Power Plants Flashcards
Engine
F414-GE-400 low bypass, axial flow, dual-spool turbofan engine of modular construction with afterburner
3 modes of APU
GMM, ECS, MES
IFR
Take fuel while in-flight, forward fuselage
Aircraft fuel storage
Four in internal fuselage tanks, two wing, up to five external
Foam-lined wing tanks
Self-seal holes or damage, decreasing fire and explosion hazards
APU
AMAD
Secondary Power Compressed Air
- gas turbine engine supplying air for ECS operation and MES and GMM through AMADs
- Two gearboxes, mechanically connected to engine by PTS. Pneumatically connected to APU through ATS. AMAD transmits power to engine
- Provides pneumatic power for operating air turbine starter or ECS, provided by APU or engine bleed air
Ignitions
Automatic, intermittent duty, AC powered, capacitor discharge system. Remains energized until rpm is 54% or greater
Lubrication
Dry sump
Main fuel
governs correct main fuel flow IDLE-MIL
Afterburner fuel
Governs correct AB fuel flow from AB start to MAX
VEN
Changes pressure output to provide thrust
Variable Geometry
Fan variable geometry and Compressor Variable Geometry
Anti-Icing
Anti-ice flow to engine front frame center body and inlet device
FADEC
Receives aircraft and engine sensor information and determines appropriate engine scheduling to operate the engine
Throttle
Fly-by-wires system (no mechanical connections) commands and signals sent to and received from FADEC
