Scott Hamilton speaks with Pratt & Whitney’s Bob Saia about the PurePower (AKA GTF). They talk about scalability, engine variants, materials, MRO/costs, and he mentions the Goodrich nacelle technologies. This last item is something not often discussed. Then they talk about a new engine for the A350. P&W has not seen any limit to the GTF thrust up to 100k thrust. We know Airbus is interested, now we know P&W is also thinking along the same lines. Then they get into noise – or the reduction the GTF achieves. At last we get an idea of what the noise reduction means in English rather than dB and stages.
