Abstract: In this paper,the Green's function method for steady aerodynamics is incorporated into the leading edge suction analogy for high α aerodynamics of slender wings,with the effects of vortex breakdown considered.The computational results agree well with experimental data. Thus, a rapid and exact enough aerodynamics algorithm is presented for the preliminary design of high performance aircraft.
