Engine Fuel System

Managed by the FADEC. Fuel enters the engine through the engine fuel pump inlet, and from the fuel boost element fuel either continues through the heat exchanger to the engine, or is returned as motive flow for the fuel tank ejector pumps.

Fuel flow: fuel boost element → main element → fuel filter → FMU → fuel injectors

Fuel control system

• FADEC
• FMU
• PMA
• engine sensors
• variable geometry (VG) actuators
• transient bleed valve (TBV)

Fuel distribution system

• fuel pump
• fuel filter
• fuel manifold
• 20 fuel injectors (mounted in combustor frame)
