Abstract:

The objective of this proposal is to develop efficient CFD based techniques for the prediction of wing rock amplitudes for a delta wing-body. These methods, based on either a centre manifold projection or the method of matched scales, use information obtained from the direct calculation of instability onset to produce a small order system of equations which can predict the limit cycle response for values of the bifurcation parameter near the onset value. The successful demonstration of these techniques for large order systems and in a robust fashion would be unique.
