To balance the conflicting goals of high power, light weight, fuel economy and low noise - not to mention a profitable bottom line for the engine makers - engineers are deploying a range of new computerised design technologies to run exotic materials and novel designs into the next generation of powerplants. Among the contenders for driving the airliners of the 2020s and 2030s are open-rotor concepts, a promising configuration abandoned in the 1980s for its unacceptably high noise output
