  1. (, International Forum on Aeroelasticity and Structural Dynamics)
    A cantilevered plate at an angle of attack in axial high speed flow represents a prototypical control surface. Using a computationally efficient modal structural model cou- pled with a novel enhanced piston theory aerodynamic method, a nonlinear aeroelastic model is developed. Results presented include pre-flutter stable steady state solutions, flutter points, and post-flutter limit cycle oscillations. Because of the computationally efficient methodology, many simulations can be run to define sensitivities to mathematical modeling, model parame- ters, and numerical methods.
