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 ...
While the Föppl–von Kármán equations are of interest from a purely mathematical point of view, the physical validity of these equations is questionable. [7] Ciarlet [8] states: The two-dimensional von Karman equations for plates, originally proposed by von Karman [1910], play a mythical role in applied mathematics. While they have been ...
Theodore von Kármán (Hungarian: (szőllőskislaki) Kármán Tódor [(søːløːʃkiʃlɒki) ˈkaːrmaːn ˈtoːdor], May 11, 1881 – May 6, 1963) was a Hungarian-American mathematician, aerospace engineer, and physicist who worked in aeronautics and astronautics.
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 ...
According to Kármán–Moore theory, the wave drag force is given by = ″ ″ | | where () is the cross-sectional area of the body perpendicular to the body axis; here = represents the leading edge and = is the trailing edge, although the Kármán–Moore theory does not distinguish these ends because the drag coefficieint is independent of the direction of motion in the linear theory.

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.
