A projectile has a front portion and a cylindrical portion. The cylindrical portion comprises a cylindrical sidewall having an outer surface and an inner surface. The projectile also has a plurality of depressions in the cylindrical sidewall. The depressions have an outlet adjacent the second end, an inlet toward the first end and a neck area between the inlet and the outlet. A width of the inlet is smaller than a width of the outlet. The depressions at the neck area have a curved sidewall, but a generally straight sidewall between the neck area and the outlet. The surface of the depression extends at a ramp angle from the outer surface of the sidewall at the inlet of the depression toward the inner surface of the sidewall at the outlet.

A system, apparatus and method for mitigating the shock front of a rocket or aerospace plane flying at hypersonic speeds while simultaneously distilling liquid chemical elements regeneratively from the ambient air by means of vortex inversion splines. The splines may additionally be tuned by geometry to function as both centripetal and/or isentropic thrust augmentation attribute and/or double-decker Joule-Thomson refrigeration means. Because of the stochastic stagnation flux that reaches into the absolute zero zone by means of precooling, a splined stochastically switched hypersonic nosecone may be constructively tuned into a complex Carnot refrigeration engine commanding both personal and enterprise liquid Helium distilling means with orders of magnitude efficacy gains over existing methods.

The invention relates to a projectile (1) having an elongated body extending in a longitudinal direction (2), comprising a nose portion (3), a base portion (4) and a middle portion (5) connecting the nose portion (3) and the base portion (4), wherein at least one of the nose portion (3) and the base portion (4) and/or the middle portion (5) comprise structural surface arrangements forming an aerodynamical effective surface (7) and/or a sealing arrangement comprising a plurality of ductile annular sealing areas (8; 9).

An ordnance for air-borne delivery to a target under remotely controlled in-flight navigation. In one embodiment, self-powered aerial ordnance includes upper and lower cases. A plurality of co-axial, deployable blades is powered by a motor positioned in the upper case. When deployed, the blades are rotatable about the upper case to impart thrust and bring the vehicle to a first altitude above a target position. An explosive material and a camera are positioned in a lower case which is attached to the upper case. The camera generates a view along the ground plane and above the target when the ordinance is in flight. When the vehicle is deployed it is remotely controllable to deliver the vehicle to the target to detonate the explosive at the target. The ordnance may drop directly on a target as a bomb does.
