Postwar Aircraft Projects / Re: CAC Postwar Projects

I only saw one file on the CA-23 at the Melbourne office of the National Archives of Australia. Unfortunately I missed the "Appreciation of Fighter CA 23 [1952]" from the private papers of H.P. Breen. The rest are in Canberra, including the very interesting looking Cabinet paper "Production of two prototypes of a long range all weather attack fighter aircraft CA 23 : Agendum Number - 129/1953 and Attachment : Date of Meeting - 20 August 1953". Which at two folios thick could be a gold mine. Alas this means I'll have to make a visit to our nation's capital.

I've data captured the 'Low speed wind tunnel investigation on the CA-23, a twin seat all weather fighter aircraft', D A Lemaire. This report details effects of various adjustments to the wing planform, flap size, with or without tails, dive brakes, etc. Primary purpose of these tests, carried out in Feb to Aug of 1951, were to explore the low tailplane position. Original position was a high T-tail, then to a position below the fin and both were destabilising.

Here a handful of AC1 pictures from the archive. The caption (actually a hand typed, half sized, tissue paper sheet inserted before the photo) of the AC1 bogged in the dried up river bed assures the reader that the tank was able to recover from this position under its own power.

In my previous post hawkeyes may have noticed the photo of nine cast hulls of Australian Cruiser Tanks stacked three up? Eight of these are AC3 hulls with a single AC1 in mid right. These hulls have been cast, heat treated and machined were needed and are ready for transport to the production line. 200 AC3s were ordered and there is an extensive folio in the National Archives of all the purchase orders that went out for all the sub-components. Then attached to each one is a 1943 dated stop work order.

The Spey-engined Mirage IV (as alternative to the F-111 to replace the cancelled TSR.2) for the UK was designated IVK.


I DO know that google books is not a panacea by any mean, this said and duly aknowledged, a lot of peope and litterature called it "the spey Mirage"

These pics are listed a Grumman model 723 on the NASA CRGIS website, but appear to be Model 623 to me.

This PDF shows that Lockheed and LTV were teamed on FX on Sept 26 1967 when discussing wind tunnel models with NASA. It also confirms LFAX4A configuration was designed prior to this time.
