Summary:

The accuracy and range of applicability of the linearized theory, second-order theory, tangent-cone method, conical-shock-expansion theory, and Newtonian theory for predicting pressure distributions on pointed bodies of revolution with zero angle of attack are investigated. Various body shapes are included in the investigation and a wide range of supersonic Mach numbers and fineness ratios is included. It is found that, for most combinations of Mach number and fineness ratio, one of the approximate methods will give pressure drag within 10 percent.
