“Advance lays down the architecture we're going to take forward to the next phase” Newby says, referring to the UltraFan. The concept will be the first Rolls large turbofan to incorporate a fan-drive gear system or “power gearbox,” as the company calls it, and is the first significant change to the traditional three-shaft layout since the advent of the in the 1960s. The feature “earns its way” onto the UltraFan because of the engine's relatively large diameter fan, Newby says. “This gives the LP turbine a significant challenge and to mitigate that we have a reduction gearbox,” he adds. The revised configuration retains an effectively unchanged HP spool and a conventionally connected intermediate spool. However, unlike any previous Rolls design, the UltraFan will interpose a gear system between the IP compressor and the fan. The design therefore does not include an LP turbine.

As someone who deeply enjoys both dudes’ styles of play, it’s a cool drop of relief to see them shut up the skeptics and sustain good tennis for a whole week to make a final of this magnitude. But as someone who has watched both long enough to know, I would not go so far as to confidently project big things for either at the . Open, which begins next week. They’re just a little too volatile for any bold predictions. Just hold out modest hope and believe it when you see it. The unending Federer-Nadal show has been pleasant enough, but, c’mon—let them duel for year-end No. 1 and leave this dang thing for someone else. It’s bizarre to see it in writing, but in 2017 the most radical outcome might simply be someone in their 20s lifting a major trophy.
