TECH GENERAL — CHAPTER 8
Turbine Engines
DGCA Syllabus — What to Know
Principles of operation, types (turboprop, turbojet, turbofan). Construction: air inlet, compressor (stall/surge), diffuser, combustion chamber (types, fuel injectors, thermal load), turbine (thermal/mechanical stress), jet pipe (types, noise silencing). Pressure/temperature/airflow, reverse thrust, bleed air effects, auxiliary gearbox. Engine systems: ignition, starter (malfunctions), fuel, lubrication. Thrust formula, flat rating, APU, RAT.
