Abstract : A review is made of a method for computing the aerodynamic influence coefficients (AICs) for surfaces with supersonic leading edges. The method is based on the two-dimensional secondorder potential solution of Van Dyke. The strip oscillatory coefficients are obtained from the extension of Van Dyke's work by Rodden and Revell to include the effects of sweep and finite span in addition to the effects of thickness, leading to a method that will avoid the unconservation of linearized theory and will be applicable at Mach numbers below the lower Mach number limit of piston theory. The influence coefficients relate the aerodynamic forces to the surface deflections. The program capacity is 25 surface strips, 25 values of Mach number, and 50 values of reduced velocity.
