Exclamation New Nose Cones

The "USS Calypso" Design Contest winner from the 1976 Fall/Winter Centuri Rocket Times:

http://www.ninfinger.org/rockets/ca...ntercenRT4.html


...provided the inspiration for a new nose cone I designed today in *two* festive sizes. (As usual, I ended up tweaking it because the original Didn't Look Quite Right. )

They are designated BC-735J (1.00X) for Semroc ST-7 body tubes and BC-1050J (1.37X) for ST-10 tubes.


Images and RockSim files are attached below. Enjoy!

Exclamation BC-1126 Nose cone

This is a roughly 1.30X upscale of the Semroc BC-820/Centuri PNC-80 nose cone.

I used it and the new BR-1113S in the upscaled "0810" design:

Exclamation Br-1113s

And this BR-1113S is a roughly 1.30X upscale of the Centuri BR-810 reducer/transition, stretched out to 3/4" L.

I used it with the new BC-1126 nose cone in the upscaled "0810" design:
