Rolls-Royce Trent 700 Benefits From Technology Development Flow-Back
The initial Rolls-Royce Trent 700 enhanced-performance (EP) retrofit kit includes optimized turbine-case cooling and intermediate- and high-pressure compressor blades with elliptical leading edges.

Rolls-Royce (R-R) is developing continuous improvements for mature Trent engines, with new technology flowing from later models into established variants, according to program director John Hogarth. Since the original Trent–the Series700–entered service on a Cathay Pacific Airbus A330 in 1985, successive variants have been introduced to constitute a “tailored family” enjoying common architecture, but with each model dedicated to specific airframes.
