: Extracts energy from hot gases to drive the compressor and other accessories. Turbine blades often feature film cooling (tiny holes) to survive extreme temperatures.
: Where fuel is mixed with high-pressure air and ignited to release energy. Aircraft Engine Design
: Uses multiple stages of rotating blades and fixed stators to increase air pressure. : Extracts energy from hot gases to drive
: Directs high-velocity gas out of the engine to produce thrust. Aircraft Engine Design
Modern gas turbine engines are complex systems consisting of several critical sub-assemblies:
