Something I've been wondering for a while is how to mathematically describe the shape of the cut-outs on the Saturn 1B's scalloped transition (intersection of a cylinder with a cone with central axes parallel). If there are any mathematicians (differential geometricians?) that might be able to explain how to figure out the shape, that would be quite cool. The shape is very close to an ellipse (I've always used ellipses to approximate the shape when making the parts [minor axis being the diameter of the tube, with the major axis figured with trig based on the angle of intersection], and it's worked well enough) but I'd really like to know what that 'perfect' shape is.
