RAMJET ENGINE Russian patent published in 2002 - IPC

FIELD: aircraft. SUBSTANCE: ejector ramjet engine for aircraft designed for use in wide range of speeds from zero to hypersonic speeds has air intake with relatively small cross-section connected to mixer placed in passage duct in direction of flow, mixer including atomizer head unit installed in flow zone in mixer from side of air intake to form ejector, and fluid medium supply system coupled with atomizer head unit. Said unit has atomizing ring with several nozzle holes orientated to direct fluid medium flow at outlet in direction of flow with partial displacement relative to longitudinal axis of engine. Diffuser installed behind the mixer has cross-section increasing in direction of flow, combustion chamber has cross-section exceeding cross-section of mixer. Fuel supply system is coupled with combustion chamber. Outlet nozzle installed behind combustion chamber has widening part with cross-section exceeding cross-section of combustion chamber and is furnished with adapter throttle arranged between combustion chamber and outlet nozzle. Central fairing is installed along longitudinal axis of engine in combustion chamber. Central fairing is provided with control device to change cross-section of outlet nozzle. EFFECT: possibility of operation of engine in range of speeds from zero to hypersonic at altitudes up to 46 km. 6 cl, 10 dwg
