General Electric CF34-8C

General Electric CF34-8C is a turbofan model grouping covering the certified -8C5B1 and -8C5 variants. GE's propulsion datasheet lists 13,790 lbf maximum takeoff thrust for -8C5B1 and 14,500 lbf for -8C5, with a 5:1 bypass ratio; overall pressure ratio is 28:1 for -8C5B1 and 28.5:1 for -8C5. The family is applied to CRJ700/900/1000 and Challenger 870/890; exact dash variants and vehicle-family relationships remain separately modeled.

    Note
    GE's CF34-8C propulsion datasheet enumerates CRJ700/900/1000 and Challenger 870/890 applications and distinguishes -8C5B1 at 13,790 lbf maximum takeoff thrust, 5:1 bypass, and 28:1 overall pressure ratio from -8C5 at 14,500 lbf, 5:1 bypass, and 28.5:1 overall pressure ratio; the ratings are retained as dash-variant context rather than generalized to the model grouping.
