Lesson 1Turboprop engine types: turboprop core, free-turbine vs fixed-shaft, common modelsThis covers the turboprop core setup, compressor, combustor, and turbine parts. It compares free-turbine and fixed-shaft types, talking about starting, control, and breakdown ways. It looks at usual King Air and ATR engine types and how they affect maintenance.
