| Abstract: | Aerodynamic characteristics of autorotating rotor were researched by way of theory and experiment.An aerodynamic model of autorotating rotor was established through numerical integral method based on blade element theory,and dynamic inflow theory was introduced into this model.The aerodynamic distributions and the influence of various design variables on the performance of autorotating rotor were studied and analyzed.Test model and experiment project were developed and designed.The theoretical predictions were validated by wind tunnel tests.Some phenomena were discovered in the course of test such as minimum wind speed rule and minimum pre-rotation rev rule. |
