discloses a design method of a propeller, and belongs to the field of blade design. The design method comprises the steps that input parameters are determined, geometric parameters are obtained through calculation according to the input parameters, and the geometric parameters comprise the rotating speed of a propeller, the disc surface ratio of the propeller, the average pitch of the propeller and the pitch, chord length, skew and maximum section thickness of the propeller at different blade heights; establishing a geometric model of the propeller according to the geometric parameters; performing optimization simulation on the geometric model to obtain a plurality of groups of output parameters, the output parameters including thrust and torque of the full-rotation ducted steering oar when the propeller is at different rotating speeds; performing performance analysis on the geometric model according to the output parameters to obtain design parameters; and designing the propeller according to the design parameters. By means of the design method, the design period of the full-rotation guide pipe type propeller can be shortened.
Description
technical field [0001] The disclosure belongs to the field of propeller design, and in particular relates to a design method, device and equipment of a propeller. Background technique [0002] The propeller is the core component of the full-turn ducted rudder propeller. The full-turn ducted rudder propeller mainly generates thrust through the rotation of the propeller, thereby propelling the ship to sail. Compared with traditional rudder propellers, full-turn ducted rudder propellers can rotate 360° in all directions. Therefore, the blades of full-turn ducted rudder propellers also have underwater appendages that do not exist in conventional rudder propellers, that is, in rudder propellers, not only Only the propeller is located underwater, and other structures are located underwater, which requires more factors to be considered in the design of the blades of the full-turn ducted rudder propeller. [0003] In the related art, the design method of the blade of the full-turn...
