Abstract: The invention relates to a film-type ignition element, used in particular for igniting the propellant charge of large-caliber ammunition. The invention furthermore relates to a method for producing an ignition element of this type.

Abstract: In cannon ammunition including a cartridge case containing a propellant charge, a case bottom to which the cartridge case is connected, a charge igniter, and a primmer element positioned in the case bottom, the improvement in which the cartridge case is combustible, is connected to the primer element, and includes a combustible material and a pyrotechnical mixture which is embedded within the combustible material and which is composed of at least one reducing agent and at least one oxidizing agent which form a pyrotechnical redox system; and the charge igniter consists of the cartridge case.

Abstract: A charge arrangement for cartridge ammunition having a cartridge case, a bottom igniter secured in the case bottom and a primer that coaxially surrounds at least one part of the propellant composed of bulk powder and a tail-side part of a projectile that projects into the cartridge case. To ensure reliable ignition of the propellant bulk in a simple manner, a primer is provided that is comprised of either a separate, relatively thin-walled, combustible sleeve or the inner layer of a multilayer, combustible cartridge case which faces the propellant.

Abstract: A method and an apparatus for producing a large-caliber ammunition unit including a combustible or partially combustible propelling charge casing and compacted or partially compacted propelling charge powder, to increase internal ballistic performance. It is known to partially or completely compact or compress the propelling charge powder in a cartridge casing. However, such methods generally cannot be employed for ammunition including a combustible or at least partially combustible propelling charge casing because of the lower strength of the relatively thin-walled combustible casing material, as this would lead to deformation and/or to reduced loadability of such cartridges.

Abstract: A performance enhanced ammunition unit composed of a front ammunition component (1) and a rear ammunition component (2) which each include a combustible propelling charge casing (7, 12), with the rear ammunition component being filled with propelling charge powder that has been compressed into a compressed member (15). The rear ammunition component (2) has a casing bottom (13) which accommodates a bottom igniter (14) and the compressed member (15) accommodates a combustible ignition tube (16) for the propelling charge igniter (16, 17), with the combustible tube 16 being in operative engagement with the bottom igniter (14) and extending along substantially the entire axis of the bottom component. Both ammunition components (1, 2) are separated by a combustible disk (18), the front ammunition member (1) is filled in its cylindrical section (8) filled with powder rods (10) and in its section (a) ahead of the powder rods with bulk propelling charge powder (11).

Abstract: A modular propellant charge (10) composed of N propellant charge modules (1; 11-16) each having a length Lo. In order to obtain an economical, durable, easily released connection between the propellant charge modules (1; 11-16), a displaceable sleeve (6; 17-22) of a length L is axially slidably arranged on the exterior of each propellant charge module (1; 11-16) with the relationship ##EQU1## applying for the length L. The displaceable sleeves are utilized to interconnect adjacent modules.

Abstract: To improve the combustion behavior of a two-part large-caliber ammunition round (10) composed of a primary charge (20) and a projectile charge (30), an annular transfer charge (29) is provided in the primary charge (20) underneath a charge casing cover (28) which terminated the primary charge toward the top. The projectile charge (30) is also provided with an annular transfer charge (39) above its propelling charge casing bottom (38). The transfer charge (29) disposed in the primary charge (20) results in rapid destruction of the charge casing cover (28) and of the casing bottom (38). The annular transfer charge (39) disposed in the projectile charge (30) improves the ignition of the tubular propellant (32) disposed in the projectile charge (30) and of the loose powder charge (36) without noticeable time delays relative to the primary charge (20).

Abstract: A receptacle for the propelling charge for large caliber gun ammunition is combustible, and includes a barrel-protection coating which is applied directly to the interior surface of the receptacle. The coating is composed of a mixture of wax and titanium dioxide. In order to prevent the propelling charge powder in the receptacle from directly contacting the coating, the coating is covered with a thin metal foil, such as a thin lead foil.

Abstract: An ignition transfer body for a propellant-charge module is coaxially surrounded by a supporting tube and includes at least one clear ignition channel. The ignition transfer charge is composed of a first propellant-charge powder generating thermal energy in a range of 3 kJ/g to 4.5 kJ/g, and the supporting tube is composed of a second propellant-charge powder. Preferably, the second propellant-charge powder forming the supporting tube is pressed powder which is extruded or pressed in a mold.
