What shape is this nosecone?

Post by Dave Johns » Sat, 21 Dec 1996 04:00:00



I bought a 3" white blow-molded plastic nosecone at the hobby shop but I'm
curious: what is its shape? It looks ogive-ish, but with the point rounded
off at about a 1/4" diameter, but could also be a sort of sharp parabola I
guess. Anyone know what shape these commercially available nosecones are?
I don't know who manufactured it, there's no indication on the thing.

Oh, and how do you pronounce ogive? Oh-Geev? Oh-Jeev? Oh-Giv (long "i")?

Thanks!

OH-jiv (long o, short i, accent on first syllable)

Most cones of that sort are ogives with the point radiused off into a
meplat.  This removes most of the advantage of using an ogive instead of
an elliptical, but makes them much easier to mold and marginally safer in
case of a lawn dart.

I pronounce it like "OH-jive."

I had heard it pronounced "OH-jiv" and posted to that effect,
but that's incorrect. Silent is right.

The term dates back to Gothic architecture and originally referred
to those pointy arches that look kind of like... rockets.
