Abstract

A jet-propelled rotary engine comprises a housing, a rotor journalled to the housing for rotation of the rotor about an axis, and at least one jet assembly secured to the rotor and adapted for combustion of a pressurized oxygen-fuel mixture. The jet assembly includes a hollow body having a closed leading end and an open trailing end downstream of the leading end. The hollow body defines a chamber having a combustion region where the pressurized oxygen-fuel mixture reacts during combustion to form combustion reaction products, a throat region downstream of the combustion region, a converging region extending from the combustion region to the throat region, and a diverging region extending from the throat region to the trailing end. The combustion reaction products form at least a part of thrust matter passing through the hollow body and discharged therefrom. The trailing end defines a discharge port for high speed discharge of a jet stream of the thrust matter from the discharge port generally along a line tangent to the rotor periphery for turning the rotor. Water is delivered into the chamber of the jet assembly and is vaporized prior to exiting the throat region of the chamber.
