I was referring to the HAT (High Altitude Temperature) rocket, which is virtually un-documented; I have seen only one photograph (in Peter Morton's "Fire Across the Desert"), and no drawings, of a HAT round, on a rail launcher (the same one that HADs were also fired from). Its three-finned LAPSTAR second stage looked just like the HAD second stage, with the same bare-metal cone-cylinder payload fairing (or "head," as the Australians and the British called it), which contained the separating, parachute-lowered instrumented payload, and: The HAT's first stage, though, was a side-by-side cluster of two surplus British military Demon rocket motors, which were smaller than the Gosling (the Gosling and LAPSTAR were also surplus British military rocket motors; the Australians made the nose cones, interstage transitions, and tail assemblies [later Australian sounding rockets used domestically-produced rocket motors, too]). Plus: The HAT's first stage fins, which were nearly rectangular (they had long, narrow triangles "cut from" their leading edges; they were essentially "stretched-span" clipped delta fins), were attached to their rocket motors--two fins to each Demon motor--in the common "cruciform" ("+") configuration. Because the first stage had *two* rocket motors, the four fins formed an "X"--rather than a "+"--when the first stage was viewed from above or from below. The interstage transition was like the X-17's Stage 2/Stage 3 one (although it was shaped to adapt two--rather than three--lower-stage rocket motors to a single upper-stage motor)--the upper end of the transition interstage was made to accept the three-finned, single-motor (LAPSTAR) second stage.

Mark, That is scale data for the HAD . . . The HAT is, essentially, the same upper stage, but with a totally different, two-motor booster. Dave F. |

I just found an electronic copy of "Fire Across The Desert", online, in PDF format. I did not see an image of the HAT in the book ( almost 600 pages ). Dave F. |
