Pratt & Whitney has completed flight testing of its improved PW2000 engine mounted aboard a Condor 757 (refer p9 Mar '94 AA). The improvement package enhances turbine durability, increases engine time on wing up to 20,000 hours and can potentially cut maintenance costs by as much as 22% by reducing the combuster exit temperature. Advanced materials and thermal barrier coatings and cooling in the new package significantly increase the PW2000's durability. (P&W)
