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.
bullet nose design incorporating a secant ogive, tangent ogive, Von Kármán ogive or Sears-Haack profile [3] the use of tapered bullet heels, also known as boat-tails [ 1 ] a cavity or hollow in the bullet nose ( hollow point ) to reduce weight while shifting the projectile's centre of gravity rearwards [ 1 ] to improve stability with ...
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 .
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 ...

Sears-Haack body. During World War II, Haack was involved in Nazi military research.His work on an analytical formula for projectile nose cone shapes that exhibit the lowest air resistance depending on caliber or diameter and length or volume and length of the profile was published in 1941 by the Lilienthal society [2] but was kept secret during World War II.

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.
