Opening through which the exhaust gases are evacuated; the duct is usually cone-shaped in order to narrow the gas flow, thus increasing thrust.
power turbine
Turbine that is driven by the gases expelled by the combustion chamber; it drives the axial compressor and the fan. It is independent of the compressor turbine.
ignition box
Device that produces the electric pulses supplying the system that sets off combustion.
compressor turbine
Turbine that is activated by the gas produced in the combustion chamber; it drives the centrifugal compressor and the accessories.
fuel control
Device measuring the amount of fuel injected into the combustion chamber.
accessory gearbox
Mechanism that drives various accessories such as the alternator and the hydraulic, fuel and oil pumps.
mounting point
Part where the engine is mounted on the aircraft.
nose cone
Part located on the tip of the fan axle that creates an aerodynamic airflow into the fan blades.
exhaust guide vanes
Protruding parts directing the exhaust gases straight out.
bypass duct
Channel that conducts some of the air sucked in by the fan, which contributes to the engine’s thrust.
annular combustion chamber
Enclosure consisting of two concentric hydraulic cylinders that surrounds the turbine-compressor shaft and where combustion occurs.
turbine-compressor shaft
Axle transmitting the turbine’s rotational movement to the compressors.
pipe diffuser
Conduit with several exit orifices that connects the centrifugal compressor to the combustion chamber; its purpose is to direct the flow and slow down the airflow to increase its pressure.
centrifugal compressor
Engine components that use centrifugal force to compress air and expel it at very high speed to the combustion chamber by the pipe diffuser.
inner stators
Set of fixed blades that corrects the airflow that is deflected as it passes through the blades of the axial compressor.
outer stators
Set of fixed blades that corrects the airflow that is deflected as it passes through the fan.
axial compressor
Engine component in which air is highly compressed by a set of small fan blades to increase the engine’s output and reduce fuel consumption.
exhaust
Phase during which the air expands and produces a thrust that activates the turbines and propels the turbofan engine.
combustion
Phase during which the compressed air enters the combustion chamber, where it is mixed with fuel and ignited.
compression
Phase during which some of the air flowing through the engine is compressed before it enters the combustion chamber.
