摘要： The invention relates to a bullet which includes a bullet-shaped body having a forward-facing central cavity with at least one concentric socket formation defining an inverted frusto-conical shoulder and an elongated insert having a longitudinal trailing shaft portion receivable in a mouth of the forward-facing central cavity of reduced diameter. The elongated insert includes an expansion portion being defined by at least one ball-shaped segment extending forward from the trailing shaft portion, of which the expansion portion fits into the concentric socket formation.

摘要： The invention provides a long range bullet. The bearing surface of the body of the bullet is provided with one or more annular narrows of which the combined length is at least one third of the length of the bearing surface of the bullet and which depth is between 0.005 mm up to half of the groove depth of a barrel in which the bullet is intended to shoot.

摘要： A projectile, such as a guided mortar projectile, has both a front obturator and an aft obturating device. The aft obturating device is located aft of the front obturator, and serves to trap pressurized gases behind the aft obturating device, so as to provide further propulsion to the projectile with the trapped pressurized gases, even after the front obturator has cleared the muzzle of a launcher. The aft obturating device provides less resistance to movement of pressurized gases across the aft obturating device in the aft direction, than to movement of pressurized gases across the aft obturating device in the forward direction, and may act as a check valve with regard to such gas flows. The aft obturating device may be part of a cap that is coupled to a tail boom of the projectile, and that drops away from the projectile after launch.

摘要： A projectile having a downstream extending surface of revolution which terminates as a blunt base has a plurality of circumferentially spaced apart U-shaped, downstream extending troughs in its surface. Each trough is essentially aligned with the direction of the bulk fluid flow adjacent the surface in the vicinity of the trough, and intersects the blunt base to form a trough outlet therein. The troughs are appropriately spaced apart, sized and configured to flow full over their entire length and to cause fluid to flow into the space immediately behind the blunt base, thereby reducing base drag on the projectile.

摘要： An anti-aircraft projectile for intercepting flying objects, such as aircraft and missiles, includes three independent zones which can be coupled to one another and which respectively form a base, a high-explosive body and an ogive. The base includes a bourrelet and has a recess which forms a skirt provided with bypass holes. The high-explosive body is formed by a pair of concentric cylinders wherebetween there is formed a chamber in which are disposed steel balls or spheres which fill the chamber. Both cylinders are coupled at the corresponding ends thereof to both the base and the ogive.

摘要： An aerodynamically stable projectile comprising a substantially cylindrical main body portion and a boattailed base portion having a rear face of substantially equilateral polygonal configuration, with three or more inwardly slanted surfaces. The slanted surfaces may be contiguous or non-contiguous; when they are non-contiguous, the non-slanted tail portions of the projectile form fin-like shapes.
