Abstract: A robust iterative method suitable for the numerical simulation of vortex flows at high angles-of-attack is established based upon the multiple line-vortex model (MLVM). Converged solutions of vortical flows over bodies of revolution for angles of attack up to 60° are obtained. Calculated values of the aerodynamical loads on a tangent-ogive forebody compare well -with experimental data.

Key words: high angle of attack, vortical flows, iterative method.
