The design of new airframes always depends heavily on availability of new engine types. The very light jet segment, for example, had to wait until engine manufacturers Pratt & Whitney Canada and Williams International designed smaller engines to power a new class of light jet, and the same is true on the upper end of the market, with new large jets spurring development of ever more powerful and efficient turbofans.

In 2009 the annual Product Support Survey produced by NBAA Convention News’ sister publication Aviation International News Williams International keeps the top slot in turbofans and GE stays last, but otherwise almost all the deck gets shuffled. Among turboprop/turboshaft manufacturers, Honeywell remains on top and Turbomeca falls into last place.

GE Aviation and NASA are to ground test five sets of new subscale blades for open-rotor engines at NASA’s Glenn Research Center in Cleveland, Ohio. The tests will focus on acoustics and efficiency of a two-stage counter-rotating fan. The two partners have high expectations that new analysis tools will add to their understanding of the fan’s aerodynamics.
