Asymmetrically changing rotating blade shape (ACRBS) propeller and its airplane and wind turbine applications |
摘要 |
A propeller includes a plurality of propeller blades. Each blade has an adjustable drag coefficient. A plurality of actuators adjusts the drag coefficients of the propeller blades. A controlling unit controls the plurality of actuators such that the drag coefficients of each propeller blade is adjusted according to a pattern that is dependent upon the rotational angle of the particular propeller blade so that the drag of each propeller blade is maximized at the same point through a course of revolution and minimized throughout the remainder of that revolution.
