The in-development geared turbofan (GTF) has been attracting most of the headlines at engine manufacturer Pratt & Whitney lately, and it does indeed promise to make a large leap in powerplant efficiency and environmental friendliness when it enters airline service in 2013.

The FAA has adopted and/or proposed a series of Airworthiness Directives (ADs) that will affect operators of Honeywell ALF502/507 and TFE731 engines and Sundstrand APUs. ALF502L-2 and L-2C engine compressor discs may have had too much disc balance material removed, which could cause premature fracturing of the disc.

It seems unlikely that new engine architectures such as the geared turbofan or the open rotor will make it to business aviation in the near or even mid term. According to engine manufacturers, these concepts are not suited to the needs of business aircraft, which require a lot of thrust during almost the entire flight.

Turbofan engine makers active in business aviation– such as General Electric, Honeywell, Pratt & Whitney Canada, Rolls-Royce and Snecma– all have their hands full with research-and-development (R&D) programs, many of which are driven by aircraft programs. However, almost all of the engine companies also run demonstration programs that will not necessarily morph into full engine development.

One of Heli-Expo’09’s worst-kept secrets, the Rolls-Royce RR500 turboshaft engine, was unveiled Monday afternoon in a brief but hearing-impairment-inducing ceremony at the engine maker’s booth. The RR500 turboshaft, a 475-shp derivative of the RR300 that powers the in-development Robinson R66, is scheduled for certification in late 2011. A turboprop version of the RR500 was first announced last summer at EAA AirVenture in Oshkosh, Wis.

Engine manufacturer Pratt & Whitney Canada (Booth No. 624) remains committed to developing new engine products whatever the impact of the global downturn on a changing industry, according to president John Saabas. He told HAI Convention News that last year had been “a peak year” for the Canadian manufacturer.
