Engine with rotary combustion chamber (20) and ram jet compressor (7). An engine which is particularly suitable for propulsion of a water craft using direct thrust has a rotary body (1, 4) which includes a ram jet compression section (12) formed with a number of helical passages which decrease in area towards a rotary combustion chamber (20). Vectored exhaust ports (26) produce rotary thrust for operating the compressor (7), and superheated water used for cooling the engine is injected into the combustion chamber (20) or the exhaust flow to increase the thrust by rapid expansion.
