Abstract : A computer program for the analysis of wing-body combinations in subsonic flow is described. The configuration is represented by a large number of surface panels. The circulation about lifting surfaces is provided by a system of vortex lattices. The strengths of the sources and vortices which satisfy the boundary condition of tangential flow for a given Mach number, angle of attack, and/or angle of yaw are determined by solving a system of linear equations by an iterative procedure. The program computes the pressure coefficients at the panel centroids and integrates these pressures numerically to obtain the lift, drag, and pitching moments.
