TubLiner's Dream

I thought the main problem they envision with the wing design is that the passengers off centerline would feel acceleration forces of a much greater magnitude during turns and banks, etc. Currently, the passengers are around a maximum of 15 feet from the center of rotation, but with a BWB design of size comparable to the A380 or 747, a passenger on the outside would be around 100 ft from the center of rotation. A bank that would raise you 2 feet in window seat on a A380, would flip you up 20-25 feet on a BWB. :icon_eek: (Is the barfing smilie gone?)

Not so bad for a cargo hold, but passengers might not appreciate it - even if they could see it on the lovely HD monitors built into the seatback in front of them.

EDIT - although looking at the photoshop at the top, it appears that the passenger compartment would be only a little less than half the width of the plane, so not so bad as I spoke of above. I got my misconceptions during my Aeronautical Engineering classes when we designed a Flying Wing cargo plane with the cargo bay full span so it could be unloaded from the wingtips. That one would have been very uncomfortable.
 
not for the first time, the airlines and the FAA etc would have to agree on a set of flight envelope regulations for a specific airframe...similar to what was done for the SST types.

reduce max bank and stipulate straight in approaches or far wider patterns etc... if infact the degree of bank is as important as the roll rate.
 
The G's would be the same throughout the aircraft, but I can see the concern with the rolling motion. I think if the roll rate was reasonable, I think the ride would be fine. If you think about how long an airliner is, do the passengers in the very front and rear of the cabin get affected more by the pitching motion?

Yes, but because of the plane it's acting in it's not a problem.
