主　　题：Surface circulation distribution Unsteady actuator disk model Blade tip vortices reproduction 

摘      要：The actuator disc method is an engineering approach to reduce computer resources in computational fluid dynamics(CFD)simulations of helicopter rotors or aeroplane *** of an actuator disc based on rotor circulation distribution allows for approximations to be made while reproducing the blade tip *** circulation distributions can be formulated according to the nonuniform Heyson-Katzoff“typical loadin *** forward flight,the nonuniform disk models include“azimuthalsin and cos terms to reproduce the blade cyclic *** azimuthal circulation distribution for a forward flight mode corresponds to trimmed conditions for the disk rolling and pitching *** amplitude of the cos harmonic is analysed and compared here with presented in references data and CFD simulations results.
