Current methods for prediction and minimization of lift-induced drag at supersonic speeds

_ae current state of the art of predicting and minimizi%ng lift-induced drag at supersonic speeds as practiced at the Langley Research Center is reviewed.Numerical methods of implementing the linearized theory for use on high-speed electronic computers are outlined, and applications of the methods to wings, wing-body combinations, and complete configurations are studied.It is concluded that the techniques are generally applicable in the supersonic speed range at least up to a Mach number of 3 for configurations employing slender bodies and thin, moderately cambered wings, as represented by current supersonic-transport designs.
