Pratt & Whitney PW6000

The PW6000 is a turbofan engine developed by Pratt & Whitney to power the Airbus A318. It entered service in 2007 with a design thrust range of 18,000 to 24,000 lbf (82 to 109 kN). The Pratt & Whitney PW6000 is a high-bypass turbofan which was designed to significantly reduce maintenance cost and achieve weight and fuel consumption savings.

Originally the new PW6000 had a 5-stage high-pressure compressor, but tests revealed that this initial high pressure compressor did not meet promised fuel burn performance. To address the problem, Pratt & Whitney re-certified an updated design using a 6-stage high pressure compressor designed by MTU Aero Engines in order to achieve promised performance.
