What type of engine is used on F/A-18E/F?
|
F414-GE-400
|
|
|
What type of engines are used on F/A-18 A-D's?
|
F404-GE-400 or F404-GE-402
|
|
|
What kind of engines are used on F/A-18's?
|
Low bypass, axial flow, dual-spool turbofan engine of Modular construction with afterburner.
|
|
|
What is the Ignition system?
|
It is automatic, intermittent duty, AC powered, capacitor discharge system.
|
|
|
What is the Ignition System circuitry?
|
It is self-contained on the engine, requiring no aircraft electrical power for operation.
|
|
|
When is the ignition system remain energized?
|
Until N2 rpm is 54% or greater or the throttle is restarded below idle.
|
|
|
What is the Ignition System made up of?
|
- Alternator
- ECA - Engine Fuel Control - Ignition Exciter - Main Igniter - AB igniter - AB flame sensor - Two Fan Speed Transmitters - Thermocouple harnesses |
|
|
How is Lubrication accomplished?
|
Through a self-contained recirculation, dry sump requiring no external connections or inputs.
|
|
|
What does the Lubrication system provide?
|
Lubrication/Cooliong to the required bearings and gears.
|
|
|
What is the VEN?
|
It is a cam and link-positioned hinged-flap, convergent-divergent nozzle, mounted to the aft end of the Afterburner case.
|
|
|
How is the VEN operated?
|
It's hydraulically (fuel) operated, electrically controlled series of actuators, synchronizing shafts, links, flaps, seals, providing a controlled throat area (A8) for the exhause gasses from the turbine and AB.
|
|
|
Why is the VEN controlled?
|
To provide required thrust and fuel efficiencies while maintaining exhaust gas temperature (T5).
|
|
|
What does the Variable Geometry consists of?
|
The Fan Variable Geometry (FVG) and Compressor Variable Geometry (CVG).
|
|
|
What does the FVG provide?
|
Best efficiency of the fan while preserving fan stall margin.
|
|
|
What does the CVG provide?
|
Best efficiency of the compressor while preserving compressor stall margin.
|
|
|
What does the Anti-Icing system provide?
|
Anti-ice air flow to the engine front frame, inlet center body, and inlet device. It prevents the build-up of ice on air inlet hardware.
|
|
|
How is the Anti-Icing system actived?
|
It is manually activated by the pilot. Signaling the ECA to activate the anti-icing valves.
|
|
|
What is the purpose of the ECA?
|
Receives aircraft and engine sensor information and determines the appropriate engine scheduling to operate the engine in all areas of the flight envelope/
