It's also about 15 percent more aerodynamically efficient than conventional aircraft. At full scale, the Flying-V would seat 314 passengers in two classes.</p></div>

It is a computer generated image, anyway.Brucemorrow wrote:They are windows.
Here is an image of the actual scale model:
The layout is a lot more unconventional than the view of the cgi suggests. Its planform is a rather sharp V.

One of the problems with flying wings for human cargo, is the further away from the fore to aft center line (roll axis) that the passenger seating is, the more unpleasant it is for the passenger during banking turns, rolls and/or turbulence. Ok for slow slow turns and smooth air, or carry plenty of barf bags. Or they could charge extra for the 'roller coaster' seats.

The video of the test flight mentions sensitivity to dutch rolls. This kind of missbehavior is already challenging to the passengers in regular airliner. I imagine, it would be extra bad in the back end of the flying V.UnTuckable wrote:One of the problems with flying wings for human cargo, is the further away from the fore to aft center line (roll axis) that the passenger seating is, the more unpleasant it is for the passenger during banking turns, rolls and/or turbulence.

If I recall correctly, there is already an dutch roll dampener active by default in current Boings or Airbuses. So the engineers may see this as a challenge rather than as a road block.

Dutch roll = wing-over ?
So I was watching airliner commanders explaining their reaction to the Dutch roll. It made me wonder, whether hang gliders also show this kind of behavior. After all, our wings are strongly swept back , too.
Could it be, that the movement we call "wing over" is our version of the Dutch roll?
