FIELD: aircraft engineering.
SUBSTANCE: invention is designed for rotating propellers of different application. Proposed centrifugal ramjet engine contains combustion chamber 4 with reaction nozzle 5 to which compressed air is fed through inlet hole 3 and inlet air duct 2 with preliminary compression in compression chamber 6 owing to velocity head at movement of engine over circumference together with propeller blade 1 secured on engine shaft to end of which it is connected. Compressed air from compression chamber moves along radial air duct 7 into combustion chamber with acceleration under action of centrifugal force appearing at rotation of propeller. Air flow getting in specified order provides dynamic pressure onto wall of combustion chamber, thus ensuring additional compression of air, and fuel is combusted in said area of increased compression of air. Gaseous combustion products move at acceleration from combustion chamber through reaction nozzle, thus creating reactive thrust. Combined use of ramjet and centrifugal capabilities provides considerable compression of air which increases efficiency of engine in operation.
EFFECT: provision of effective engine of simple design and low weight.
