XP-72 ideas

Some ideas for XP-72 I've had kicking around (and I've probably batted around when talking about Jugs in general)...

Yank the corncob, and replace it with T56.  The space for the turbosupercharger can be turned into fuel, armor, avionics bay, chaff and flare dispensers.
4x M10 37mm autocannons in the wings
3 A-10-style main wet hardpoints and maybe 3-4 smaller hardpoints per wing.
The F-106- 26 December 1956 to 8 August 1988

Sounds like the turbo Mustang idea. I say do it!
You know you want to.........

The XP-72 had a shaft-driven mechanical supercharger rather than a turbo-supercharger. The impeller
was around 3' in diameter.

I detect potential balance issues.
Allison T56 is half the weight of an R-4360. It is also about a metre longer.

You might have to give it a very long nose, especially if you want to place something heavy in the tail.

Shorten the drive shaft between the engine and propeller gearbox.

Of course you'll still have a lot of length to deal with as the R-4360-13 used on the XP-72 was
only 50" long.
;D

Seeing as the T56 already uses a driveshaft from the engine to the gearbox, install
the engine behind the pilot and use a longer driveshaft to a nose mounted gearbox.
Single exhaust coming out the side of the aft fuselage, or maybe a bifurcated pipe
exiting on both sides.
 
Perhaps shift the cockpit forward for a more modern "jet fighter" look with contra-props.

Maybe a 30mm cannon firing through the hub of a five-bladed propeller, P-39 on steroids.
That way you can keep the long nose for the ammo cans. 

:thumbsup:

Mounting options, rotate the gearbox 180 and you have an installation for a low wing aircraft.
T56 from a P-3.
