Dynamics of Aerospace Vehicles -- Nonlinear Flight Mechanics

The unsteady aerodynamics due to vortex breakdown are studied, with application to a 65-degree delta wing. At high angles of attack, the flow field response to changes in attitude contains multiple time scales. Furthermore, severe nonlinearities are present which further complicate aerodynamic model...

Zusammenfassung:The unsteady aerodynamics due to vortex breakdown are studied, with application to a 65-degree delta wing. At high angles of attack, the flow field response to changes in attitude contains multiple time scales. Furthermore, severe nonlinearities are present which further complicate aerodynamic modeling. The implications for wind tunnel testing and aerodynamic modeling are discussed.
