The design of an aircraft engine typically follows a structured sequence:

: Uses multiple stages of rotating blades and fixed stators to increase air pressure.

: Directs high-velocity gas out of the engine to produce thrust.

: Extracts energy from hot gases to drive the compressor and other accessories. Turbine blades often feature film cooling (tiny holes) to survive extreme temperatures.

Modern gas turbine engines are complex systems consisting of several critical sub-assemblies:

: Where fuel is mixed with high-pressure air and ignited to release energy.
