Armstrong Whitworth civil aircraft projects 1934

[Schneiderman]

Prior to finalising the design of the AW27 Ensign Armstrong Whitworth worked on a number of alternative airliner types

 

[PMN1]

The narrowing towards the tail of options 2, 3 and 4 seems a bit excessive wasting potential space at the rear of the aircraft and wings look thick enough to walk an elephant on.

Amazing Projects Schneiderman,

but can I ask you that,during middle of 1930s,the Type numbers was appeared,did
those airplanes belong to it or not ?,please see;

What were the seating arrangements, 2 looks like a 1 + 1 while 3 and 4 look like a 1 + 2.

There is no indication on the drawings and all the numbers between AW15, Atalanta, and AW27, Ensign, appear to have been assigned to known projects. I suspect that they are early concepts that were not given official project numbers

Yes, that is correct

 

[hesham]

Thanks.

The fuselage construction looks to be the same as for the AW15 Atalanta rather than the metal monocoque adopted for the AW27 Ensign.
I also just noticed that the original drawing dates are November 1933, signed off in March 1934.

Image from Putnam - Armstrong Whitworth:

From, Kites, Birds & Stuff - Armstrong Whitworth Aircraft.

It is usually helpful to provide title and author:
Kites, Birds & Stuff - Armstrong Whitworth Aircraft by P.D. Stemp, Lulu.com 2009

Tapper mentions a scaled-down version of the A.W.XV Atalanta with two [140 hp] AS Genet Major engines, yet his drawing clearly shows four engines. The full-scale AW Atalanta was powered by four 340 hp AS Serval engines. I guess both Tapper and Putnam's editor overlooked that glitch.
Tapper's specifications match those provided (copied, I suspect) by Stemp.
<edit> the same design appears in reply #1, first image

 

[PMN1]

So, the cargo aircraft is still an unknown?

Its bigger than a Shorts Skyvan which used two 715hp engines so I cannot see it doing anything but rolling along on the ground on two Genet Majors.

@PMN1 See reply #11: design of 1958 for a short-range car ferry.

Dimensions in the drawing are wrong.....is there anything in the drawing that is correct??

 

[Arjen]

Stemp's drawing <edit> now deleted </edit>, copied from Tapper, shows the car ferry, its drawing's caption gives dimensions for the scaled-down Atalanta which turned out to be quadruple-, not twin-engined. Tapper made a mistake in an otherwise very nice read, Stemp repeated Tapper's mistake, compounding the mess by copying the wrong drawing. Stemp wasn't paying attention.

Other than that - everything tickety-boo.

In reply #9, Stemp's drawing, copied from Tapper, shows the car ferry, its drawing's caption gives dimensions for the scaled-down Atalanta which turned out to be quadruple-, not twin-engined. Tapper made a mistake in an otherwise very nice read, Stemp repeated Tapper's mistake, compounding the mess by copying the wrong drawing. Stemp wasn't paying attention.

Makes sense.

Well here is a 2-engine version of the AW15 from an original un-numbered Armstrong Whitworth drawing with a tracing date of March 1934

Away from my bookshelves, but ISTR that's a Britten-Norman freighter design - Mainliner? - (if not that then a grown-up Skyvan), covered in Stuck on the Drawing Board by Richard Payne.

Seems to be an error in that source. Quite obviously not a pre-1945 project, I think.
We should go on with it in a thread in the post-war section, if there's the need.

Excellent. Caption in drawing says two Tiger engines, which makes a lot more sense than two Genet Major for an aircraft this size - length 71 ft 6 in, span 90 ft. The same dimensions as the four engined AW15.

There was a BN-4 Mainlander proposed. Four engines.
