Here's the idea... Say I want to play with the shape of a nosecone, but I'm not 100% on it's exact curvature. So, I go to XYZ's website, and I plug in a few values, such as forward diameter, aft diameter, and length. Then by playing with a radius setting, I can create a fat ogive, or a shape that is nearly conical. I turned up this wiki page for more on the math behind nosecone shapes... https://en.wikipedia.org/wiki/Nose_cone_design

Anyone up for that challenge?

Thanks!
Jim

I will try, but I've already procrastinated finishing a paper long enough.

Jim, if you look at the wiki, there is a link to a spreadsheet that will likely do what you need under references.

I've used this program for several years for custom nose cones. Not quite sure if this is what you're looking for.
