What component in the F100 monitoring system provides the operator information concerning how much ( in percentage) the augmentor nozzle is opened or closed?
Augmentor Nozzle positioning indicator
Where is the fuel flow transmitter located in the F-15?
In the engine bay
What component in the F110 monitoring system performs diagnostics and fault isolates to line replaceable units?
Engine Monitoring System Computer
What component or components make up the engine monitoring system on the F119 engine itself?
CEDU and FADEC
What component in the F119 engine monitoring system processes and stores vibration signals, oil debris signals, oil level signals, condition monitoring and fault information data in resident memory?
CEDU
What is the basic function of an augmentor (afterburner) when it is not operating?
Act as the basic engine tailpipe
What is used to open and close flap-type and iris-type variable-exhaust nozzle systems?
Air pressure for both types
The most important advantage of using a C-D nozzle system is the
life expectancies of the engine and augmentor are increased
What component heats augmentor fuel to provide better vaporization and combustion?
Fuel/oil cooler
Which system employs a small combustion chamber to ignite the fuel in the augmentor (afterburner) duct?
Torch igniter
What are the two main types of augmentor (afterburner) ignition systems?`
Torch igniter and pilot burner ring
On the F100 engine augmentor, the divergent and convergent nozzle segments complete a four-bar linkage arrangement that controls the
Aj
The F100 engine augmentor’s primary nozzle actuator is driven by cables from the
CENC
The F100 engine augmentor’s exhaust nozzle is variable to control engine
thrust and fan stall margin
What component in the electronic/mechanical controls is a fuel cooled digital computer that provides signals to the MFC for control of the front compressor speed (N1), rear compressor speed (N2), engine airflow, combustion chamber pressure (Pb4) and FTIT
