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.

Business jet engine programs this year seem to be moving slowly, with little progress to report. Some–like the Snecma Silvercrest–have not been officially launched yet and are still looking for an application. Most news comes from derivative engine programs at Honeywell, Pratt & Whitney Canada and Williams International.

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.
