Concise accurate graphs of cone flow properties at zero yaw in air as a perfect gas are presented in correlation form. From these graphs the pressure, density, temperature, shock angle, and Mach number may be obtained both at the cone surface and immediately behind the shock, for free-stream Mach numbers from that for shock detachment to that approaching infinity and for cone semi -apex angles up to 50°. In addition, the initial slope of the normal-force curve is given for the same range of conditions.

A computer program is presented for calculating the various components comprising the total drag coefficient for slightly blunted slender cones. The program is applicable for either the case of a completely laminar boundary layer or where transition occurs on the cone. Weak viscous interaction effects are taken into account. Local flow properties which exist at the outer edge of the boundary layer along the cone are also computed. (Author).
