General Electric CF34-3B1
General Electric CF34-3B1 exact turbofan variant in the CF34-1/3 series. EASA rates normal five-minute takeoff thrust at 38.83 kN (8,729 lbf), APR takeoff thrust at 41.01 kN (9,220 lbf), and maximum continuous thrust at 40.66 kN (9,140 lbf); GE specifies a 6.2:1 bypass ratio and 14:1 overall pressure ratio. GE records November 1992 entry into service, while the existing CRJ 200 family relationship remains separate from this propulsion identity.
