Trent 800

A good example of this technology feedback arises from Trent 1000 “elliptical leading-edge” (ELE) high- and intermediate-pressure compressor (HPC and IPC) blades, which reduce fuel burn and are now available for Trent 800 EP and Trent 500EP+ applications. Hogarth said the blade’s “sophisticated aerodynamics,” which reduces airflow separation behind the leading edge, provides a 0.5- to 0.7-percent benefit to fuel consumption worth “up to $200,000 per aircraft per year.” First customer orders have been agreed, perhaps for announcement here at Le Bourget.
