Abstract : The paper describes a very general method for determining the unsteady, two-dimensional, incompressible flow about one or more bodies of arbitrary shape. Specifically the surface pressure, forces and moments are obtained for bodies oscillating with small amplitude about their steady equilibrium position and on bodies in small amplitude gust fields. The equilibrium configuration of the bodies may also be arbitrary. Calculated results for single bodies in and out of gust fields are compared to results obtained by existing methods. Calculations and comparisons are also presented for two interacting bodies. (Author)
