Abstract:

The unsteady transonic small perturbation differential equation is converted into an integrodifferential equation by application of the classical Greens function method. It is shown that no contribution form sock waves explicitly appears in this integral equation, due to the shock capturing properties of the Greens function method. After assuming that the motion consists of small infinitesimal perturbations around a thin nearly-planar body, a simplified integral equation for the streamwise velocity component is obtained, which is suitable for fast numerical computations.
