Blended-wing Airliner

A back of the envelope scribble says a smooth sinusoidal quatercycle
from 0 to 20 degrees bank if done in something like a half a second
would make a px sitting about 20 feet from the centerline experience a
third of a g max. I think a half second is doable -- but very
unlikely.

Sounds like mountains and molehills, or, more likely, I really don't
remember how to scribble meaningful stuff on the back of an envelope.



Well, as someone else posted, t'd more likely through turbulence, but the
thing would be FBW anyway, so it wouldn't be an issue.
I can definitely see something like this appearing in the future. In flight
anything that is not a wing is a waste, and as the Horten's proved, they
can be made to work, and work well.


But let's ask the expert,

Anthony?

The people who sit in the center section of a wide body are at 3 to 5
seats from a window. Although they may object to not having a window
they nominally pay the same as a window seated person, and if the
window seated person pulls its shade all are deprived of the view even
if sitting one seat away.

I don't think that most non-pilot care about getting a window seat - hence
the popularity of isle seats...

(I like the window so I can navigate along the flight.)

I doubt the window proximity issue will have
a serious effect on the market.

Agree

When we travel by a part 135 carrier
we choose flights based on convenience and price, and don't even
consider if the airplane is a wide body or not. Do readers of this
newsgroup consider the type aircraft when buying tickets as a primary
factor in choosing a flight?

Not me.

Cool.

Like that stops you, now? g

Do you get to access the net while in the cockpit?

That could explain all of the extra time you have to post, all of the time!

Nah, ACARS deletes flame posts.

Well, that would be one explanation....

Plus they carry six spare engines and a small internal railroad to
ferry them into position. They could swap out an engine in five
minutes. That's very reassuring!

A third of a g is what the forward acceleration of a jetliner is.

Imagine that vertically, up and down and down and up, as the plane banks
into and out of a turn.

What do building elevators do?

I chose a third of a G on a pretty arbitrary basis -- but you'd agree
that amount is much more noticable in the local vertical direction --
a direct sense of increased weight or more importantly the sense of
growing lighter -- than into the back of the seat as a PX experiences
during takeoff.

My goal was to get a sense of how realistic the issue of Gs induced by
rate of change of bank was, and have concluded (a rebuttable
conclusion) it's not a problem for realistic airplane operations. Your
comments tend to support that.

Actually, my comments are not intended to support this. I think people
would have a problem going up and down and down and up at a third of a
g. It would feel like a roller coaster ride.
