The ramjet is shown schematically in this figure. The ramjet operates on a thermodynamic cycle which is basically the same as that of the turbojet. Air is admitted at the forward end, compressed by diffusion, heated in the reactor and expanded through the jet nozzle to provide forward thrust. Since sufficient compression is provided by inlet diffusion at high flight speeds, the requirement for rotating turbo-machinery is eliminated.
