The computer program calculates the supersonic flow over a cone in air or water. The main objective is to calculate the cone semi-vertex angle given prescribed initial conditions. The program is written in structured FORTRAN and implements Busemanns graphical integration technique. Supersonic flow over a cone in water is useful as a good first approximation to the motion of the metal jet 0from an explosive shaped-charge fired underwater. A typical result for supersonic flow over a cone in water is as follows given an upstream temperature, 323.16 upstream pressure, 1 bar shock angle, 20.0 deg, and pressure behind the shock front, 5 kilobars, the cone semi-vertex angel is calcuated to be 7.23 deg. Generally, pressures involved in water flow are much larger than for air flow, and the cone semi-vertex angles for water flow are smaller than for air flow.
