Open rotor technology may promise the step-change economic and environmental benefits that the industry is clamouring for, but one company believes it has a simpler, lower-risk answer that will be ...

Airbus and Boeing may have to hold off on a fundamental propulsion decision for the next-generation of narrowbodies until as late as 2013 to allow open-rotor technology to mature sufficiently. Opting ...

OPEN ROTOR: HOW DOES IT WORK? An open rotor engine is essentially a turboprop with two rows of blades, or propellers, which can operate efficiently at higher speeds than a conventional turboprop. The ...

Fuel has declined from its price peak of 2008 and, while renewed research into open-rotor engines continues, easing economic pressures along with tenacious technical challenges could combine to delay ...

Development go-ahead for 2030 entry into service will factor in noise, airframe integration. A mockup of an open-rotor engine has been tested in an Onera wind tunnel since 2010; a full demonstrator is ...
