Abstract: A penetration-capable projectile has a casing and a fuze with a fuze housing lower part. An interface area between the casing of the projectile and the fuze housing lower part is formed with a shape and/or strength modification which prevents the fuze housing lower part from being pushed into the casing on impact with a target that is to be penetrated.

Abstract: A spin-stabilized correctible-trajectory artillery shell has a generator in the rotation-decoupled engagement region between a canard guidance unit and its munition body. The generator can be switched over to avoid load fluctuations between an adjusting motor and a substitute load. In order to avoid an additional heat source in the interior of the guidance unit the substitute load is in the form of an electrical resistance on, at or in canard surfaces behind the afflux flow edges. The canard surfaces are preferably formed on anti-spin canards which are not adjustably mounted.

Abstract: In order to move a textile braking element (16) which is in the form of an annular disk and which is deployed radially under the effect of centrifugal force rapidly into a contour which is stable in respect of shape and which is always properly defined even under afflux flow conditions, a cloth (33) which is cut in the form of a circular ring is provided by virtue of radially extending tucks or darts, with a reduced outside periphery (32) in such a way that the opening movement is thereby limited to the shape of a flat obtuse-angled hollow truncated cone which, by means of reinforcing bands (34) which are sewn on along generatrices of the frustoconical surface, is pivotably mounted to the holding ring (15) at the inside periphery (31) while along the outside periphery (32), it is provided with a peripherally extending accumulation of mass (29) for increasing the centrifugal deployment forces; wherein in the front end region of the stowage space (14), the ring (15) is axially fitted into the contour of the fus

Abstract: A projectile (12) to be fired from a rifled barrel (66) is described. At its tail (10) it has control surface vanes (14) which can be pivoted out from a sub-calibre launch position into an over-calibre functional position. To protect the inwardly folded vanes (14) and to protect further ballistic and sensor structures at the tail end of the projectile (12), a securing pot (18) is temporarily fixed to the tail (10) of the projectile (12), the securing pot having a pot peripheral portion (22) and a pot bottom (24). There is a pressure chamber (32) between the tail end face (26) of the projectile (12) and the pot bottom (24) of the securing pot (18). The pot bottom (24) has at least one propellent gas inlet (34) which opens into the pressure chamber (32). When the projectile (12) is fired from the barrel propellent gas flows through the propellent gas inlet (34) into the pressure chamber (32) so that a correspondingly high propellent gas pressure is produced in the pressure chamber (32).

Abstract: A deformable mirror (10) with an at least quasi-continuously deformable optically effective surface (12) has a floatingly supported mirror plate (11) which is positioned along its edge by a portion of the adjusting members (14.1), whereas the other portion of the adjusting members (14.2) locally individually deforms the mirror plate (11) for the purposes of wave front correction. In that respect all adjusting members (14.1, 14.2) are fixed to the rear side (13) of the mirror plate (11), with a coupling portion (11) which is provided with a desired-flexion location (constriction (25)).

Abstract: In order to provide that the braking elements (16), which are to be deployed radially under the effect of centrifugal force, of the braking arrangement in the region of the ogival head of a spin-stabilized artillery projectile (12) are secured in the rest position and can then be released in a defined manner when reaching the braking point of the ballistic trajectory, the stowage space (14) for accommodating the braking elements (16) is radially covered by a hood (22) which is fitted on to the projectile fuse (11) in the afflux direction and is axially fixed between a recess (24) in the rear wall (25) of the stowage space and a front-end holding ring (26) connected to the ogival head.

Abstract: A spin-stabilised artillery projectile (11) can be easily subsequently fitted with an axially symmetrical aerodynamic braking device for reducing the ballistic trajectory if the tip (14) which is equipped with the fuse (13) and which is easily removable from the projectile body (12) is equipped at approximately half its height with flap-shaped sectors (24) which are pivotably mounted in such a way that they can be pivotably extended and which in their launch position fit snugly into the conical peripheral surface of the tip (14) and in the operative position are pivotably extended to form a radial ring which is closed or which has gaps.

Abstract: In the case of a deformable mirror (11) with a mirror plate (13) which is in glass form in particular for high laser frequencies and an axial actuator (20) which concentrically engages the rear side of the mirror surface (17)—with a reduced actuator stroke movement for the same dome-like configuration height—the dome configuration of the convex curvature of the mirror surface (17) is now of larger area and at the same time better approximated to the desirable sphere if, instead of the central application of force, the arrangement provides for decentral application of force at diametrally opposite locations. For that purpose the actuator (20) operates on a ring (25) which is disposed behind the mirror plate 13 and which is preferably integral with the mirror plate (13).
