SOME COMMENTS ON THE FORM OF THE DRAG COEFFICIENT AT SUPERSONIC VELOCITY

Abstract

A form of representation of the drag curve at supersonic velocity is suggested. Only two unknown constants are required for each shell, hence firings at two velocities fix the function. For the case of a conical head and square base, the problem can be reduced to one constant. Good experimental confirmation is found.
