In the rating codes chart in AIN’s 2004 product support survey (August, page 20), the overall average shown for Honeywell (Allied Signal/Textron Lycoming) turbofan engines should be 5.592. The value is incorrectly given as 6.592. Also, the overall average for Turbomeca turboprop/turboshaft engines should be 5.771. It is incorrectly given as 6.771.
Engine manufacturers are ready to benefit from the hot market for new business aircraft and helicopters in the coming decades. In addition to established manufacturers–General Electric, Honeywell, Pratt & Whitney Canada, Rolls-Royce, Turbomeca and Williams–several new OEMs will be introducing their own models to the market.
Well behind many other regions, and more than 10 years after initial proposals, Europe is about to rule on proposed commercial single-turbine-engine flights at night or in instrument meteorological conditions (SEIMC operations, roughly equivalent to flights under U.S.
The so-called “father of very light jets,” Eclipse CEO and president Vern Raburn, knows this new class of small jets wouldn’t even be possible without suitable engines from Pratt & Whitney Canada, Williams International and GE-Honda Aerospace. Simply, these lighter, more efficient, lower-output turbofans have opened the door to new possibilities for jet aircraft designers.
Gregg Williams, who has been president and COO of Williams International for eight years, has been named CEO. Williams, 46, is the son of company founder Sam Williams, 84, who continues as chairman of the Walled Lake, Mich. builder of military and business jet engines. Williams International, a major supplier of turbofan engines for light and very light jets, is celebrating its 50th anniversary this year.
GE Aircraft Engines recognized Columbia Helicopters for achieving 1.2 million flight hours on CT58 engines with a presentation in the GE booth (No. 3801) yesterday. Columbia received an award at the 2002 Heli-Expo when it reached the million-hour total.
In service for more than 40 years, the civil CT58 and military T58 turboshaft engine family has accumulated more than 30 million engine flight hours.
Honeywell announced that its HTS900 turboshaft engine, yet to be certified, is already getting an upgrade. The engine has been fitted with a new dual-centrifugal compressor that Honeywell said provides increased thermodynamic power capability and reduced fuel consumption, and at the same time allows for future engine growth within the same engine footprint.
Honeywell has developed and demonstrated a new two- stage compressor that promises to enable lower turbine engine fuel consumption while increasing power-to-weight ratio across a broad operating range, the company announced.
Spokane, Wash.-based Rocket Engineering is developing the Turbine P Baron in parallel with the Royal Turbine Duke program. The Baron conversion, which fits two PT6A-21 turboprops and Hartzell four-blade props to the light twin, costs about $700,000 (airframe additional). The company plans to have an STC in 12 to 18 months.
The French engine manufacturer Snecma plans to develop an all-new engine to power new business and regional jets, the company announced last month. The core engine demonstrator, called the SM-X, is expected to yield a powerplant that produces between 8,500 and 10,000 pounds of thrust, if Snecma goes ahead with the full development program. Ground testing of the core is set for the second half of next year.
