Manufacturers of airliners typically offer customers a choice of engines for their various models. The new Airbus A350 XWB is not one of them, however. It is powered only by the Rolls-Royce Trent turbofan, and one question often asked is, “Will GE offer an engine to power the Airbus A350 XWB?”

China’s homegrown Comac C919 will be the first airliner in the world to fly with a truly integrated propulsion system (IPS) combining engines with nacelles for improved overall efficiency. The IPS concept is being pioneered by Nexcelle, a joint company formed last year by GE Aviation’s Middle River Aircraft Systems and the Safran group’s Aircelle. GE and Safran also jointly own CFM International, supplier of the C919’s Leap X1C engine.
Pratt & Whitney believes open rotors are not the solution to powering future single-aisle aircraft and will offer developed versions of its PW1000G series of geared turbofans for all new and derivative single-aisle aircraft.
Under a plan first revealed two years ago, Rolls-Royce and British Airways have invited fuel suppliers to participate in tests to evaluate alternative aviation fuels in a study to seek practical alternatives to kerosene, the current standard fuel. The two companies have requested samples for possible laboratory and rig trials and, ultimately, tests on a Rolls-Royce RB211-524G engine from a British Airways Boeing 747-400.
Pratt & Whitney Canada has launched an all-new turboprop engine for regional aircraft to replace the 1,800- to 5,000-shp PW100 series. It expects to run the core demonstrator in the second half of next year.
CFM International comes to the Farnborough airshow with the first application for its new Leap-X engine under its belt and ready to offer more advanced versions to Boeing and Airbus for either new or re-engined versions of their respective single-aisle aircraft.
Engine maker Rolls-Royce is preparing the technology needed for new two-shaft and three-shaft turbofan engines in the second half of this decade and an open-rotor design in the early 2020s.
“Our long-term strategy is to invest in technology and protect our options,” said Mark King, Rolls-Royce president of civil aerospace. “Two years ago we decided to make sure we were capable of whatever the manufacturers want.”
Rolls-Royce has received awards valued at $16 million for its participation in the FAA’s Continuous Lower Energy, Emissions & Noise (Cleen) technologies program, the company announced today.
GE Aircraft Engines plans to build 100 GEnx engines this year and double that number next year, as the company accelerates production to meet a demand for 700 units from now through 2013. Now flying engines on the Boeing 747-8 and the 787 Dreamliner, GE–as of June 1–had built 28 GEnx-2Bs for the Boeing 747-8 and some 20 for the GEnx-1Bs for the 787.
CFM International has completed the second phase of testing of the Leap-X core demonstrator known as eCore 1. This means that all three major elements of the first core–the turbine, the combustor and the compressor– have undergone evaluation. The results, according to Leap program director Ron Klapproth, have matched or exceeded all the company’s early projections, leaving the program on schedule for certification in late 2014.
