I do sympathise with Keesje. Airlines wet themselves over saving 5-10% fuel so why don't they buy Keeje's Turboliner and save 20% for only slightly longer flight durations?
Nevertheless I'm still intrigued to see where Rolls' vision of the future fits in. What essentially is the difference between a turboprop and an open rotor?
It would appear open rotors can go a bit faster but turboprops can already do M0.72 at 37,000 feet. That's not much slower than a 737.
Turboprops have gears but then again it looks to me as though Rolls' motor has a gear to get one of the rotors to counter-rotate.
Rolls has failed to win anything recently with their RB285. Is open rotor just to divert attention from their weakness in the narrow body market?
