PW2000

Over the years, the Pratt&Whitney PW2000 engine was modified to improve performance and efficiency, and reduce CO₂ and noise emissions (PW2000 Reduced Temperature Configuration - PW2043). The launch of the programme started up in 1979, and entry into service in 1984, while the last Boeing B757 that used the engine was produced in April 2005.

Avio, partner of Pratt&Whitney, was responsible for the design and development of the accessory drive train and of the oil tank and is now responsible for the production of spare parts.

The PW2000 is a turbofan twin-shaft engine with high-dilution ratio. It is equipped with a Full Authority Digital Electronic Control (FADEC) system. It has a twin-shaft configuration featuring:

• high-pressure compressor with twelve axial stages 
• two-stage high-pressure turbine
• five-stage high-pressure turbine
