General Electric GEnx-2B
The General Electric GEnx-2B is the high-bypass turbofan line developed for the Boeing 747-8. It uses two independent rotors: a two-stage high-pressure turbine drives the ten-stage core compressor, while a six-stage low-pressure turbine drives the fan and three-stage booster compressor. Full-authority digital engine control manages operation. The -2B line includes separately certified models such as GEnx-2B67, -2B67B and -2B67/P, with model-specific ratings and limitations.
