What 3 elements are necessary for engine operation? - ANSWER Air, fuel,
heat
What are the 3 engine sections? - ANSWER Accessory compartment, gas
generation section, power turbine section
What is the initial function of the accessory compartment? - ANSWER Starter
turns compressor, Provides initial airflow
What are the components of the Ignition System? - ANSWER Exciter box,
Igniter cables, Igniters
Describe the operation of the Ignition System components - ANSWER Exciter
converts low voltage input to high voltage output, High voltage is routed to the
igniters and sparked to the fuel mixture
What is the continuing function of the Accessory Compartment? - ANSWER
Compressor shaft turns the accessory gearbox which contains a generator, Oil
Pump, Hydraulic Pump, Fuel Pumps
What is the function of the Gas Generation Section? - ANSWER Air is
compressed, Compressed, air mixed with fuel, Mixture is ignited, Expanding
gases drive compressor turbine (Suck, Squeeze, Bang, Blow)
How is the Gas Generator controlled? - ANSWER PCL, Mechanically and
electrically connected to FMU
What are the functions of the PMU? - ANSWER Processes power requests,
Maintains operating limits, Provides near linear power response
What is the function of the Power Turbine Section? - ANSWER Expanding
gases drive compressor and power turbines, Power turbines drive propeller
through reduction gearbox, Exhaust is released into the atmosphere
