3D model description

This is a 3D model of the Estes Fin Can 072614 (part numbers 072614: white, 072615: blue, 072651: magenta, 072401: green) which is a successor to the Estes PRP-1G fin can produced by Estes that has four fins. It is designed to fit BT-50 Estes airframe tubing, BT-20 tubing for the motor mount tubing, and BT-20 to BT-50 centering rings.

Estes model rocket kits that have used this fin can:

Kit# 1260 No. 2 Sky Writer
Kit# 1333 Scorpion (used 2 fin units) (later production kits)
Kit# 1993 Lancer
Kit# 2026 Athena
Kit# 2042 America
Kit# 2076 Pegasus
Kit# 2092 Mongoose
Kit# 2097 Manta
Kit# 2150 Rattler-7

There are eight versions of this fin can:
1) Original
2) Original with round fins
3) NACA-M1 airfoil (aka NACA/Munk M-1 airfoil; 6% thickness; subsonic)
More info here http://airfoiltools.com/airfoil/details?airfoil=m1-il
4) Von Karman airfoil (bi-convex; 4% thickness; supersonic)
5) Single wedge airfoil (supersonic)
6) Double wedge airfoil (supersonic)
7) Diamond airfoil (supersonic)
8) Wedge airfoil (hypersonic as seen on the Aerobee 300 and the X-15)

I have also included a paper on the fins used on Nike rockets that is in PDF format.
