发明名称 Tool and Method for Rapid Design and Reduction of Rotor Mass
摘要 Wind turbine rotors are designed by means of computationally intensive algorithms, simulation tools and various models. These art methods, however, have not been successful in relating the blade mass directly to the aerodynamic, rotational dynamics and material parameters. Consequently, modelers are often grappling with discrepancies and ambiguities. Prior art generally constructs the empirical relation MR∝Rνwhereνis given a value that ranges between 1.8 and 3, depending on who, and how the experimental data is presented and compared with theoretical or simulation results. The present invention derives for the first time a precise scaling law that relates the blade mass to the cubic power of R exactly. It is based on using a novel tool in the form of a set virtual air gear teeth that intermesh with the blade gear teeth, to link the actuator disc to the rotational dynamics and material properties of the blades.
