Engines
- Four strokes: intake, compression, power, exhaust; valve overlap near TDC
- HP = PLANK / 33,000; differential compression test at 80 psi
- Turbines: Brayton cycle; hot start = EGT over limit; disks life-limited in cycles
Electrical, ignition and starting
- CSD/IDG holds 400 Hz; commutator rectifies DC generator output
- Impulse coupling = retarded, hot starting spark; open P-lead = hot magneto
- Turbine exciters store lethal energy — wait before disconnecting
Fuel, oil, induction and air
- Venturi drives float carburetor; continuous-flow injection nozzles in intake ports
- Dry sump = separate tank; chip detectors and oil analysis track wear
- Carb ice up to ~70°F; wastegate controls boost; bleed valves prevent stall
Exhaust, fire and propellers
- No pencil marks on exhaust parts; cascade reversers turn fan air forward
- Class B = flammable liquids; continuous-loop resistance drops with heat
- Overspeed → governor increases pitch; feather to cut drag; stations from hub center
