ah, neat! looks like they recently switched from 3x turboprop to 4x turbofan edit: had to correlate sources to find that a bunch of popular aviation blogs got the original design wrong. was actually 3x turbofan -> 4x turbofan

why the downvotes? the original design was trying to use 3x turboprops, and i can see articles on google about them switching to 4x turbofans after the xb-1 work edit: see parent edit, i was wrong. you guys are pretty good at making someone with misinfo feel bad though

The original design was meant to use 3x turbojets, not turboprops.

Overture is being designed to carry 65 to 80 passengers at Mach 1.7 over water — or twice the speed of today’s fastest commercial aircraft — with a range of 4,250 nautical miles. Optimized for speed, safety and sustainability, Overture is also being designed to fly more than 600 routes around the world in as little as half the time. Flying from Miami to London in just under five hours and Los Angeles to Honolulu in t…

CAN-LAX is 6,284 nm.

OK that can work, CLE-MUC is 3,759 nm.

I wonder if a transatlantic hop on this, with electric flight on either end can work to replace direct transatlantic flights while being faster and greener? Probably all depends on the switchovers.

This will be hardly greener than taking a regular aircraft.

Not only very expensive, but basically coach class all the way through, even for the rich people.

Concorde was not very pleasant to sit in from what I've heard. Great food, but the seats were basically economy 2x2.

it's all turboprops and no afterburner. so, expensive, but much more affordable than concorde, maybe to the point of competing with subsonic first class

Turbofan (what's on most commercial jet aircraft), not turboprop (jet engine driving a propeller, generally on smaller commercial and some private aircraft).

r/noStupidQuestions ;

Can these be 'stacked' - Can you have a turboFan in line with a turboProp such that the output of the wash of the Fan feeds into the Prop, but with a portion of the wash spinning to thrust on the outer ring of output.=, via a design in the cowlings which is hyper directed thrust vents (think the grid of straws used to funnel water into a cohesive column, which can be directed)

Imagine a small diameter turboprop behind a much larger turbofan

You have to be mixed up; a turboprop has a propeller attached to the jet engine. No-one in their right mind would use a turboprop supersonically. It would make an insane amount of noise.

I find it incredibly hard to believe that turboprop was ever on the table.

American would swap this in for a plane which is using an existing takeoff/landing slot. Heathrow is also passenger-capacity-constrained right now, but that's more to do with understaffing.

> American would swap this in for a plane which is using an existing takeoff/landing slot Have to be charging a great deal to the small number of passengers for it to be worth swapping in to a fully loaded 777 spot

Move all the first pax to the boom aircraft and do all economy/premium economy in the 777 and you’d come out even in the number of seat miles available.

You could also upgrade a couple of the 777-200 or 787 routes to a 777-300 to get more seat miles to offset those lost to loosing a slot to a smaller aircraft.
