(Optional) Explain turboprop engine operation.

Explanation should include the following:

• The turboprop engine consists of four sections.
  • The compressor section passes inlet air at a high speed.
  • The combustion chamber contains the fuel inlet and igniter for combustion.
  • The expanding air drives a turbine, which is connected by a shaft to the compressor, sustaining engine operation.
  • The accelerated exhaust gases from the engine provide thrust.
• This is a basic application of compressing air, igniting the fuel-air mixture, producing power to self-sustain the engine operation, and exhaust for propulsion.
