Blended-wing Airliner

Thirty Five percent more fuel efficient. That would translate into

Boeing ever build something like this? Or will they wait until Airbus
or Embraer or the Chinese or the Russians build one?


More likely, same price tickets and fatter profits for the airlines.
We've discussed this design (beat it to death, actually) in an earlier
thread. The big problem seemed to be with pax comfort (lack of windows
and vertical acceleration for outboard seats during turns) never mind
the pressurization issue.

Looks cool in photos though G

In the late 40s, when Northrop was building the YB-49 jet powered flying
wings, they put together a mock up of a civilian airliner version. I
remember seeing a promo film about it, which can probably be found floating
around the web somewhere.

Northrop solved the problem of passenger claustrophobia by making the
leading edge of the wing transparent. The passengers were seated in a
theater-like arrangement and could see where the plane was headed.

That was back when passenger planes were very noisy, and not too fast.

I can see a leading edge bird strike at 250 knots +. It would bring a real
meaning to the word messy.

The noise of a transparent leading edge would be something else, too. All
of the wind whistling around the leading edge would really make some noise.
It might work if it were an inch or so thick, but we both know what that
would be. Heavy, and expensive.

All we need is transparent aluminum, like enough to replace the 16" of
Lexan, as they wanted in the Star Trek movie.

I think if the G loads were not too much for passenger's comfort while
banking, (I'm not convinced they would be, without some real good math
proofs that I'm not good enough to do) I think viewscreens in front of each
passenger would be a great trade for the window view. I hate to not have a
window seat, and it would make me happy to have a view out of any of the
several cameras I chose to view.

Those are the military versions. The one I'm talking about is a ~10 min.
promotional film put together by Northrop, using the civilian airliner mockup
and showing off the "advantages" of the flying wing airliner of the future.

I might have it somewhere in my archives. If I locate it, maybe Jay can
host it on his site.

And, appropriately, it was on the cover of popular mechanix or one of those
around the time it was designed.

I'd love to have flown it..

Imagine very nervous fliers when the plane pops into a cloud?

A crosswind landing would be worse. A few years ago I flew in a SAS
plane with a forward-looking camera installed. Passengers could see
everything pilots saw. I loved it, but I can understand why it was
discontinued. For someone who never piloted anything it IS scary when
the plane is pointed away form the airport.
