Nose cone ( center of the spherical nose cap)

Description

The nose cone section of any vehicle or body meant to travel through a compressible fluid medium (such as a rocket or aircraft, missile or bullet) is designed in several geometrical shapes for optimum performance. In practical applications, a conical nose is often blunted by capping it with a segment of a sphere. The center of the spherical nose cap can be calculated by the coordinates of the tangency point where the sphere meets the cone and the radius of the spherical nose.
