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.

A nose cone is the conically shaped forwardmost section of a rocket, guided missile or aircraft, designed to modulate oncoming airflow behaviors and minimize aerodynamic drag. Nose cones are also designed for submerged watercraft such as submarines , submersibles and torpedoes , and in high-speed land vehicles such as rocket cars and velomobiles .

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.

Why is a cone mischosen? Does it have more drag than one would normally assume? Banaticus 08:27, 24 July 2006 (UTC) The conical shape has a drag coefficient of about 0.5, which is very low. However, the turbulence created with this nose cone when fitted to a rocket causes the total drag coefficient to be the worst of the shapes listed here.
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 ...
