摘要： The disclosure relates to a submunition disposed to be separated from an aeronautical body, for example a shell carrier canister or the like above a target area, the submunition essentially including a warhead (5), a target detector (6) and a device which imparts rotation to the submunition for scanning the target area in a helical pattern (4) during the fall of the submunition towards the target area. The target detector (6) is pivotally disposed on a carrying shaft (12a) parallel to the line of symmetry (5a) of the warhead in order to permit outward activation of the target detector (6) from a collapsed position where the optical axis of the target detector coincides with the line of symmetry (5a) of the warhead to an activated position where the optical axis of the target detector is parallel with the line of symmetry (5a) of the warhead, so as to permit free scanning vision for the target detector (6) beyond the warhead (5).

摘要： The invention relates to means for reducing the spread of shots in a weapon system in which the shots are fired from the weapon in a ballistic trajectory from a launching device towards a target. It comprises means for measuring the position of the target, means for measuring the muzzle velocity of the ammunition unit, and, in one embodiment, also means for measuring the actual trajectory parameters of the ammunition unit (shell, projectile or the like), for instance the reduction of velocity in a specific trajectory distance. In response to these values the impact point is predicted. A braking command is transmitted to the ammunition unit via a radio line in response to the difference between the actual position of the target and the predicted impact point for braking the velocity of the ammunition unit in order to improve the hit probability. The braking means preferably comprises a plurality of braking flaps distributed about the periphery of the ammunition unit. Normally the braking flaps are retracted but they can be activated into a protruding position by an actuating device. Alternatively the desired braking effect can be obtained by separating different parts of the nose section from the body of the ammunition unit in order to increase its air-resistance.

摘要： A method and an apparatus for reducing the spread of hit pattern for a rotationally-stabilized ammunition unit such as a projectile, which is discharged in a ballistic trajectory from an artillery piece towards a target which is to be combated including dynamic balancing of the shell (1) to reduce the effect of the air resistance between different shells, and increase hit probability. The inclination between the main axis of inertia of the shell and the geometric axis of the shell case are measured, whereafter these axes are set in parallel in that an adjustment weight (2) is mounted on one side of the point of gravity of the shell seen in its longitudinal direction. The adjustment weight (2) preferably consists of a disk or washer provided with an eccentric recess (4) for suitable weight and mass eccentricity.

摘要： An explosive shell case of the kind in which fragments are produced by bursting of the case material into a number of small particles. The case material comprises a completely dense, non-compressible material which is made with embrittling zones (4) which when the shell bursts gives fragments of a predetermined shape. The case is preferably manufactured powder-metallurgically, the embrittling zones then being formed by filling at predetermined intervals with powder with the embrittling component. The case is then pressed under high all-round pressure and high temperature into a dense, compact jacket and is imparted its final properties through heat treatment.

摘要： A shell case comprising prefabricated fragments (4), preferably of a material with high density, and a supporting material which surrounds the fragments and together with these forms a connected shell which surrounds the explosive of the shell. The supporting material consists of a completely dense non-compressible material which is permanently connected with the pre-fabricated fragments, for instance a hardenable steel. The shell is preferably manufactured by a powder metallurgical procedure in which the supporting material in the form of a metal powder together with the pre-fabricated fragments (4) are pressed under high all-round pressure and high temperature into a dense compact jacket.
