Abstract: A method for varying the flight path of a missile, in particular of a spin-stabilized projectile, which has an outer wall and which is provided with at least one impulse device. The impulse device can be activated deliberately at a defined time during the flight of the missile. The impulse device is arranged with respect to the longitudinal axis of the missile such that, when it is activated, it generates an impulse that initiates a tumbling movement which causes the flight-path of the missile to be shortened or varied. A spin-stabilized projectile is provided with such an impulse device and it is configured so that the impulse device may be triggered during flight so as to initiate the flight-altering tumbling movement.

Abstract: A weapon barrel of an automatic firearm is subject to bending oscillations during firing.

Abstract: The functionally critical series connection of high-voltage-resistant resistors (Rn, R?n) in a Marx generator (11) is replaced according to the invention by a molding (12, 12?) composed of conductive plastic, which, depending on the configuration grouping of the capacitor bank (Cn), runs over the geometric series of capacitor connections (An, A?n) resulting from this and is connected to them, for example by riveting or screwing (13), in which case it is also possible to use more than one continuous molding, instead of a single molding.

Abstract: A prismatic joint for an optical swiveling device has a first prism which is mounted such that it can rotate about a first rotation axis and a second prism, which is mounted such that it rotate about a second rotation axis with respect to the first prism. The first rotation axis and the second rotation axis intersect one another at an intersection angle of 45°. The first prism and the second prism have a respective first side surface and a second side surface, as well as a base surface. The first side surface is inclined through the intersection angle with respect to the base surface, and the second side surface is inclined through half the intersection angle with respect to the base surface. A third prism has side surfaces that are inclined symmetrically at the intersection angle with respect to the base surface.

Abstract: An optical swiveling device is specified for imaging and/or projection of an object scene, having a supporting structure, having a detection/transmission unit arranged in the supporting structure, having a pitch frame and having a roll frame, with the pitch frame being mounted in the roll frame such that it can rotate about a pitch axis and with the roll frame being mounted in the supporting structure such that it can rotate about a roll axis. In this case the pitch axis and the roll axis intersect at an intersection angle of less than 90°. First deflection optics are arranged in the pitch frame such that a beam propagating along the pitch axis is deflected in an object-side direction which intersects the pitch axis at the intersection angle, and vice versa, and second deflection optics are arranged in the roll frame such that a beam propagating along the pitch axis is deflected in the direction along the roll axis, and vice versa.

A flying object, such as a guided missile, has a number of such folding wing assemblies.

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: A microwave generator having a central electrode (14) which at the front end has a radiating element (22) and an external electrode (18) which coaxially surrounds the central electrode (14) along an axially extending resonator portion (16), wherein the two electrodes (14 and 18) are of a rotationally symmetrical configuration and define a spark gap (62) which sparks across when a high voltage is applied and radiates microwaves by way of the resonator portion (16) and the radiating element (22) of the central electrode (14). The spark gap (62) is in the form of an annular spark gap, which is determined by a connection element (26) which projects at the rear end axially centrally away from the central electrode (14) and an annular edge (44) of the external electrode (18), the edge being provided coaxially with respect to the connection element (26). The central electrode (14) and the external electrode (18) are arranged in a housing sleeve (12) of an electrically insulating material.

The tail portion (24) is connected to the seeking fused munition (10) along a peripherally extending specified rupture portion (26).

Abstract: The production and emission of high-energy microwave pulses are made possible by means of a device with a particularly compact design if the capacitor column (12-12) of the Marx generator (11) whose series circuit conventionally itself feeds a microwave generator with a matched antenna geometry, is now itself used—dispensing with the microwave generator and its antenna—directly as a resonator and Hertzian antenna dipole (24). Its oscillation response can be optimized by triggered spark gaps (14) for the switching of capacitors (12), and by means of plates (19) connected at the ends, in order to increase the stray capacitances.

Abstract: A detector, in particular an IR detector in the seeker head of a guided missile, is cooled with expanding gas generated by depressurizing a pressurized fluid. A mixture which forms a positive azeotrope, including argon or nitrogen as a main component and at least one alkane as a secondary component, is expanded as the fluid. The composition is preferably in the region of a eutectic mixture in order to avoid a component freezing adjacent to the expansion nozzle. This makes it possible to considerably extend the life of the cooler in comparison to that when using pure cooling gases such as nitrogen or argon, and to cool the detector down more quickly, subject to the same constraints.
