PW4000 Growth

With a thrust in the range between 84,000 and 98,000 lb. the PW4000 Growth counts among the world's most powerful engines. It equips the Boeing 777-200/-300 and was the first engine with full 180-minute extended-range twin-engine operations (ETOPS) authority. The engine first flew in November 1993 and went into revenue service in 1995.

Meanwhile, there are two versions of the PW4000 Growth engine: the PW4084 and the PW4090. For both versions, MTU developed the seven-stage low-pressure compressor, for which it also manufactures a major part of the components.
