The power behind the flown

To balance the conflicting aeroengine 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 turn exotic materials and novel designs into the next generation of powerplants. Among the contenders for driving the airliners of the 2020s or 2030s are open-rotor concepts, a promising configuration abandoned in the 1980s for its unacceptably high noise output. Quiet revolution : open-rotor engines promise a new era of fuel efficiency but their inherently high noise has ruled them out--until now / Stephen Trimble -- Snecma eyes leap to open rotors for next-generation narrowbodies / Andrew Doyle -- Scaling the Alps : Rolls-Royce's advanced lightweight low-pressure system is its project to develop a first partly-composite blade / Andrew Doyle -- 'Low-level' work on open rotor designs / Andrew Doyle -- Geared up to grow : MTU's bolstered role in design, producion and assembly of the PW1000G geared turbofan should help to secure the German firm's position in the market for a generation / Murdo Morrison.
