Default HAT (Oz) sounding rocket data?

Hello All,

Does anyone have more material on the Australian HAT (High Altitude Temperature) sounding rocket than *this* https://space.skyrocket.de/doc_lau/hat.htm photograph on Gunter Krebs's website? The HAT used the same second stage--a LAPSTAR motor with three Aerobee-Hi/150/200/300 sustainer-like fins (although much smaller than the Aerobees') and a cone-cylinder payload housing--as the second stage of the HAD (High Altitude Density) sounding rocket, and:

The HAD (see: https://space.skyrocket.de/doc_lau/had.htm and https://www.oldrocketforum.com/show...light=Carnarvon [it is also covered in Peter Alway's "Rockets of the World"]), which usually deployed a 6' (or 2 m) diameter aluminized polyester plastic film Arcas (or was that Arcis, or maybe Arcus...? :-) ) ROBIN-type balloon payload at apogee, for radar tracking of the edge-of-space winds, and thus the air density (although some HAD rounds carried instrumented payloads instead), used a Gosling first stage motor. But:

The HAT, whose first stage (two, clustered Demon rocket motors) was less powerful than the HAD's Gosling, carried a parachute-lowered, thermistor-sensor payload, which radioed the atmospheric temperature to the ground station. (These tidbits of information are from Peter Morton's 1989 book "Fire Across the Desert: Woomera and the Anglo-Australian Joint Project 1946 - 1980.") Also:

Some of Australia's sounding rockets are hardly covered at all, and the HAT is one of these. With the people who developed and used these vehicles now passing from the scene, the window of opportunity for documenting their development and use--not to mention the inspiring, and often-humorous, personal stories about their pioneering work--is rapidly narrowing. If not preserved, their stories will die with them.

Many thanks in advance to anyone who can help!

Unfortunately, I have nothing on the HAT.

Hopefully, Peter Alway or Chris Timm will respond, as well.

I share that hope; someone on the Australian Rocketry Forum (or in the town of Woomera, which was created to support the range proper and still exists; many of its residents work or worked there) may also have such material. (One of the Australian Rocketry Forum Members, who had worked at the Woomera range, posted personal photographs he'd taken of the Redstone-based SPARTA WRESAT vehicle, which orbited Australia's first satellite.)

If I had more than the sort of vague stuff you've already found on the HAT, I'd have drawn it by now! I'm not sure what I have on file at home, but it's nowhere near enough to do proper data for it.

Thank you, Peter. I'll see what--or who--I can find. Having had a close call myself, I was reminded (by my doctor, too) that I might not have a whole lot of time to "let slide" regarding this, either. Could you post a list of Australian sounding rockets you could use data on?

The advantage with them is that there wasn't a huge number of them, and not a great many variations of the various types, either (there were two Long Tom and HAD variants; the later HAD vehicles used a simplified first-stage fin assembly, where the fins were affixed directly to the Gosling motor's nozzle [the Cockatoo used that fin attachment method, too]).

I'm not getting any younger either. My contemplation of mortality is telling me that I've got a half-dozen or so Australian rockets covered, and I need to use my limited time on things I don't have covered so well. So I will encourage you to follow your own obsessions!

I'm concentrating on US Navy missiles once I get back to artwork next month, and after that, there are under-represented countries I need to work on (I only have one Chinese rocket drawn outside of a couple of ancient black bowder rockets, for instance).
