The unsteady Vortex-Lattice Method has been used successfully used for these cases, but it lacks the ability to model leading-edge stall. This work shows the development of an expanded UVLM, capable of predicting leading-edge vortex shedding. The model is validated against experimental wind-tunnel test results for prescribed movement and Limit-Cycle Oscillations on a flat plate.
