Patent number: 8607704Abstract: The invention relates to a method of, in the electrical ignition of a propellent charge (1) provided with an electrically conductive surface coating (5) and comprising one or more propellant components (3), ensuring that ignition and progressive combustion of the propellent charge take place. The method is characterized in that said electrically conductive surface coating, when ignition of the propellent charge is desired, is connected to an electrical high-voltage source (6), in that said high-voltage source is made to generate at least one high electrical pulse to said connected electrically conductive surface coating, and in that said at least one high electrical pulse produces an instantaneous flashover ignition of the electrically conductive surface coating of the propellent charge and of all its propellant components, simultaneously. The invention also relates to a propellent charge and to an ammunition shot comprising the propellent charge.Type: GrantFiled: March 23, 2009Date of Patent: December 17, 2013Assignee: BAE Systems Bofors ABInventors: Ola Stark, Lennart Gustavsson, Johan Dahlberg, Lars-Peter Svanberg

Patent number: 8544387Abstract: 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 are at least two radially perforated propellant tubes, which are arranged in their entirety inside or after one another, and which have at an e-dimension selected in relation to the actual type of propellant and its desired combustion characteristic, combustion or ignition channels, and which have circular outer and inner boundary surfaces, in conjunction 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 intended to delay the propagation of ignition to that surface so that the combustion of the propellant tubes is partially mutually overlapping.Type: GrantFiled: April 4, 2011Date of Patent: October 1, 2013Assignee: Eurenco Bofors ABInventor: Johan Dahlberg

Patent number: 7921777Abstract: 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.Type: GrantFiled: December 8, 2004Date of Patent: April 12, 2011Assignee: Eurenco Bofors ABInventor: Johan Dahlberg

Publication number: 20090148549Abstract: 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.Type: ApplicationFiled: February 12, 2009Publication date: June 11, 2009Applicant: Eurenco Bofors ABInventors: Johan Dahlberg, Lennart Selin
