GENERAL
The Challenger 605 is equipped with two General Electric CF34-3B high-bypass ratio turbofan
engines.
The dual-assembly engine consists of a fan rotor (N1) and a compressor rotor (N2). The N1 rotor is
comprised of a single-stage fan connected through a shaft to a four-stage low-pressure turbine. The
N2 rotor is a 14-stage axial flow compressor connected through a shaft to a two-stage high-pressure
turbine. The accessory gearbox is mechanically driven by the N2 compressor.
Normal takeoff thrust rating is 8,729 pounds per engine. During engine-out operation, the automatic
performance reserve (APR) system increases thrust on the operable engine to 9,220 pounds.
FLAT-RATED THRUST
Outside air temperature and pressure altitude are determining factors in achieving takeoff and APR
power. Increases in ambient temperature or pressure altitude adversely affect the engine’s ability to
