PW4000

PW4000

PW4000 is a type of turbofan engine manufactured by Pratt & Whitney. It has a high bypass ratio of 5.1:1, making it suitable for use in long-haul aircraft such as the Boeing 747 and 777. The PW4000 series was built in the 1990s and is known for its reliability and efficiency.From: Gas Turbine Handbook Second Edition [2002], Exergo-sustainability behavior of high by-pass turbofan engine of a passenger aircraft during main flight phases [2021], Aircraft Propulsion and Gas Turbine Engines [2019]

The PW4000 engine is classified as high bypass ratio turbofan engine to be installed in long-haul aircraft such as Boeing-747. A large number of PW4000 have been manufactured from 1987 up to day. Their produced thrust ranges change between 231 kN and 271 kN. The PW4000 engines typically incorporate Fan, LPC with four cascades, HPC with 11 cascades, the combustor, HPT with two cascades and LPT with four cascades. Since by pass ratio is five, about one-fifth of air is passed through LPC cascades (Benawra et al. 2015). The remaining air is rejected to Fan exhaust. At take-off phase, the highest fuel flow is observed as 2.65 kg/s, whereas it has different values in the other phases as shown in Table 1.
