Zen, S T

A rotary engine is described comprising: means for compressing fresh air; an external pressure vessel; an internal pressure vessel inside the external pressure vessel, the internal pressure vessel having walls enclosing a combustion chamber therein; a fuel nozzle in the walls opening into the combustion chamber; means for pumping fuel into the fuel nozzle; means for guiding compressed air compressed by the compressing means into the internal pressure vessel; means for spraying water into the compressed air guided by the guiding means whereby the compressed air guided into the internal pressure vessel carries the water therewith into the internal pressure vessel. The guiding means includes means directing at least a portion of the compressed air and water carried therewith along the wall so as to cool the wall and be converted to compressed steam by heat in the wall and for directing the at least part of the compressed air and steam into the fuel nozzle so as to mix with the fuel pumped into the fuel nozzle to form a compressed air and steam/fuel mixture and be carried therein into the combustion chamber; and an igniter in the combustion chamber for igniting the fuel in the mixture to produce a high temperature, high pressure gas.
