Aeolus sounding rocket (photos, etc.)
Below is material (attached photographs, text, and website links) on the Australian Aeolus sounding rocket, which--due to its configuration--might make a competitive Scale Altitude model. Its second stage was the same as the second stage of the earlier version of the Long Tom, Australia's first sounding rocket. Also:
Both the Aeolus and the Long Tom are covered in Peter Alway's "Rockets of the World: 1999 Supplement," which is available from both ARA Press www.arapress.com (Jack Hagerty, e-mail: email@example.com ) and NARTS http://www.nar.org/NARTS/ (Brad Cline, e-mail: firstname.lastname@example.org ). They both also offer cheaper international postage for shipping their books than is indicated on their websites (I recently helped Australian space modelers with this); all overseas buyers need to do is to e-mail these vendors, and they will make the shipping arrangements. Below is the Aeolus scale data:

Aeolus (Latin derivation of the original Greek Aiolos) was the mythical Greek God of the Winds. The word Aiolos also means 'Quick Moving' which is quite appropriate considering the Aeolus launch vehicle was a sounding rocket initially used to aid in the development of the Woomera Range and later to study the upper atmosphere.
Aeolus was essentially a Long Tom second stage rocket boosted by seven 5 inch Light Alloy Plastic Star (LAPSTAR) motors in the first stage.
Aeolus was designed and constructed at W.R.E.
The boost motor cluster (first stage) is held at the rear by a light metal fairing which also serves as the base for the four rectangular fins, and at the front by an aluminium alloy nose casting which is faired down to the diameter of the second stage.
Mating of the two stages is achieved by a small cone on the front of the boost nose casting which picks up in the venturi of the second stage.
The Aeolus boost assembly (at left) is 16 in. diameter and 67 in. long. The total weight of the first stage is 600 lb. The weight of the second stage varies between 520 and 650 lb., which gives a total launch weight range of between 1120 and 1250 lb.
Normally the Aeolus instrument head does not separate from the motor after the completion of the burn therefore impact velocities are quite high - in the order of 4000 ft/sec with the rounds being completely destroyed on impact. However, if instrumentation recovery was required the head could be explosively separated from the motor and recovered by parachute.
If separation was required this would typically occur at a region of 150000 to 200000 feet when the round has a velocity of between 2000 to 3000 ft/sec
Seven (7) launches were made from 1958 to 1961.
Purpose: Range Development & Upper Atmospheric Research
Period of Use: 1958 - 1961
Payload Mass: 30 - 130 lb
Apogee: 240000 - 165000 ft
Ignition Motor Impulse Burn Time
Stage 1 T+0 7 * LAPSTAR 49140 lb.sec 2.7 s
Stage 2 T+16 MAYFLY 50300 lb.sec 3.6 s
I hope this material will be helpful.
