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.

Pratt & Whitney’s F135 engine has achieved a first for the Lockheed Martin F-35 program by accelerating the F-35B STOVL version through the sound barrier last month. The test aircraf–BF-2–climbed to 30,000 feet and accelerated to Mach 1.07 at the off-shore test track near NAS Patuxent River in Maryland on June 14. The F-35 has supercruise capability and does not require the use of engine afterburner to achieve supersonic flight.

The FAA has awarded contracts valued at $125 million to several manufacturers to develop and demonstrate technologies that will reduce jet aircraft fuel consumption, emissions and noise. The contracts–awarded to Boeing, General Electric, Honeywell, Pratt & Whitney and Rolls-Royce North America–are part of the agency’s Continuous Lower Energy, Emissions and Noise (Cleen) program.

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 first Boeing 787 Dreamliner powered by General Electric GEnx-1B engines–ZA005–completed its first flight at 6:29 p.m. Pacific time yesterday, following a three-hour-and-48-minute maiden mission over the state of Washington.

GE executives and Boeing employees assembled to welcome captains Mike Bryan and Mike Carriker to Boeing Field in Seattle following completion of the flight.

The Boeing X-51A WaveRider hypersonic vehicle, powered by a Pratt & Whitney Rocketdyne scramjet engine, achieved aviation history this week by making the longest ever combustion ramjet-powered supersonic flight. During its first jaunt, the craft reached 70,000 feet and an approximate speed of Mach 5 on a 200-second flight over the Pacific Ocean on May 26 at 10 a.m. before it was purposely crashed into the water.
