General Dynamics F-16 with a nose cone very close to the Von Kármán shape This observation goes against the often-repeated conventional wisdom that a conical nose is optimum for 'Mach-breaking'. Fighter aircraft are probably good examples of nose shapes optimized for the transonic region, although their nose shapes are often distorted by other considerations of avionics and inlets.
A VK nose cone is more aerodynamically efficient than a cone, ogive, or parabolic nose cone... Someone else may want to chime in with more details as to why.... Click to expand... Well, the VK nose is better at high supersonic speeds, i.e. mach 2.

April 11th, 2015. This is a model of a von Kármán ogive nose cone for a rocket that I created awhile back. Model specifics: Base radius: 4" (101.2mm) Fineness ratio: 2.5:1. Overall length: 10" (254mm) A bit of an overview; a von Kármán ogive is a particular variety of an Haack-series ogive contour - specifically, the Haack solution with minimum drag for a given set of dimensions.
