CAC CA-15 Kangaroo - Page 3 - Aircraft of World War II

Butters · 04-02-2009, 07:49 PM

The CA-15 has rather brutal good looks, but the MB.5 is flat-out, drop-dead gorgeous!

And it would have shortened the war if it had been available. Who could shoot at something that pretty? ;o)

As they say, beauty is in the eye of the beholder, beside the CA 15, the Mustang looks a little effeminite

The 485mph quoted speed for the Hawker Fury is correct. This was for the first aircraft, fitted with a Sabre engine and radiators in the wing leading edges. Max speed for the Sea Fury X with Centaurus was 460mph (probably slowed a far amount when carrying underwing tanks and racks to the 430-440mph you quote). There's some nice performance charts here.

Looks very similar in design. Gotta be some similarities in the design. However, it could be that the math just brought the engineers to the same place.

The CA looks like the Mustang's Husband.

Certainly a favourite of mine.

Someone in the thread referred to the Gov not wanting to pay for them to go into production, I think it was more the fact the jet age had well and truly come in. At the time I think Australia was receiving its first lot Meteors and Vamp's and bad timing brought its demise. I've got an article about it in 'Flightpath'. Good read.

Looking back over the drawings I first posted, the biggest similarity appears to be in the wing, at least in plan. It would be interesting if anyone has any drawings dating from it first concept (radial engine). The reason I state this is that as I have said, P51 were ultimately license built here as the CA 17 (griffon) and I am wondering if the wing was modified to copy the P51/CA17 laminar flow design?
The first I ever saw of this aircraft was in my early teens (early 70's) in a British magazine called "Aircraft Illustrated" (sadly I lost all my copies in the Clarence River flood of 1974). It was written up in an article entitled "Antipodean Venture" there was one photo, of the crashed prototype lying on its belly, and then speculation as to whether or not it was the fastest (inconclusive).
The other time it was mentioned was in the press about the same time, a large mural (no longer displayed) was painted for the aeroplane hall in the Australian War Memorial (if you do not know, there was and still is an entire Lancaster in this hall plus other aircraft, so it was a big mural in a big room, saw it, the mural, twice)
The rendering of the CA 15 can only be described as insignificant.
Original test pilot's report is still available (National Archive). As to whether is it was the fastest or among the fastest or COULD HAVE BEEN the fastest is conjectural. There is no mention (that I recall) of a genuine high speed test or combat boost ever being carried out. I use the words COULD HAVE BEEN because the fitment of a Griffon 61 was interim, it was actually proposed to use the still under development Griffon 120. The 120 went the same way as the CA 15, due to the jet age.
As for what the Sea Fury did, in practice, theory, stripped or loaded, it still was able to down one MIG (Lt Peter Carmichael, HMS Ocean) so what ever it could do, it did well enough.
Oh, and our A4Gs were supersonic too, but only if you flew them in a way that they were never flown in operationally.

Sorry this is so long winded guys, I have had a really big cup of coffee this morning

CAC-15 development

wombat40 · 04-04-2009, 08:51 PM

Thanks for the drawings guys, so the first concept was for a different wing (in plan form). It is my understanding that Wackett had a huge input into the design (it was his proposal to go with the radial) so it still leaves the question open as to whether or not the wing design was ultimately a copy of the P51 (drawn from combat experience and in my view very likely) or "an arrival at the same design using the math" as has been put. In any case, what a shame, I would still like to be rich enough and eccentric enough to commission a replica (lol)

I hear that Ian Baker from Adavnced Aero Components, Sydney Australia- is starting to construct a CA15 Kangaroo biult from original blue prints, also is restoring A46-90 Boomerang..

Wildcat · 03-16-2010, 07:21 AM

I hope so, that would be awesome!
