STEAM-GAS ENGINE Russian patent published in 1996 - IPC

FIELD: power engineering. SUBSTANCE: engine has ramjet steam generator, facility for mixing combustion products, guide nozzle set, active turbine with exhaust utilizer connected with the turbine shaft through reduction gear, consumer (e. g. , a propeller), water pump whose outlet is connected with the steam generator, and means for supplying fuel and oxidizer. The steam generator is made up as a fire pipe which is diverging in the direction of the flow of combustion products and provided with a pipe which tightly abuts against its outer surface. The pipe is made up as a spiral whose outlet is connected with the steam collector. The outlet of the steam collector is coincident with the active nozzle of the mixing chamber. The guide set is mounted at the outlet of the Laval nozzle inlet of which is coaxial to the active nozzle inside the mixing chamber. The blades of the peripheral- admission turbine is rigidly secured to the heat conducting disk. The means for supplying oxidizer is made up as a rotary compressor the blades of which are secured to the back side of the disk. EFFECT: enhanced efficiency. 4 cl, 3 dwg
