If I recall correctly the Concorde used about 2 tonnes of fuel rolling on the ground alone.. I wonder how this new aircraft fares for fuel consumption? I believe the Concorde is a marvel. You could travel faster than the rotation of the earth in it! However I don’t think we need more environmentally unsustainable travel.
It's hard to say how efficient this plane will be before it's built (or more details made public) but from what I've read sofar the big version, 'Boom Overture', is meant to use turbofan engines. That alone should provide significant fuel savings over the Concorde, which used turbojet engines with afterburners on takeoff. Even so, supersonic flight is less efficient than getting there a bit slower. Unfortunately, air…
To be clear, that's wrong, because of other factors; when you go faster in a given airplane, you can be more efficient at higher altitudes - mindful that wing size is dictated more by landing speeds than just how fast you want to go - if anything, you want smaller wings for weight, cost, and other considerations, but landing speed gets in the way. So, if you took the time to solve that equation for an airplane at, say, 30k feet, and for say 50k feet altitude, would you still get efficiencies over say, one of the modern , slower jumbo jets?
