    Abstract: A method for producing porous propellant charges from a mixture containing a propellant and a filler is described wherein a propellant having a decomposition temperature above 200.degree. C. is employed with a thermally removable filler to provide the charge forming mixture. The mixture is molded into a charge body and is subsequently heated to remove the filler at a temperature that is at least 50.degree. C. below the decomposition temperature of the propellant. Due to the heating at the elevated temperature the filler is wholly or in part removed to form a cavity within the charge body.

    Abstract: An electrically primable igniter charge yield has a composition that yields a reduced proportion of toxic vapors after the deflagration. The composition of the charges contains, as the oxidizing agent, zinc peroxide and, as a component providing additional energy, initiating explosives of the kind which do not trigger a detonation in direct contact with press-molded elements of nitrocellulose propellant charge powders. Among these initiating exposives are the potassium salts of trinitrophenol or trinitroresorcinol. The components of the igniter charges are mixed with fibers of an electrically conductive material. Suitable conductive materials are carbon or metals, such as iron or copper, or metal alloys, such as brass, for example. The igniter charges furthermore contain a binder which is preferably a secondary explosive, such as, for example, nitrocellulose.

    Abstract: A short range trajectory round having an aerodynamic resistance which sharply increases at a predetermined time after discharge of the round from a barrel of a weapon. The round includes a body having a longitudinal axis and a forward tip portion and a rear base portion with at least one segment forming a part of the body and arranged for outward movement away from the longitudinal axis. The at least one segment at least partially delimits an inner cavity within the body terminating at a predetermined distance from the tip portion, and a plunger having a forward portion and a rearward portion is disposed within the cavity and arranged for movement in the longitudinal direction of the round between at least a rearward position and a forward position. the plunger is movable to the forward position in response to the firing of the round for form-lockingly engaging the at least one segment to prevent movement of the at least one segment away from the longitudinal axis of the round thereby to establish a first aerodynamic resistance for the round. The plunger is also movable toward the rearward position after discharge of the round from the barrel of the weapon for disengaging the at least one segment to enable outward movement of the at least one segment with respect to the longitudinal axis of the round and thereby establish at least a second aerodynamic resistance for the round which is greater than the first aerodynamic resistance.

    Abstract: An igniter unit for igniting of propellant charges comprises an igniter element operatively associated with a booster charge. The igniter element is arranged within an external housing and the booster charge is provided in an internal housing arranged within the external housing. The internal housing has a closed, lateral wall and a closed base at one end which withstands the ignition pressure generated upon ignition of the igniter element and the booster charge. The internal housing is provided with means for defining openings for causing the cloud of gas produced by ignition to flow from the booster charge and the igniter element to one end, that is the front end, of the internal housing to effect the ignition of the propellant charge.

    Abstract: An after-firing safety mechanism of a training ammunition that is fired through the central barrel of a full-caliber dummy projectile is described. The training ammunition includes a primer igniting an active charge upon impingement of the training ammunition on the target, as well as a locking pin ejectable perpendicularly to the axis of the training ammunition, this pin fixing the primer in place at least as long as the training ammunition is within the barrel of the dummy projectile. The locking pin is inserted in this arrangement in a cavity, to be ejectable by gas pressure. The cavity is in communication with a pyrotechnical gas generator; the latter being connected to an ignition system operating with delay. This ignition system is initiated upon firing of the training ammunition from the barrel of the dummy projectile.

    Abstract: A fastening element having a cavity containing an explosive charge arranged so that, upon explosion of the explosive charge, anchoring of the fastening element in a bore of a workpiece takes place automatically. This fastening element functions both as a rivet and nail in combination and comprises sleeve means defining the cavity containing the explosive charge at one end and providing an aperture at the other end, and a nail disposed within the sleeve means, said nail comprising a head, shank and a tip and being arranged to be driven outside the aperture formed in the other end of the sleeve means. The head of the nail acts as a piston which can be driven by explosion of the explosive charge and as a stop which arrests the driving-out movement when the shank of the nail has passed through said aperture.

    Abstract: This invention deals with case-less ammunition, the propelling element of which has increased solidity. This increase in solidity is achieved by virtue of the fact that the propelling charge is firmly enveloped in a fabric. The fabric may consist of completely synthetic organic fibers or of mineral bibers. The ammunition in accordance with the invention manifests increased stability during loading and transportation in the weapon and better internal ballistics data than comparable ammunition known to date on the basis of the higher tamping attained.

    Abstract: Ignition of a separating charge in a cavity between a flash-conducting tube and a casing of a propellant charge igniter extending below a combustible tube is brought about by the propellant gases passing through priming bores from the outside of the propellant charge igniter to be used in a breech of a cannon or like weapon. This requires a seal acting in the manner of a valve being positioned at the flash-conducting tube head and being urged towards the casing. An especially suitable sealing means in a sealing ring located in an annular groove having a cross-section shape similar to a trapezoid. In case, for example, on account of low temperatures, the pressure buildup of the propellant gases occurs more gradually, the separation of the combustible tube from the bottom piece is thereby also automatically initiated at a later point in time. Thereby, flashback in the breech zone of the cannon is avoided and ballistics are improved.
