Abstract: In calculating rotor aerodynamics and velocity field by using free wake theory, it is the key to determine the wake geometry structure. A new free wake method is developed to calculate the convergent wake structure and blade aerodynamic load distribution. Computation results are compared to the experimental data. The well coincidence shows that the method is correct.
