Abstract : A method is presented for the determination of the effect of boundary layer on the unsteady pressure distributions on an oscillating body in continuum hypersonic flow. The method is based on the concept of dynamic viscous pressure interactions, which takes into account the relative motion between the body surface and the boundary-layer displacement surface. The method can be applied to arbitrary bodies and flow conditions, provided the relevant inviscid unsteady pressure distributions and the dependence of the boundary-layer displacement on the steady flow variables are known. In its present version the method is limited to low-frequency and small-amplitude oscillations. (Author)
