TYPE
The GEnx-1B engine is a dual rotor, axial flow, high bypass ratio turbofan. The 10-stage high pressure compressor
is driven clockwise (Aft Looking Forward) by a 2-stage high pressure turbine. The single stage fan and 4-stage
low pressure compressor are driven counterclockwise (Aft Looking Forward) by a 7-stage low pressure turbine.
The engine control system includes a Full Authority Digital Engine Control (FADEC), which has an aircraft
connection for digital communication. An engine monitoring unit (EMU) provides vibration level signals to the
aircraft.
The GEnx-2B engine is a dual rotor, axial flow, high bypass ratio turbofan. The 10-stage high pressure compressor
is driven clockwise (Aft Looking Forward) by a 2-stage high pressure turbine. The single stage fan and 3-stage
low pressure compressor are driven counterclockwise (Aft Looking Forward) by a 6-stage low pressure turbine.
The engine control system includes a Full Authority Digital Engine Control (FADEC), which has an aircraft
connection for digital communication. An engine monitoring unit (EMU) provides vibration level signals to the
