Which turbine stages on an F100-PW-220 engine drive the front compressor?
Third and fourth
What is one advantage of a modular engine?
Entire engines are not withheld from service
One advantage of the modular engine concept is that it eliminates the need to
return whole engines to depot for overhaul

Gearbox
When discussing a jet engine and the location of its parts, you must always do so as if you were standing at the
rear of engine
External flanges on the F100 engine are referred to by
letter designations
On an F100-PW-220 engine, the leading edge vanes are hollow
so that anti-icing air can flow through them
On an F100-PW-220 engine, the total temperature (Tt2) sensor sends electronic signals to the
digital electronic engine control (DEEC)
The F100-PW-220 core module proximate splitter, which divides airflow from the front compressor into fan airflow and primary airflow, is contained in the
compressor intermediate case
On an F100-PW-220 engine, which stages of compressor stator vanes are variable?
Fourth and Fifth
On an F100-PW-220 engine, which stage of compression provides anti-icing air for the engine inlet
Thirteenth
On an F100-PW-220 engine, which devices attach the combustion chamber assembly to the diffuser case
Eight mounting bolts
On an F100-PW-220 engine, the front compressor drive turbine shaft is connected to the front compressor rotor by
the turbine shaft nut coupling
On an F100-PW-220 engine, the augmentor spray rings are pressure sensitive and can adjust their fuel nozzle openings in response to
fuel pressure
Which component on an F100-PW-220 engine sends a signal to drive the primary actuator flexible shaft?
Convergent exhaust nozzle control (CENC)
On an F100-PW-220 engine, the gearbox modules is driven by the rear compressor through
a gearbox drive shaft
How many stages are in the inlet fan module of the F119-PW-100 engine?

Where is the total temperature sensor (Tt2) located on a F119-PW-100 engine
inside the fan inlet guide vane case at the 5:30 o’clock position
Where is the N1 sensor mounted on the F119-PW-100 engine
intermediated case
How many stages are in the high pressure compressor (HPC) of a F119-PW-100 engine?
6
On an F119-PW-100 engine, what function does the diffuser case serve other than housing the combustor?
Reduces the velocity of compressor discharge air
How many gas generator/core fuel nozzles are mounted on the diffuser case of the F119-PW-100 engine?
24
What drives the inlet fan module (IFM) in the F119-PW-100 engine
