FIELD: heat engineering; jet engines for aerospace aircraft. SUBSTANCE: incoming air flow is decelated in air intake and gets compressed. water fed to surface of its central body forms film. Air flow heated during compression interacts with water film and is cooled due to evaporation of water. Cooled and humidified air enters the combustion chamber where fuel is burnt. Combustion products escape through nozzle. Efficiency of engine in placing the aerospace vehicle in near-earth orbit is enhanced due to control of water flow rate. EFFECT: enhanced efficiency. 1 dwg
