What does the APU do?
supply air for ECS, MES and GMM through the AMAD
AMAD what it is and what it does
Airframe Mounted Accessory Drive; connected to the APU through ATS (Air Turbine Starter) Transmits power to the engine for start ups.
Discuss VEN
Variable Exhaust Nozzle; opens and closes allowing more or less air to come through.
How many fuel cells in the F/A-18 A-D or E-F
4 fuel cells.
What is FADEC and its purpose
Full Authority Digital Engine Control ; receives sensor information and determines engine scheduling to operate in all areas of the flight. The brain of the engine.
System interface between APU, AMAD and Engines
AMAD is connected to APU then AMAD transits power to the engines for starts.
Fuel Pressurization and Vent
maintains pressure on the fuel. Let out fuel Vapors.
Hot Fuel Recirculation
fuel separates at the heat exchanger, filters fuel. Ex Oil to fuel or fuel to Oil.
Purpose of Air Refueling Store
provides in-flight refueling, has tanker capabilities. When installed the A/C becomes a tanker/capable of refueling other aircraft.
