North American P-45 Cayuse
« on: March 25, 2018, 06:40:22 AM »
In September, 1937, the American Assistant Military Attache for Air in London, Lt Col Martin F. Scanlon, was given the opportunity to inspect the Boulton Paul Defiant and Hawker Hotspur projects.  These "turret-fighters" represented a revolutionary change in thinking in the way fighter aircraft might be employed.  Scanlon was impressed by the idea, and sent a glowing report back to Gen Arnold about the concept.  Subsequently, Arnold ordered a design competition for America's own turret fighter. 

This design competition, USAAC Design Competition X-611, was issued in December 1937 and called for a single-engined turret fighter with supercharged engine. Proposals were put forward by Bell, North American, Curtiss, Lockheed, Seversky and Douglas, but only the Bell and North American projects made it to the prototype stage, the Bell Model 17 Airaclipper and the North American NA-42.  The NA-42 was ultimately declared the winner, by which time the prototype had been designated XP-45.  The Army Air Corps wasted no time in ordering 200 P-45As, but by the time deliveries started in earnest, the Boulton Paul Defiant was proving a disappointment in air combat over Europe, and so the order was not repeated.  In the end, only 120 P-45As were delivered. 

The P-45 was radically different from the Defiant that inspired it.  Instead of a conventional aircraft with a turret behind the pilot, the P-45 used a nose-mounted spherical turret developed by the Engineering Research Company (Erco).  The twin .50-inch machine guns poured more weight of fire than the four .303s of the Defiant.  The nose position of the turret required that the engine be moved rearward, which required a twin-boom layout.  The brand new Pratt and Whitney R-2800-5 Double Wasp, developing 1850 hp was selected, along with a four-bladed General Electric propeller. 
Another feature that distinguished the P-45 from the Defiant was the fact that it included fixed, forward-firing armament, in the form of two further .50-inch M2 machine guns.   A highly unique feature was called the "Auto-fire" system.  With the Auto-fire feature selected, the pilot could hold down the trigger, but the wing guns would only fire when the turret was centered.  In this way, the pilot could focus on maneuvering, while the gunner kept his turret aimed at the target - whenever the target was directly in front of the aircraft, the wing guns would fire, adding their firepower to the turret’s.
The P-45, had it been further developed, had the possibility of exceeding the success of the Defiant, but that was not to be.  Most of the P-45s ended up being deployed to the Panama Canal zone, the Aleutians, and the Philippines, where they were either overwhelmed or ignored. 

OK, so, I had this great idea to radically WHIF a model - turns out I created the ugliest airplane I've ever seen.  In the process, I used parts from at least eight different haircraft: AT-6, P-51, PB4Y-2, F-104, A-26, B-26, Blenheim, and N1K2-J (not to mention decals from an OS2U and a P-26!)

Very original and creative concept and quite well built model.  I will agree that it qualifies as less than fully aesthetically pleasing, but not as bad as some out there.

That's phenomenal, Acree! I really like the contrast between the somewhat more modern look of the nose turret and the antiquated appearance of the rest of the aircraft. Using those "star-and-meatball" markings was inspired icing on the cake!

You have incredible vision in coming up with this concept and mad skills for being able to bring it to life!

Magnificent!

Thank you, gents!  I appreciate the kind comments.

Thanks for this historical explanation. So I have included your marvel in my collection of twin-boomers 1939-45 (at http://www.kristofmeunier.fr/twin_boom_whatif_1939_45B.htm ).
I may add a derivative today, thanks to your great view from above. I may try to Photopaint it into a twin-pod push-pull, I will try yes.

What a brilliant, 'out-of-the-box' concept.  I keep imagining it in old Swedish markings.

This is a quick-and-dirty (translation - I didn't put a lot of effort into the details) representation of the Bell Model 17, which was the losing competitor to the P-45.  Two prototypes were built.  Top view shows the first Model 17 in its delivery markings.  Lower view shows the second prototype, in which the turbocharger had been deleted, in a later camouflage finish.  Enjoy!

Oh, yeah!!  I hope, too, that the ammunition boxes are not placed immediately in front of that firewall; placing them there could cause all sorts of problems.

Thinking other ways, that tureet looks perfectly placed to be replaced by an early interation of an R2 unit.

On the Bell Model 17, how about an XP-46B Airaclipper with the engine moved forward slightly and the turret mounted behind it for better tranverse?
