In this paper, the propeller unsteady aerodynamic and “propeller/wing” aerodynamic interaction are investigated using the Computational Fluid Dynamics (CFD) method. Based on the true three-dimensional (3D) propeller simulation, a steady RANS solution for ANSYS FLUENT was presented using an actuator-disk approach, with a user-defined function that was proposed for the commercial solver. The full 3D unsteady RANS numerical simulation work was performed using four models: (1) a clean wing with span length of 1 m; (2) single propeller model composed of four blades; (3) the “propeller/wing” model containing propeller and 1-m wing; (4) a clean wing with span length of 3 m. On the other hand, the actuator-disk model contains three models: one disk model, one disk/wing model, and two disk/wing models. The unsteady aerodynamic results revealed that propeller slipstreams affect the wing characteristics by changing the lift and drag. Meanwhile, when the freestream angle of attack is not equal to 0°, the distribution of the pressure coefficient of the blade is very different at various phase positions. Actuator-disk method can greatly reduce the calculation cost and provide satisfied prediction of the trends of the distributed propeller aerodynamic performance.
