    摘要： The resent invention relates to a method for producing propellant charges with progressive combustion characteristic and a higher charge density than previously considered possible to achieve, intended in the first instance for direct-firing barrel weapons such as tank cannons. Combined in the charge that is characteristic of the invention are at least two radially perforated propellant tubes (10-12, 28-30, 48-52) which are arranged in their entirety inside or after one another, which process, at an e-dimension selected in relation to the actual type of propellant and its desired combustion characteristic, combustion or ignition channels (2, 19-21, 37), and which have circular outer and inner boundary surfaces, in conjuction with which, before initiation of the charge, at least one of the total number of outer surfaces of these propellant tubes that are available for initiation has been treated with an inhibition, surface treatment or surface coating (13-18, 33-36) intended to delay the propagation of ignition to that surface, so that the combustion of the propellant tubes is partially mutually overlaping and taken together, gives rise to a maximum propellant gas pressure behind a projectile fired with the charge from the barrel in question, which pressure, for the entire passage of the projectile through the barrel, lies close to the applicable Pmop value for the barrel ( the maximum operational pressure, i.e. the highest barrel pressure that can be permitted continously).

    摘要： The present invention relates to a method for producing propellant powder charges intended for heavy barrel weapons, such as canons and howitzers, and with a high degree of filling and a high energy content, and also to propellant powder charges produced in accordance with this method. The charges according to the invention are distinguished by the fact that 70 to 95% of their weight consists of a more coarsely grained powder and 30 to 5% consists of a granular powder with a smaller grain size. These two powders have the same of different chemical composition, and one or more of them can be surface-inhibited.

    摘要： The present invention relates to a method and a device for producing perforated propellant in the geometric form of block, stick, slab, cylindrical or tubular propellant (2) with high charge density and high progressivity. The propellant as claimed in the present invention is characterised by a large number of perforations, densely and evenly distributed over the entire propellant segments, made by perforation members (6) that are pressed down into the propellant. The perforations are thereby made in a plurality of steps with a predetermined step feed between each perforation operation. The device as claimed in the present invention also comprises a mobile pin die (5) away from but facing the feed path (1) for the propellant (2), and containing at least one row of pins for perforation of the propellant whereby each such row of pins comprises the number of pins (6) required to cover the complete width of the propellant segment across its direction of advance. Between each perforation operation the propellant is step fed by a step feed device (15) a distance equivalent to the distance between two desired perforations multiplied by the number of rows of pins arranged across the direction of advance of the propellant. Additionally, in the propellant as claimed in the present invention the distance between two burning surfaces of the propellant shall be equal to double the desired burning length (2b).

    摘要： The present invention relates to a method and an arrangement for the production of radially perforated, cylindrical propellant tubes (1, 23, 31). The invention is based on the underlying idea that the respective propellant tube (1, 23, 31) must be fixed and centred between its own open ends and thereafter to be perforated in stages in a large number of consecutive perforation operations by means of one or more pins (13) capable of displacement in a pin die (10) relative to the propellant tube towards and at least through the major proportion of the cylindrical wall of the propellant tube. Also included in the invention is the requirement for the displacement, between each perforation operation, of the propellant tube and the pin die (10) used for the preparation operation in such a way relative to one another that the propellant tube, after a complete perforation operation, shall be covered in its entirely by perforations (32, 33, 35, 36), which lie at a predetermined e-dimension distance from one another.

    摘要： The present invention relates to a method for phlegmatising an explosive (21) in an aqueous suspension (20), containing a dispersion solution (24) and a dispersion decomposer (23). It is characterised in that the phlegmatising agent (25) is deposited on the surface of the explosive (21) at low temperature by means of their opposite electric charges. The invention also relates to a device and an explosive phlegmatised by means of said method and device.
