I am looking for suggestions on the best way to model a nose cone section that
is formed as a tangent ogive (or any other ogive shape for that matter). There
would be an outside ogive solid and an inside ogive solid subtracted from it to
form the nose cone skin. For a tangent ogive, the base would be tangent to a
following cylindrical component with radius, R, and the nose cone would have a
length, L. The ogive shape is defined by an ogive radius, p, whose origin is
at the base and p>= R. (note these formulas are from Wikipedia,
Nose_cone_design)
p = (R^2 + L^2)/(2R)
The shape is revolved around the centerline and the distance, y, from that axis
to the surface is at any point, x, is:
y=sqrt(p^2 - (L-x)^2) + R - p
For my purposes, the centerline for revolution is the model x-axis and the tip
of the outer nose cone would be at x=0, but I guess this would not be the case
in general, but could be constructed that way and then the component (region)
formed by subtracting the two ogives translated/rotated to its location in the
overall model, if that is possible.
So, what would be the best way to go about this and get a relatively smooth
surface?
Thanks,
Kathy
