General parameters used for constructing nose cone profiles. Given the problem of the aerodynamic design of the nose cone section of any vehicle or body meant to travel through a compressible fluid medium (such as a rocket or aircraft, missile, shell or bullet), an important problem is the determination of the nose cone geometrical shape for optimum performance.

The last formula states that the ogive radius is greater than 2L, but the associated graphic show that L is greater than the ogive radius. In fact, L can approach 2 time the ogive radius, so the formula may have it reversed, in that L must be less than the 2 times the ogive raidus.

A drag-reducing aerospike is a device (see nose cone design) used to reduce the forebody pressure aerodynamic drag of blunt bodies at supersonic speeds. The aerospike creates a detached shock ahead of the body. Between the shock and the forebody a zone of recirculating flow occurs which acts like a more streamlined forebody profile, reducing ...
English: Render from SolidWorks CAD program of a bi-conic-shaped rocket nose cone with a total length of 18 inches, a primary radius of 4 inches, a secondary (tip) section length of 6 inches, and a secondary radius of 2 inches.
The French word ogive can be translated as "nose cone" or "warhead". The traditional or secant ogive is a surface of revolution of the same curve that forms a Gothic arch; that is, a circular arc, of greater radius than the diameter of the cylindrical section ("shank"), is drawn from the edge of the shank until it intercepts the axis.
