Rolls-Royce reports new success in two-shaft engine research programme

Rolls-Royce reported the successful running of the latest core engine build in its E3E (efficiency, environment, economy) two-shaft research programme. E3E is developing leading-edge technologies which increase engine temperature, pressure ratio and component efficiencies, together with a 25% plus increase in thrust to weight ratios. These technologies are designed to reduce fuel burn and CO2 emissions by 15%, compared to similar engines currently in service. E3E lean-burn will also reduce NOx emissions as part of the company
