Abstract : The analysis of the forces on a body released from an aircraft is separated into two categories: The analysis of the flow around a wing; and the analysis of a body in a non-uniform flow field. The flow around a wing was determined using a vortex lattice on a flat plate wing with constant sweep angles. The body was modelled by an ellipsoid of revolution forebody, and a paraboloid of revolution afterbody. The axial flow velocities were determined by using slender body theory for axial flow, except in the region of the blunt nose and tail. The cross flow velocities, and the axial flow velocities near the nose and tail were determined by computing the flow around spheres tangent to the body at every control point. Drag was simulated for potential theory by artificially accelerating the flow on the leeward side of the spheres.
