The behaviour of the wave drag coefficient of a certain optimum body in off–design conditions.

In this report the drag-coefficient of an optimum body with a conical nose has been determined. The body was designed for a Mach number of the undisturbed stream equal to 3. It is found that the curve for the drag coefficient shows a definite kink at the design Mach number. The conclusion is reached that a more general approach for designing...
