Ogive Nose Cones

David Stribling (Rocketguy101 on TRF) wrote a great article explaining the shape and formula of Ogive nosecones.

If you didn't know, a 3:1 nose cone simply means:
The nose cone length is three times the body diameter.
A 4:1 nose cone length is four times the body diameter, and so on.

Roy Green (SpevATL on TRF) added this:
An ogive is described by the intersection of two circles. If the center of those two circles falls on the shoulder line of the nose cone, the shape is a tangent ogive; if they fall on either side of the shoulder line, they are secant ogives.The best discussion I've found is http://en.wikipedia.org/wiki/Nose_cone_design

I never got into the math when picking out a nose cone.
With so many shapes available I just hit the "Add To Cart" button.
