Why covered landing gear? Surely the extra weight would cancel out any fuel savings from reduced drag.

Other than that it's beautiful.

Maybe in this case it dosen't.......
Also, a faired landing gear allows flight at higher speeds with the gear extended,
this means higher approach speeds, which in turn mean less reliance on heavy, draggy,
high-lift devices.

Robin.

Does the covered landing gear post-date the French FOD which killed the Concorde ??

Faired landing gear is being investigated to reduce the aerodynamic noise of aircraft in landing configuration. As far as I know it isnt an attempt to reduce fuel burn. The position of the unducted fans and the twin tails are also designed to reduce the noise emissions during low level operations.

Really impressive ! Come-back of propellers ?

Reviewing that video. Anyone else notice that the two stages of blades on the engines are turning the same way? Or is that supposed to be the case?

Actually its not a return of the propellor due two things:
- the turboprop is still used worldwide on large scale.
- the engine is actually a dual contrarotating unducted turbofan, with almost the same blade design is used in modern airliners(777,787,747-8) (heritage of the oilcrise which gave us the md-94X with the
'propfan' engines (that I just described)). The engines improve economics drastically but the cruisingspeed will be about 800 km/h.

With an ever growing customer/consumer base and a dwindling supply of "ancient sunlight", the future is inevitably slower.

Quiet supersonic transports?... I'm sure there will be a market for such things, but as long as they burn oil to create thrust I would suggest this is a foolish area for a manufacturer to invest in.

Supersonic speeds are impossible to be efficient due the engines... And the structural weight increase isn't good for economics aswel...
The designers of the Comet, one of the first jetliners, had the idea of a 800 km/h 40000 ft flying aircraft, which i guess is more realistic..
The price of the tickets must go down, so the speed and the weight aswel...
