Abstract

A new model for the dynamic wake distortion effects for maneuvering and transitional flight from hover,involving the wake skew,the wake longitudinal and lateral curvatures and the wake spacing as additional states,has recently been developed. The associated time constants of the model have been extracted from the vortex tube analysis. The new model is integrated with a generic helicopter flight simulation model. Correlations with the Black Hawk helicopter flight test data are used to study the effect of the wake curvature parameter on simulation fidelity for maneuvering flight. Also,analytical and numerical comparisons are made between the new model and the augmented dynamic wake distortion inflow model proposed by Keller et al.
