by means of an electrical transmitter. The transmitter is connected
to a tap on the valve manifold where all the fuel supply lines join
to deliver fuel to the engine through the fuel control inlet hose.
Electricity is supplied to the transmitter by the 28volt ac system.
The three types of ignition systems used on turbine engines
are induction, capacitor discharge, and glow plug. The most common
ignition system used on Army aircraft is the capacitor discharge.
The induction and capacitor systems use a spark producing plug to
ignite the fuel air mixture.
Because of the high operating temperatures of turbine engines,
an internal cooling system is used. Cooling air forms a blanket of
pressure and temperature gages for monitoring engine performance.
