Turbomeca chairman and CEO Pierre Fabre knows that for his company to grow and prosper, it is not only necessary to sell engines to helicopter manufacturers that deliver all over the world but also to allow engines to be built in countries like China. But it is naïve to think, Fabre said, that there is no risk of losing control of intellectual property when engines are manufactured by non-Turbomeca-owned entities.
The European Aviation Safety Agency (EASA) yesterday withdrew requirements for repetitive Rolls-Royce Trent 900 inspections it mandated following the uncontained failure of a Qantas Airbus A380 engine last November. The relevant airworthiness directive (AD 2010-0242R1), which applies to all examples of seven engine variants, follows “further assessment of manufacturing data and additional stress analysis.”
Chromalloy is offering a new thermal barrier coating it claims enhances the performance of gas turbine engines. "The RT-35 Low K coating provides lower thermal conductivity, which allows higher engine temperatures. Engines produce greater thrust when operating at higher temperatures and they can operate on the same amount of fuel as powerplants that operate at lower temperatures," said Dr.
A new 150,000-sq-ft investment casting facility has been opened in Tampa, Fla., by Chromalloy Castings. According to Tom Trotter, v-p and general manager, it is the only facility in the world that can investment cast aerospace gas turbine blades from the smallest up to and including large, heavy industrial gas turbine blades and vanes other than those made under contract for the OEMs.
“It’s about life-cycle cost management,” Tom Trotter, v-p and general manager of Chromalloy Castings, told AIN about the company’s new 150,000-sq-ft investment casting operation in Tampa, Fla. “We are now able to offer the industry a single source for engine component design, engineering, tooling, machining, repairs, coatings and now castings,” he said.
The Pentagon has selected Emteq to study the feasibility of a rotor blade tip lighting system that can be modulated to provide navigation lights at the appropriate azimuth positions, mark the complete rotor disk in hover mode, and provide a low-observable NVG mode for night formation flying.
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.
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.
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.
Loss of engine power during landing approach due to a fatigue fracture in a power turbine blade caused the fatal helicopter crash, according to the Board. N67GE, operated by Island Express Helicopters, was landing on Santa Catalina Island at the end of a Part 135 flight from Long Beach when witnesses heard a “pop” sound and saw flames emanating from the back of the engine. The helicopter then crashed and was consumed by fire.
