A new General Electric turboprop engine, derived from the 7,500-shp GE38-1B turboshaft engine, could become available by the middle of the decade. GE has designated the new engine study CPX38, and is basing it on the turboshaft that will power the U.S. Marine Corps’ new heavy-lift helicopter, the Sikorsky CH-53K. This could mean that the CPX38 would be in the 5,000- to 6,000-shp range.
The U.S. Air Force has selected Belac to provide turbine blades for the high-pressure turbine (HPT) first stage in F108 (CFM56-3) engines that power KC-135 tankers. The FAA-approved blades are manufactured by Oldsmar, Fla.-based Belac under FAA parts manufacturer approval (PMA) regulations. “This is the first agreement of its kind for Belac and the U.S.
Among turbofan manufacturers, Williams International remains tops with AIN readers for the support it provides to operators. Rolls-Royce, combined into one listing this year for the first time instead of being separated into R-R and R-R Deutschland, takes second place and, by barely a gnat’s whisker, bumps Pratt & Whitney Canada to third place.
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.
The air transport industry was caught off guard in April when huge plumes of ash from Iceland’s Eyjafjallajökull volcano effectively shut down flying in Europe for a week, stranding thousands of passengers and draining at least $1 billion from air carriers.
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.
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 awarded five contracts worth a total of $125 million over five years to engine manufacturers and Boeing to “develop and demonstrate technologies that will reduce commercial jet fuel consumption, emissions and noise.” The research is intended to accelerate introduction of green technology in the FAA’s Next Generation air traffic modernization program as part of the agency’s continuous lower energy, emissions and noise (Cleen) program.
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.
