The Commercial Aircraft Corporation of China (Comac) said its ARJ21 flight-test program has passed the 500-hour mark. Four General Electric CF34-10A-powered ARJ21-700 aircraft are participating in the test program. GE has provided engine spares to Comac, in addition to carrying out its own ground testing involving three engines totaling 750 hours of testing.

GE Aviation received an award from the FAA as part of the Continuous Lower Energy, Emissions and Noise (Cleen) program–a joint government-industry initiative to accelerate the development and maturation of aircraft and engine technologies that cut noise, emissions and fuel burn. Under the program, GE and the FAA will share an investment of up to $66 million over a five-year period.
The FAA has awarded Pratt & Whitney a one-year contract under its Continuous Lower Energy, Emissions and Noise (Cleen) program to develop engine technology aimed at reducing specific fuel consumption, noise and engine emissions. This funding will support Pratt & Whitney 's ongoing development of its PurePower geared-turbofan engine.
CFM International has completed the second phase of testing of the Leap-X core demonstrator known as eCore 1, meaning 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.
The June 16 first flight of the fifth Boeing 787 Dreamliner (ZA005) also marked the first time a pair of GE Aircraft Engines' GEnx-1B turbofans powered an airplane to altitude on their own. Captains Mike Bryan and Mike Carriker flew the airplane for three hours and 48 minutes, and reported no anomalies.
The Powerjet SaM146 received its EASA certification yesterday, June 23, some six years after Snecma of France and Russia's NPO Saturn founded the joint venture to build the engine and more than seven years after Sukhoi Civil Aircraft chose the engine to power the Superjet 100.
Composites and other new and expensive materials play key roles in the engines that will power new single-aisle airliners, such as the Comac C919, Bombardier C Series and, possibly, Airbus A320 and Boeing 737 upgrades. Pratt & Whitney and CFM aim to make their future engines more efficient with material changes-some low profile, others better known-that all contribute to double-digit improvements in fuel consumption.
Boeing's decision to re-engine the existing 737 will depend not only on the actions of arch-rival Airbus, but whether or not the Chicago-based airframe maker concludes that it could bring to market a good enough replacement airplane by 2020, Boeing CEO Jim McNerney told analysts and investors at last week’s Sanford C. Bernstein Strategic Decisions Conference in New York.
It seems Boeing hasn’t convinced everyone of the value of its standard engine interface feature on the 787 Dreamliner, which the company says allows quick and cost-effective changeability between the Rolls-Royce Trent 1000s and GE GEnx-1B turbofans chosen to power the airplane.
