Abstract : Application of the pressure-velocity diagram to subsonic combustion processes is already established. It is shown here that this form of representation can be extended to combustion processes in the supersonic range subject to rectilinear and oblique compression shocks. Likewise detonation processes, usually analysable only by means of Rankine-Hugoniot curves, can be clearly plotted in pressure-velocity diagrams. Assuming a supersonic combusion in a ram-jet engine comprising a cylindrical combustion chamber and exhaust nozzle, it is possible to conduct comparative studies of propulsive efficiency, thrust values and pressure losses due to such combustion.
