Abstract: The utilization of metal hydride and an acidic reagent for the accelerating of masses, and propulsion devices for applying such materials. The materials are of a saline complex metal hydride and acidic reagent which is sprayed onto the metal hydride which is offered in a lumpy consistency, for the pulse-like generation of expanding reaction gas bubbles in a constructive or dynamically, yieldably dammed chamber. Also provided is a propulsion device for the application of the above materials, with a support for a saline complex metal hydride of a lumpy consistency in a yieldably dammed expansion chamber in which an injection nozzle for the reagent is directed towards a surface portion of the metal hydride.

Abstract: A warhead for a nose-diving aircraft or missile utilized for the attacking of quasi-stationary targets which possess reducing or weakening armour along their vertical height, especially such as radar installations. The warhead has its explosive received within frusto-conically shaped casing region which is constructed as a fragmentation casing, and a cylindrical casing region located in front of the base or tail end, and which is covered with small, radially oriented projectile-forming inserts.

Abstract: A method for effectuating the acceleration of an object, in particular a piercing or penetrator object, within a surrounding liquid medium of a density which is higher than the density of gases, such as in water; as well as an arrangement for producing and imparting an advancing or propelling force to an object in a surrounding liquid medium of a density which is higher than the density of gases; and in particular to an obejct which is to be driven into a water bottom or seabed.

Abstract: An insert for a projectile-forming charge with a non-constant or varying material thickness extending in the centripetal direction thereof. The insert incorporates peripherally mutually offset centripetally extending zones with a material thickness which is constant in the centripetal direction, and which alternates in transition with centripetally extending zones having a non-constant varying material thickness. In the interest of an improved combat effectiveness for large-caliber ammunition, notwithstanding greater target distances, through periodically varying the material thickness of the insert in the peripheral direction, during the folding in of the insert projectile there can be achieved a more stable flight trajectory due to the formation of defined stub wings at the tail end of the projectile.
