The experimental wave drags of bodies and wing-body combinations over a wide range of Mach numbers are compared with the computed drags utilizing a 24-term Fourier series application of the supersonic area rule and with the results of equivalent-body tests.nThe results indicate that the equivalent-body technique provides a good method for predicting the wave drag of certain wing-body combina¬tions at and below a Mach number of 1. At Mach numbers greater than;1, the equivalent-body wave drags can be misleading. The wave drags com¬puted using the supersonic area rule are shown to be in best agreement with the experimental results for configurations employing the thinnest wings. The wave drags for the bodies of revolution presented in this report are predicted to a greater degree of accuracy by using the frontal projections of oblique areas than by using- normal areas. A rapid method of computing wing area distributions and area-distribution slopes is given in an appendix.
