The Enormous UltraFan! A Rolls-Royce story.

Rolls-Royce story

I recently made a video about how the CFM RISE and Pratt & Whitney’s geared turbofan, could compete to power the planes that will replace some or all of the single-aisle aircraft that we know today. But in the comments of that video, one, or maybe two of you, wrote asking: what about Rolls-Royce? Could Rolls-Royce’s UltraFan engine, also be a part of this “engine war”? Well, the answer could well be yes, but… it’s complicated!
