In order to analyze the comprehensive influence of a compound leading edge flap (LEF) and trailing edge flap (TEF) on the rotor aerodynamic characteristics of a 2-D airfoil and a 3-D rotor, a grid generation method including the LEF/TEF is developed. Based on the Navier–Stokes equation, a high-precision analysis method of aerodynamic characteristics under compound deflected LEF/TEF is established. Through a numerical analysis, variations of the aerodynamic characteristics under different LEF/TEF deflection states are studied and the effects of compound flap deflections on the leading-edge vortex and shock wave in 2-D and 3-D cases are investigated thoroughly. The results indicate that the LEF deflects downward and the range of the leading-edge vortex decreases; the pressure distribution on the leading edge of airfoil with differently deflected TEF is nearly identical at a large Mach number. The effect of the compound deflected LEF/TEF on the aerodynamic characteristics is approximately equivalent to the superposition of the separate deflection effects of the LEF/TEF.
