I guess YORF is now, to an extent, my personal "cloud memory storage." :-) Thank you for directing me to the already-done research and the correct-size fin pattern scan! The discussion of the old Centuri launch pads and launch controllers in their current thread (see: http://www.oldrocketforum.com/showt...95&page=1&pp=10 ) included a couple of old catalog scans in which the Astrobee 350 (used as a 'launch pad model' rocket) was shown, and when I saw the Semroc Astrobee 350's too-small-looking fins (see: http://www.google.com/search?source...1.0.WWOqMT9J4xk ), it made me curious about the correct fin size--again. :-) Also:
The Dragonite's nose cone fits the ST-10 body tube (which is 1.04" in O.D. [Outside Diameter]; some of the Centuri catalogs give it as 1.0"). The Dragonite's body tube has--as the nose cone fit suggests, as I didn't measure it--the same I.D. (Inside Diameter) as ST-10, but it is thicker-walled than ST-10 (its O.D. is slightly greater, 1.1" [as opposed to 1.04" for ST-10]). That 0.03" smaller radius of the ST-10 tubing (0.06" smaller O.D., of course) would be swamped by differences of paint thickness (I wouldn't paint the bright Day-Glo red/orange Dragonite nose cone). Also--as I'd totally forgotten, but been reminded of, when I read the thread whose link you posted (to my surprise, the links that I'd posted in that old thread all still open!)--the booster of the Centuri (and now Semroc) Arcon-Hi was also made for use with the Astrobee (Aerobee) 350 and the Payloader II. |
