The computer program calculates the supersonic flew over a core 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 Busemann's graphical integration technique. Supersonic flow over a cone in water is useful as a good first approximation to the motion of the metal jet from 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 Kelvin; upstream pressure, 1 bar; shock angle, 20.0 degrees; and pressure behind the shock front, 5 kilobars, the cone semi-vertex angle is calculated to be 7.23 degrees. 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 flew.
