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 .
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 ...
Artist's rendering of a payload fairing being jettisoned An example of clamshell fairing of Falcon 9 during testing, 27 May 2013. A payload fairing is a nose cone used to protect a spacecraft payload against the impact of dynamic pressure and aerodynamic heating during launch through an atmosphere.
On 25 March 2021, two Hwasong-11C (then unnamed) were first launched. The missiles are longer, with a more conical nose. North Korea claimed that the new version flew 600 km (370 mi) and is equipped with a 2,500 kg (5,500 lb) warhead, although South Korean and Japanese analysis initially said they only flew 420–450 km while reaching an altitude of 60 km, and such a large warhead weight is ...
An older design model on display at the U.S. Space & Rocket Center in Huntsville, Alabama; note the conical nose and single-dorsal fin tail that distinguishes it from the newer model. A newer design mockup on display at the Aviation Challenge campus of the U.S. Space & Rocket Center in Huntsville, Alabama; note the flat, duckbill nose and ...

In particular, the design featured a conical nose, for low supersonic drag, [24] and sharp wing leading edges. The design used very thin wings of biconvex section proposed by Jakob Ackeret for low drag. The wing tips were "clipped" to keep them clear of the conical shock wave generated by the nose of the aircraft. The fuselage had a 5-foot ...
