Winner, April 2003 Design of the
Kevin's entry is a creative use of parts not
normally used in this manner (the centering rings used as external detail). This
Starship is designed to use 18mm motors.
"Here's an entry for April. I
haven't buitl it yet, was just noodling around with some ideas in RockSim (file attached).
BT-50 3" (forward body)
BT-50 6" (aft body)
BT-20 3.5" (middle body)
BT-20 3x 4.25" (nacelles)
BT-20 2.75" (motor mount)
BT-80 2" (ring fin)
BNC50K or Alpha PNC
Paper transition- conical, BT-50 to BT-20, .5" long
Nose wt. (RockSim says to add 1.5 oz could prolly get by with less)
There are a lot of centering rings used in this rocket; 2 are for the motor mount, 2 to
join the BT-50 parts to the center BT-20 tube, and 3 evenly spaced on the center tube.
I'm thinking it would be much simpler to paint all the parts before assembly, especially
if you want to use a contrasting paint scheme like I've pictured.
