摘要:
A sabot projectile including a sabot, a subcaliber projectile and a hood arranged in front of the sabot and surrounding at least a part of the projectile. The hood is coupled to the sabot and/or the projectile and is separable therefrom. The sabot is provided with at least one bore extending in the longitudinal direction and arranged for exposure to propellant gases upon firing of the sabot projectile from the barrel of a weapon and for directing the propellant gases onto the hood for accelerating the hood relative to the projectile while the sabot projectile is within the barrel of the weapon.

A flash guide tube arrangement utilized primarily in propellant charge igniters for large-caliber ammunition with laterally located openings from which the ignition gases, emitted by conventional ignition systems, exit, either for the ignition of an ignition booster charge or for the direct ignition of a propellant charge. Indentations emanate axially from these openings and extend into the interior of the flash guide tube, the depth of the individual indentations decreasing in the direction toward the rear end of the flash guide tube. The indentations are preferably radially arranged and several of such radially disposed indentations can be provided in the flash guide tube. The rear end of the flash guide tube can furthermore be constructed as a cone having its apex pointing toward the ignition system.
摘要:
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.
摘要:
A pyromechanical disconnecting device that includes a housing having a receiving space for an ignition element and a supporting floor. A disconnecting tool is disposed in the housing and movable along a path toward a disconnecting point of a current conductor rail. Also disposed in the housing is an ignition element adapted to propel the disconnecting tool along the path to sever the current conductor rail. The ignition element includes an end having a conical flank facing the supporting floor of the housing. An elastic sealing element is arranged about the conical flank and the supporting floor to act as an axial tolerance compensator between the ignition element and the supporting floor of the housing.

A pyromechanical battery pole disconnect element, includes a housing (1) in which an electrical conductor is located, a pyrotechnic active element (14) including a breaking piston with a disconnect element (7) to sever the electrical conductor at an isolating point (11), and a pyrotechnic charge to drive the disconnect element (7). All of the current-conducting components except the active element (14) are combined to form a one-piece battery terminal clamp element (5).

The invention relates to a method for producing a cartridge consisting of a case and a projectile, characterized in that, once the cartridge is fully manufactured, a capillary active, acrylate-based adhesive sealing agent is applied in a controlled manner to the gap arising in the inner mouth of the case when the projectile is inserted therein, in a sufficient quantity as to guarantee full sealing of said gap.

A gas generator, particularly for an airbag, is characterized in that the gas-producing material (6) is arranged in a hermetically sealed charge container (9) and that a flame guide tube (10) is arranged in the charge container (9), which flame guide tube is formed in one piece with the charge container (9) and has only one flame outlet aperture (11).
摘要:
A method for unlocking a window pane secured by a fastening element to a frame element of a window frame, with an inflatable pressure tube being located between the window pane and the frame element, said tube, upon being inflated, forcing the window pane out of the frame element. For reliable and improved element unlocking of the window pane, the pressure tube is inflated by actuation of at least one pyrotechnic gas generator connected to the pressure tube.
摘要:
A gas-producing material for a gas generator, particularly for a belt tightener or for an inflatable impact cushion (airbag) to protect motor vehicle occupants, containing a liquefied gas mixture in which the liquefied gas components consist of a mixture of one or more ethers, olefins, ammonia or hydrogen and nitrous oxide (N.sub.2 O).
