Abstract

Some preliminary work on the application of CFD to rapid manoeuvre and dynamic flight is presented. A method for transient CFD calculation with arbitrary trajectories, and its implementation, is presented. We establish validity of the method in near-incompressible flow, using comparison with analytical solution of flow around a rotating cylinder. In a second test case, we consider pitching moments of a turning airfoil at different angular velocities, and offer a simple mean-line analysis for comparison. Finally, we illustrate movement of strake-generated vortices compatible with the concept of an effective angle of attack in turns.
