    摘要： From a plurality of sabots, a sabot is provided for shrouding a sub-caliber projectile to form a launch package in a gun bore for acceleration by an actuator behind the projectile. The sabot includes a forecastle, an aft bulkhead and a waist. The forecastle separates the projectile from the gun bore. The aft bulkhead abuts against the actuator. The waist connects the forecastle and the bulkhead by a radial spar that supports inner and outer flanges. The inner flange mechanically engages the projectile, and in preferred embodiments is concave. The gun bore is optimized as a pair of electromagnetic rails.

    摘要： To reduce the mass of a sabot having a pull and a push function, it is proposed that the sabot comprise mutually separate sabot parts, wherein at least one sabot part is configured such that it performs the pull function and at least one sabot part is configured such that it performs the push function. The sabot parts are nested. This can be implemented in the form of cylindrical nesting or in the form of tangential nesting. In the case of the cylindrical nesting, the outer sabot part encloses the inner sabot part along an interface. In the case of the tangential nesting, the sabot parts are divided into sabot subsegments. The latter are nested in alternating fashion in the tangential direction such that a pull-sabot subsegment and a push-sabot subsegment are nested in alternating fashion in the circumferential direction. To provide sufficient sealing, the sabot subsegments overlap one another.

    摘要： A telescoped type ammunition including a case inside which is housed a sub-calibre projectile equipped with a segmented discarding sabot, a propellant charge and an igniting device for the propellant charge, wherein the sub-calibre projectile incorporates a prolonged part receiving a tail fin able to move between a folded position against the prolonged part and a deployed position, the sabot retaining the tail fin in the folded position, the sabot encloses the tail fin to isolate it so as to prevent any contact between the tail fin and the propellant charge.

    摘要： A projectile system has a projectile with a metal body having a first outside diameter, a forward end and a rearward end, a plastic base wad engaged at the rearward end, the plastic base wad of solid plastic having a first length and a second outside diameter, greater than the first outside diameter, and a rifled barrel having a third inside diameter at the tips of the rifling, the third inside diameter greater than the first outside diameter but less than the second outside diameter, and a fourth diameter at the root of the rifling greater than the second outside diameter. With the projectile translating along the rifled barrel, the metal body passes inside the rifling, avoiding metal to metal friction, while the plastic base wad fully engages the rifling, imparting rotation to the metal projectile.

    摘要： A fin-stabilized sub-caliber projectile adapted to be fired from a rifled barrel, the projectile having a penetrator with a tail fin assembly, a sabot arranged on the penetrator and having at least two sabot segments circumferentially joined to one another that are separated from one another after leaving the barrel by centrifugal forces acting on the projectile during firing. The sabot includes a main body and a front guide flange that is adapted to be supported on an inner wall of the barrel and a rear guide flange arranged at an axial distance. A connecting section of the sabot is arranged between the front guide flange and the rear guide flange and has a smaller outer diameter than the front guide flange or the rear guide flange. The sabot and the penetrator are joined together in a positive manner in a region of the rear guide flange.
