Hi folks,
A thread for your dedicated Commonwealth Aircraft Corporation Ideas and Inspiration.
To start with, I give you a good candidate for a scratch build.
The XP-65 was to be powered by a RA24R Avon series engine. Span was 7.3m, length was 14.3m.

And the related XP-68 - this was also to be built of stainless steel. It was to be powered by a RR Avon RA19R. It also had provision for a search radar. Armament was 2 30mm cannon + 1 missile on each wingtip + another semi-recessed under the fuselage. It was to be Mach 2 capable and was largely seen as a competitor to the F-104

Other interceptor proposals from CAC included:
The XP-46 - this was to be powered by an afterburning Avon RA-7R and was hoped to achieve 750 kts at 45000 ft. it was to be armed with two 30mmm cannon:

This was followed by a Rocket (probably using similar motors to the Bell X-1) powered interceptor, the XP-47. It was to be armed with six 3inch Oerlikon or Mighty Mouse type rockets:

Finally, there was the XP-62. This was to be a four-engined light(?) interceptor poweed by for RR RB93 Soar jets with a thrust to weight ratio of 6.77:1. Given the life of this engine at Mach 1+, it was expected that an engine change would be required after every 4 to 5 missions! It was also planned to be armed with rockets:

And who could forget the CAC CA.23 design for a twin Avon engined heavy interceptor:

I actually have a few 1/72 kits of this.

Thanks Greg, those are very cool -- especially the four-jet XP-62!
Going further back there was Fred David's Aussie Zero proposal. I've no idea what the real concept looked like so I had just bashed features from the Reisen and Boomerang to come up with the 'CA-40'. ;)
-
I have always loved that one of yours!!! :)
-
I keep thinking that the CA-23 would look stunning with a combined radar and inlet like the Lightning's; I can see that as a natural progression. Going back a bit earlier, the various potential developments of the CA-15 offer room for options. I wonder how the wings would look on a development analogous the the P.1040's evolution from the P.1035 "Jet Fury".

No mention yet of the CA-15…well, that will have to change:
First up some profiles by Damian:

And finally this one which shows that the CA-15 was certainly more than just a P-51 derivative:

Yeah, it was a bloated, plus-size derivative. ;D
-
That's what happens when you let Republic build Mustangs. :)
-
Regarding the CA-15. The prototype flew with a four-bladed prop and I can see the production version flying with a five-bladed prop on a more powerful production mark Griffon; and a racing version with contra-props. The CA-15 clearly took a couple good ideas from the Mustang but clearly was a separate development.
-
It's about the same size as a Martin Baker MB5 -- which surprisingly is nearer to a Tempest or P-47 for size. I will have to get the resin CA-15 I have in the stash built -
-
Remembering that the original CA15 was designed around big radials and the Griffon redesign was driven by supply issues. The original sketches looked like nothing else out there. I have a Stewart Wilson book on the Wirriway, Boomerang and CA 15 but its back home and I'm interstate for several weeks.

"Looked like nothing else out there"?
Dunno 'bout that, to my eye the R-2800 CA-15 kinda looks like a Curtiss YP-60E with a Mustang wing
and empennage. ;)

If you stretch it, by about 10-15% it would look similar. Personally, I liked more the proposal that looks like a Wyvern with a radial.

I keep thinking the radial-engine version would look good with a Centaurus and a five-bladed prop, as well as a racer version with a R4360.

A bit like this:

Nifty look
