The Pratt&Whitney PW4000-94 engine is destined for twin-engine aircraft such as the A300 and B747. The advanced technologies used like the turbine with “single-crystal” airfoils and the FADEC, have contributed to reliability, and guaranteed optimised fuel consumption.
The current PW4000 engine satisfies and forestalls the present requisites of polluting and noise emissions. To guarantee a further reduction in emissions, especially NOx, the new technology TALON (Technology for Advanced Low NOx) is available for the combustor.
Avio, partner of Pratt&Whitney, is responsible for the production and supply of spare parts for the Accessory Drive Train and Oil Tank.
The PW4000-94 is a twin-shaft turbofan engine with a high-dilution ratio.
It is equipped with a Full Authority Digital Electronic Control (FADEC) system.
It has a twin-shaft configuration featuring:
| Max Power at SL | 52.000 - 62.000 lb |
| Fan diameter | 94 inches |
| Overall pressure ratio | 27.5 - 32.3 |
| Bypass ratio | 4.8 - 5.0 |
| Accessory Drive Train |
