Based on momentum theory and the results of numerical simulation with full propeller blade modeling, a new actuator disk modeling of airplane propeller is presented. Sections 1 and 2 of the full paper explain our approach mentioned in the tittle, which we believe is new and effective and whose core consists of: (1) the full propeller blade modeling is used to numerically simulate propeller slipstream; (2) the pressure jump of propeller disk is got from the results of the numerical simulation and a pressure jump curve is obtained; (3) the actuator disk model with the pressure jump curve is constructed to numerically simulate propeller slipstream. Setion 2 also evaluates our approach; the simulation results, presented in Figs.9 and 10, and their analysis show preliminarily that the actuator disk model can indeed numerically simulate effectively the main characteristics of propeller slipstream.
