Post-Stall Prediction of Multiple-Lifting-Surface Configurations Using a Decambering Approach
2004
42nd AIAA Aerospace Sciences Meeting and Exhibit
unpublished
A novel scheme is presented for an iterative decambering approach to predict the post-stall characteristics of wings using known section data as inputs. The new scheme differs from earlier ones in the details of how the residual in the Newton iteration is computed. With earlier schemes, multiple solutions are obtained for wings at high angles of attack as the final converged solution depends on the initial conditions used for the iteration. With this scheme, multiple solutions at high angles of
