Abstract: A novel analytical formulation for aeroelastic analyzes using an accelerated, accelerated, effective, reduced-order aerodynamic modeling approach (PROM). In this approach, the eigenvalue problem of unsteady flows is defined based on unknown wake singularities. By constructing this reduced-order model, the quasi-static eigenmodes of the body are removed from the eigensystem and it is possible to obtain satisfactory results without using the static correction technique when using sufficient eigenmodes. For illustration
In the purposes of the present invention, numerical examples are presented which demonstrate the accuracy and efficiency of the present method over conventional reduced order modeling (CROM). Also, the incorporation of this aerodynamic model into the aeroelastic flutter model are shown. Stability results are presented for critical and non-critical velocities.
