Wow Peter,

You're a first class artist!. These is the way I love to see unbuilt projects: alive.
Thanks for sharing your art with us :)

Cheers
Antonio


Orinblamblam your bombers book will look incredible which such gorgeous profiles

And now, the question everyone was keen to ask, but didn't... What kind of software are you using? :D
And, naturally, the pictures are super.... But anyone in Luft46 melée already knew ;D

Hi Skybolt...

The profiles are computer generated using Freehand 9 for keyline and basic drawing out and Photoshop for assembly and colour work on a Mac.
If you are interested I did a "How to do your own colour profiles" feature on Armorama, now in the Aeroscale section. I did it way back and since then my techniques and methods have developed somewhat.

Are you going to have a go?

Cheers
Peter
::) ;D ;)

Sorry to bump an old thread like this, but I spotted the pictures and wondered if anyone had more information on this 'twin-Spitfire', I mean it's obviously a competitor for the Westland Whirlwind, but what was the specification.

Not really, Westland designed the Whirlwind to F.37/35. The Type 327 was a late submission (Aug 1938) to F.18/37. IIRC, the Type 327 was meant to replace Supermarine's earlier F.18/37 submission, the Type 325 (the pusher Type 324 having already been rejected).

Well she looks a fine bird, probably not a good dog-fighter (But then the Fighting Area Attacks didn't need one). That said she might have given the bombers a nasty surprise, provided of course, her 'little sisters' (Spitfires) could keep the BF-109's away.

Makes one wish Lucasarts had done a 'Secret Weapons of the RAF'.

325 Taurus engined pusher for comparison.


Many thanks

Hi,
The Westland Whirlwind was reputed to be better than the 109 below about 15,000ft.
The Type 327 would have had about 50% more power, better at altitude and narrower wingspan.
Agreed she looks a fine bird.

From the UK National Archives - in which the entire Supermarine 327 brochure survives along with Air Ministry notes on it.

Note that total internal fuel is 220 imp gallons.

The files are clear that the armament arrangement was regarded as impractical (hard to disagree with) the pilot view was questioned (though the gunsight view was preferred compared to the Spitfire/Hurricane) and most importantly a large part of the decision making group thought turret fighters were the future and thus wanted no additional types beyond the Whirlwind, Tempest/Typhoon and Boulton Paul P.92 in development. In addition there were concerns about the design capacity at Supermarine given the number of projects they were working on and likely to bid for in future. There was also an offer to replace the cannon with 12 x .303 machine guns mounted in the outer wings but this was frowned upon because of likely scattering in the fire caused by wing flexing, although this does make me wonder whether additional fuel tanks could have been installed in the outer wings.

From, Secrets of the Spitfire.
Two captions in one, the lower one not relevant to the picture.
So, Coles caption to the image is wrong in four regards. The project has not remained unseen for decades, it has been shown many times before. The Types 324, 325 and 327 were not designed by Shenstone, as with other Supermarine projects he would have contributed aerodynamic knowledge but he was never the lead designer on any of them. The B.12/36 bomber was also not designed by him, neither was it delta winged. How do you get so much wrong in one caption?

And also radiators. Tires are large compared with spitfire.

Radiators outboard of the engine nacelles where the wing profile was much lower t/c

This includes around 1 1/2 pages of text, with original layout and detail drawings of the three types discussed below.

The Type 327 was preceded by the Types 324 and 325, in response to Specification F18/37 issued in March 1938, aimed at a Spitfire and Hurricane replacement and demanding more Brownings than you could shake a stick at. Supermarine offered the Type 324 in two options, with twin Merlins or twin Bristol Taurus radials. Alongside that it offered the same engine combis but with pusher props. All would have had the two engines rotating in opposite senses to cancel out torque. Speeds were predicted to be 10 mph more than the equivalently-engined Spitfire.
Sizes varied slightly, spans being just over 40 ft and lengths over 31 ft. The main u/c was attached behind the engines and retracted inwards into the rather thick wing. All had nosewheels.

Supermarine lost out to Hawker's two variants, which resulted in the R-R Vulture powered Tornado prototype and the ultimately successful Napier Sabre driven Typhoon. But Supermarine did not give up, picking up on the trend towards cannon with a six-cannon variant, the Type 327, and positioning it as a fallback for the Westland Whirlwind already under development. They were awarded a contract for a full-scale mock-up, but that was as far as it ever got. The Bristol Beaufighter would presently fill the gap left by the struggling Whirlwind.

The article is by Tony Buttler, as far as I can see only the "speculative rendering of a Supermarine Type 327 in the post-D-Day markings of No 3 Squadron" is by Chris Sandham-Bailey.

What strikes me especially is the big nose wheel of the mock-up which looks same size as the main wheels and looks like that of the Horten Ho 229V3 years later.
On the drawing however it looks smaller than the main wheels.
After retraction it sits behind the cockpit in vertical position, as in the later Ho 229V3.

Presumably they put the cannons in the wing roots as there was not enough space in the nose.
Lockheed did a better job when designing the P-38.

Thanks for the correction, silly me. I'll go back and update my post.

.....and just for completeness Chris' speculative rendering has an error. The exhausts from the engine were to be led back internally through the nacelles to exit at the rear. Type 327 nacelle.jpg
