| Abstract: | Based on the potential theory,a linearity combination of the disturbance flow field generated by the uncompressible vortex part was applied in the computation of separate vortex flow.As the computation of single wing-surface,combined wing-surfaces and FC-1 aircraft showed,this low speed and high AOA aerodynamic computing method given in this paper is effective in the range of stall AOA. |

| Keywords: | AOA potential flow separated flow nonlinear |
