CFM International CFM56-7B26/B1
CFM International CFM56-7B26/B1 is a dual-rotor, axial-flow, high-bypass turbofan in the CFM56-7B SAC model group. EASA E.004 Issue 07 describes a single-stage fan, three-stage low-pressure compressor, nine-stage high-pressure compressor, annular combustion chamber, single-stage high-pressure turbine, four-stage low-pressure turbine, and dual-channel FADEC. It rates CFM56-7B26/B1 at 116.99 kN takeoff thrust and 115.21 kN maximum continuous thrust. The canonical CFM56 family link, GE/Safran developers, CFM International manufacturer, exact /B1 suffix, and existing Boeing 737-family installation are preserved.
