Default ROK Naro-1 rocket (SLV)

Hello All,

The ROK (Republic of [South] Korea) Naro-1 SLV (Satellite Launch Vehicle, see: http://www.space-travel.com/reports...ailure_999.html , www.spaceflightnow.com/news/n1006/10kslv/ , http://en.wikipedia.org/wiki/Naro-1 , and http://www.space.com/common/forums/...pic.php?t=24343 [this page has additional links and excellent photos and drawings]) would make an interesting scale or sport scale subject. It has only two fins, mounted on opposite sides of the lower first stage, so a flying model would need two clear plastic fins to provide a four-fin "cruciform" fin set.

The first Naro-1 vehicle failed to reach orbit last year when one of the two payload fairing halves failed to jettison. The second launch a few days ago failed due to some kind of problem (still under investigation) with the first stage. A third Naro-1 vehicle may be launched due to the nature of the Koreans' contract with the Russian contractor which builds the vehicle's first stage. The Naro-1 is reminiscent of vehicles such as the Thor-Altair and Thor-Burner II, which had a large liquid propellant first stage and a small, spin-stabilized solid propellant second stage. While such vehicles' satellite payloads are small, they are simple to build and fly.

Here's an additional link to the development of the first stage. The Naro-1 first stage is a derivative of the Khrunichev Angara design.

Angara
Indeed--the Naro-1 was supposed to showcase the Angara's URM (Universal Rocket Module) technology, which uses a common core module concept like the Delta IV and the Falcon 9 Heavy; unfortunately, the showcase has proved more reliable than its contents thus far. :-( (Incidentally, the Russians once looked into launching Angara vehicles from the Poker Flat Research Range [see: www.pfrr.alaska.edu ] 30 miles north of Fairbanks. One of their reasons for not following up on it was that there isn't a security fence around the facility, as it is too large to fence, and a fence would keep the moose, bears, lynx, and foxes out!)
