Unsteady Interactions of Transonic Airfoils with Gusts and Concentrated Vortices,
Abstract
Unsteady interactions of strong concentrated vortices, distributed gusts, and sharp-edged gusts with stationary airfoils have been analyzed in two-dimensional transonic flow. A simple and efficient method for introducing such vortical disturbances has been implemented in numerical codes that range from inviscid, transonic small-disturbance to thin-layer Navier Stokes. The numerical results demonstrate the large distortions in the overall flow field and in the surface air loads that are produced by various vortical interactions. The results of the different codes are in excellent qualitative agreement, but, as might be expected. the transonic small-disturbance calculations are deficient in the important region near the leading edge.
