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 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 ...

The 6.2 meter-tall vehicle has an elliptical nose cone at the top to protect the package from harsh conditions during the flight. [ 7 ] Unlike traditional sounding rockets that typically launch from guide rails, Agnibaan SOrTeD lifts off vertically and follows a predetermined trajectory while executing a precisely coordinated series of ...

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.
