Nosecone Terms and Ratios

I'm looking an explaination (or website) about nosecone terms and the ratios.... ie ogive; conical; 4:1;5:1; etc........

If you have or can get the free version of RocSim, it is easy to see the difference as you switch between shapes based on the same measurements.

Try looking at this site https://www.geocities.com/rocketguy_101/ogive/OgiveNoseCones.htm.

What MarkABrown identified is a very good site.

Another one to check out is:
https://myweb.cableone.net/cjcrowell/NCEQN2.doc
or you can find it by googling on 'geometry of nose cones crowell'

I have reviewed both sites, thanks!!

Now, the only roblem I have is:

"MY BRAIN HURTS!!"

Have you downloaded NTSHAPE from the TripoliSc web site?
It's a DOS program that lets you vary the parameters for nose cones and transitions and then print out a table of diameters vs position along the part for progarmming a CNC or making a template.
