Very nice!!  Shifting to a more Mustang-style radiator installation?

It's like if you asked Sergio Leone to make you a Mustang!

Wonderfully imaginative, apophenia!

Thanks folks!

Retired In Kalifornia - Excellent rendition of the Re.2001 Delta  :smiley:

What about a RR Griffon-engined variant?


Thought about that but then got distracted by the Out of Africa GB:

This is an unbuilt project turned whif. The Bell Model 11 was a pursuit/interceptor concept of circa 1938-39. It seems to have been an unrequested submission to the USAAC but I'm not sure whether it was meant to answer a particular specification or not.

The Bell Model 4 Airacobra had been ordered as the XP-39 in October 1937 and a prototype was due to fly in April 1939. However, no series had been issued in late 1938 and perhaps Bell was getting nervous. Bell's object in designing the Model 11 must have been to offer a simpler, lighter alternative to the P-39. Overall, the Model 11 gives the feel of an American Bf 109 analogue.

The top view is based on Bell Aircraft's 3-view general arrangment Drawing 111/1001 of 06 July 1939. On the copy I have, the specs are hard to read but seem to say 1,040 hp (but probably 1,050 hp) Allison V-1710 V-12; weight 4,352 lbs (empty), 5,585 lbs (gross); length 26' ?"; wing span 30' 0"; wing area 160.5 sq ft; Section NACA 21-C3 (root), NACA 27-104 (tip). No details are shown for a retracted undercarriage ... so I guessed (based on the odd leg placement and a 'swollen' inner wing profile). There's no real indication of intakes for carb or cooling (I'm guessing P-39-style rads  buried in the wings, oil coolers may be in lower cowling, but carburettor ...?).

The bottom view is a Bell P-45B - my whif of what the Bell Model 11 might have looked like in service. Some changes have been incorporated from the XP-45 above. First, stability was enhanced by increasing wing diherdral [1] and balance improved by moving some of the consumable fuel into the wing. That was possible by relocating the coolant rads into a belly fairing (based upon that of the Curtiss XP-46). Armament has been increased to four .50-calibre Brownings - two synchronized and two in the outer wings. [2] A P-40-style carburettor intake has been added between the cowl guns for the V-1710-33.

I also modified the cockpit canopy in shape and to a sliding type. Partly this was to increase the opening size, incorporate a glass-armour windscreen, and to just look slightly more like an Airacobra ;)  Too late, I realized I'd created problems with the markings. Anyone care to guess what they are?
__________________________________________

[1] I've also rounded the tips Airacobra-style in place of the original Model 11's tips which were 'clipped' on an angle.

[2] I'm assuming that the original Model 11 would have had the usual pre-WW2 USAAC pursuit armament of one .30-cal and one .50.

Beautiful!!  I can't help but wonder if the original concept drawing had the carburetor airflow coming from a NACA-scoop on the top cowling; it would work but it wouldn't necessarily be as efficient as needed.

From a point of pure ignorance, I'm going to guess that you had to move the markings below the rear cockpit glazing back & up to get them off of the canopy rails.

That'd be my guess too after confirming the number of rudder stripes (13) are correct. That's the most typical inter-war USAAC markings "miss".

What a beauty and it's not hard to imagine this on the flight-line! Well done apophenia! You always seem to top yourself with each new creation!

I have stumbled on to your stuff from time to time and never, until now, got a chance to say how much I admire it.

Sensibly, Small Brown Dog doesn't sweat the technical details too much. I don't quite understand those details which are provided, so I've just made up my own ...


I will explain more in a new topic

PS, I screwed up the quote thing  - oops :(

It's cool, SBD, the "quote" thing can be a touch tricky on this site. For some reason it won't let me add a quote once I'm in the reply box but it will allow me to start a reply by clicking quote.

It's all too techmamologimacle for me! :-\

Cheers folks!

Evan: I like your NACA scoop intake idea. It may not have been as efficient, but it sure would've looked cool  :smiley:

Markings: I must admit that I didn't give too much thought to the exact placement of the fuselage roundel ... or a specified diameter. (I really must dig out my copies of Dana Bell's Air Force Colors books!)

I based my P-45B at Rekyavik sometime after the US took over the defence of Iceland in mid-1941. But the red 'dot' wasn't ordered removed from USAAF roundels until 28 May 1942  :P  I suspect that fuselage roundels may not have been worn at that time in any case ... fortunately, its a whif :)

SBD: Welcome aboard Small Brown Dog! I've admired your work too. And by 'admired', of course, I mean that I've stolen your concepts shamelessly  :-[

I saw my name come up in a search actually because I was looking for some git on Flickr or something that has stolen a pic and renamed it but in so doing I found this place. I have no problem with "borrowing" as A: you give credit and  B: your skills and imagination are several light years ahead of needing to steal stuff. However, having gone off on your own story line re the tech I figured I best sort that out :)
I was building a website for all this but to be honest I can't be bothered because I have had a gut full of web development in the past. Besides, this seems like the ideal place to put the content ;)

It is indeed. And no need for SEO, we on the lunatic fringe are already here  ;D
_____________________

With this next one, I spun off on the idea of the Bell Model 11 being inspired by the Bf 109. That involved a  Messerschmitt-style main undercarriage (instead of Bell's odd-to-me landing gear approach). And, of course, nothings says Messerschmitt like an inverted V-12. So, in went the Continental IV-1430 'Hyper' powerplant.

The XP-45 Hypercobra' prototype shows a standard Continental IV-1430 engine with no armament fitted. Compared with my first go at a Model 11, this one has a more P-51A-style belly radiator. As shown, an updraught carburettor is fed by a chin intake flanked by twin oil coolers. Planned armament for the production P-45A was a 25 mm motor-cannon and twin synchronized .50-calibre machine guns. However, insoluable feed problems led to the abandonment of that cannon.

The production P-45B was armed with only the two machine guns. Although it's not tremendously obvious, the rear fuselage has also been extended - mainly to better balance that long nose. This fighter is having temporary, water-based paint 'Red Force' markings applied for the November 1941 Carolina Maneuvers. The red spinner tip is a squadron colour (for the 35th Pursuit Squadron) as is the fuselage Command Band indicating that this is the 'A' Flight Leader's aircraft.

Permanent national markings are as per Air Corps Board Specification 24114 of October 1940 - with less glossy roundels on the fuselage side, underside of port wing, and upper side of starboard wing. Tail stripes have been omitted. 'US Army' is painted on the wings' underside with Insignia Blue paint and Individual Aircraft Number ('4') and squadron designator ('31P') painted on the fins (albeit, in lo-viz black rather than the specified yellow).

Cannon armament would not appear until the P-45C model. There, the main armament was a 20 mm Browning M12 - a reinforced M2 gun firing 20 mm Oerlikon shells from necked .50-calibre cartridges.
