Airbus appears to be warming to Pratt & Whitney’s geared turbofan – and not just for technological evaluation on its A340-600 flying testbed. Only two months ago Airbus was pretty adamant that the GTF would not be considered for future A320 variants but now COO John Leahy, asked by my colleague Robert Wall, seems to be changing his tune. The concept is apparently achieving critical mass, and is becoming “real” thanks to the MRJ, CSeries and the recently begun flight test program. Depending on results of flight tests it seems a variant of the PurePower PW1000G could well be offered as an engine option on the family. Integrating the engine would take between two and two-and-a-half years says Airbus.
The translating aft cowl section of the nacelle is being used to vary fan pressure ratio during flight tests. A version of this feature could one day appear on production engines.
