The debate about the design of future commercial aircraft engines broadened this year as concerns mounted over the effect aircraft engines may be having on global warming, while the cost of aviation fuel rocketed and noise became ever more of an issue.

“Welcome to Lear Jet Country,” a marketing slogan that attached itself to the early-20-series Lear Jet, is likely to be remembered only by industry old-timers who recall the airplane’s ability to take off and climb to 41,000 feet without effort. It is a capability that disappeared with the advent of the Learjet 35/36.

Pratt & Whitney Canada and the French-Russian Snecma-NPO Saturn joint venture are knocking at the door of the market for regional-jet turbofan engines. The geared-fan PW800 and the more conventional SM146 are not yet fully launched programs, but development is well under way.

Emergency AD 2003-08-52 was issued last month for the GE CT7-9B turboprop in response to 12 compressor-stall events in Saab 340Bs over a six-month period. The stalls occurred when pilots throttled back from takeoff power to climb power. Nine of the events involved engines that had the compressor variable geometry (VG) rigged to N1, one of two allowable rigging options that affords slightly higher performance at the expense of stall margin.

For aviation, the spirit of the 1950s could be said to have begun with Chuck Yeager’s breaking of the “sound barrier” in Glamorous Glennis, a rocket-powered Bell X-1, on Oct. 14, 1947. The World War that had dominated the first half of the 1940s was receding in memory, and mankind’s focus on ascending from the rubble was illustrated clearly by the advances in aviation.

Pratt & Whitney Canada’s PW610F turbofan engine will power the Eclipse 500, the two companies announced on February 19, ending nearly three months of speculation about how Eclipse would get the program moving again after it terminated its agreement with Williams to use the EJ22 engine.

When Charles Lindbergh began planning one of the first truly long cross-country solo flights in 1927 everyone understood the risks inherent in a 3,000-mile journey in an airplane powered by a single 223-hp Wright J5 engine. Failure meant he’d probably end up as a shark snack. Luckily, he didn’t have the boss on board.

Teal Group announced the results of its market analysis for the turbofan industry, predicting a total of 40,989 turbofan engines will be built in the 10 years spanning 2004 and 2013. Teal estimates the value of the engines to be about $160 billion, up 1 percent from last year’s 2003-2012 market forecast.
