Idealized Wings and Wing-bodies at a Mach Number of 3

Report presenting the theoretical possibilities for obtaining high lift-drag ratios at M = 3 and to describe some experiments designed to exploit the theory. Relatively high lift-drag ratios calculated were partly realized at low wind-tunnel Reynolds numbers. The rate of increase in maximum lift-drag ratio with increased Reynolds number was greater than expected, which indicated a need for more experiments at conditions closer to actual flight.
