Rolls-Royce has announced that it has successfully run the latest core engine build in its E3E (efficiency, environment, economy) two-shaft research program.
“Our E3E technology, which is at the heart of our future two shaft engine product strategy, continues to make great progress,” said RR’s president of civil aerospace Mark King.
E3E is aimed at developing new jet engine technologies which increase engine temperature, pressure ratio and component efficiencies, together with a 25 per cent-plus increase in thrust to weight ratios. The company claims that the improvements being tested could reduce fuel burn and CO2 emissions by 15 per cent.
RR is aiming to use two-shaft technology to develop a new narrowbody engine which could compete against Pratt & Whitney’s PW1000G geared turbofan and CFM International’s LEAP-X engines to power the replacements to the Boeing 737 and Airbus A320.
