All of the kits of the AIM-54 Phoenix that I have seen have a tangent-ogive nosecone of variable ratio. If you look at actual photos and also Peter Alway’s drawing in “Various US Rockets of the Cold War” the nosecone is definitely not a standard ogive or tangent ogive nosecone. Peter’s drawing is more like a 2:1 secant ogive from the tip to the chine, and straight from the chine to the coupling with the body tube. The pics of the real missile show the chine to be faired or rounded over to about a 1” radius. Short of turning this nosecone on a lathe by hand, does anyone know what the actual nosecone parameters would be, and if that shape is available commercially?
