Hi,

the AW flying wing transport aircraft project from 1946.

Interesting design, indeed!
Is there some line drawings of this project available?

Thanks,
 
Re: British flying wing

I see that it mentions Armstrong Whitworth in the text but do we know if this is actually one of their designs or the magazine extrapolating?!

Regards,
Barry
 
Re: British flying wing

Armstrong-Whitworth AW.52 Experimental tailless aircraft to E.9/44 to test flying wing concept for large aircraft. 2 built
 
Re: British flying wing

To clarify...is the large illustration an extrapolation of AW designs or is it drawn from actual AW released artwork of the craft shape and its internal layout?!

Sincerely,
Barry
 
Re: British flying wing

There were quite a few advertisements (in Flight at least) re a project of this nature.
Not all were AW adverts so searching for them is a bit of a problem...

I have some links but have the same problem on my own system as the tags are
not directly relevant. I do recall one which was for either seating design or windows which
had a the in wing lounge.

It would seem that some pretty serious speculation and design took place in practice.
I'll see if I can trawl up the links.

What about this one? Same program or a different one?

that not aircraft,
This a flying ocean liner !

i wish they had build that craft :'(

THX for pictures
 
In the new 'Secret Projects: Flying Wings and Tailless Aircraft' book,
the author states that John Lloyd, designer of the AW.52, had hoped
the project would lead to a 'large flying wing airliner, powered by six
turbojets', but that the technical difficulties were too great.
Also, in Putnam's 'Armstrong Whitworth', it is stated that :-
"(the AW.52) would itself be but a step towards the large six-jet
airliner project being actively studied by the company..."


cheers,

Thanks for the insight. What I'd like to know is whether the difficulties experienced were due to the material limitations of the time, the over-expenditure development would generate, or if they would still be as unsurmountable today as they were at the time...
 
From the information given in the sources I've previously quoted,
and also 'British Experimental Jet Aircraft', by Barrie Hygate, and
Barry Jones's 'British Experimental turbojet Aircraft', there were
three main problems, firstly, the degree of laminar flow achieved
was very disappointing, averaging only around 5%, compared
with up to 60% achieved in tunnel tests, secondly, the aircraft's
CLmaxwas low, even with full flap deflection, due to
the short moment arm available with the tailless configuration.
This led to high downloads on the surfaces to correct the pitching
moment at low speed. This was aggravated by the extra pitching
moment generated by the lowered flaps, effectively cancelling out
their extra lift.
Thirdly, and probably most important, the aircraft proved to be
extremely sensitive in pitch. In anything other than the smoothest
air, rapid pitching oscillations would set in, which could, and did,
become divergent. On May 26th, 1949, these pitch oscillations
developed into flutter of one of the wingtips.This rapidly spread to
the whole wing,and became so violent that the pilot abandoned
the aircraft, becoming in the process, the first pilot to use a
Martin-Baker ejection seat in an emergency.
If such an aircraft was to be built today, then artificial stability
would take care of the pitch sensiivity, modern aerodynamics
would probably increase the CLmax, however, large
scale laminar flow is, I believe, still not possible, but I'm expecting
to be corrected! ;D


cheers,
Robin.

Was that related to Armstrong-Whitworth ?.

Source?
BX-27 is an fake registration and 'raketen' is rocket (there are no intakes)
Fantasy, not A-W

OK my dear Schneiderman,

and sorry for that,please Moderator,we can transfer it to a proper section.
