Patent number: 11236980Abstract: A holding device and method for decreasing the contact-impact event on sub-projectiles when fired from a barrel, cylinder, carrier shell or the like includes a core and at least two legs that at least partially enclose at least one sub-projectile each. When a projectile is fired from a barrel or the like the sub-projectiles load the legs of the device which are deformed and open up and release the sub-projectiles in a controlled manner without tumbling which leads them to hit and penetrate their target with the short-side. A holding device including sub-projectiles and a projectile including the holding device are also provided.Type: GrantFiled: September 26, 2018Date of Patent: February 1, 2022Assignee: BAE SYSTEMS BOFORS ABInventors: Christer Thuman, Ulf Heiche, Reijo Vesa

Patent number: 11015907Abstract: A method for modifying a separable projectile between a test embodiment or an effect embodiment includes detaching the front projectile body from the rear projectile body, arranging a payload container in the front projectile body where the payload container comprises measuring equipment or an effect part, and fitting the front projectile body to the rear projectile body by way of a belt. A separable projectile which can be modified between a test embodiment and an effect embodiment is also provided.Type: GrantFiled: September 14, 2017Date of Patent: May 25, 2021Assignee: BAE SYSTEMS BOFORS ABInventor: Ulf Heiche

Patent number: 10502538Abstract: The invention relates to method for pre fragmentation of a warhead (1) comprising a warhead body (2), an explosive charge (6), a fin part (3), and a warhead shell (4) with the density ?shell wherein the warhead shell (4) comprises pre formed cavities (5), where each cavity (5) comprises at least one pre formed projectile (7) with the density ?proj and filler material or agent (8) with the density ?fill, wherein the method comprises the following steps: —pre formation of the cavities (5) in the warhead shell (4), —arrangement of at least one projectile (7) in each pre formed cavities (5), —filling of filler material or agent (8) in the cavities (5) so that the cavities (5) are filled, —treatment of the filler material or agent (8) so that the filler material or agent (8) forms a connected structure vid high adhesiveness to the projectiles (7) and to the walls of the cavity (5). The invention further relates to a pre fragmented warhead.Type: GrantFiled: April 26, 2017Date of Patent: December 10, 2019Assignee: BAE SYSTEMS BOFORS ABInventors: Christer Thuman, Abraham Langlet, Ulf Heiche

Patent number: 8097838Abstract: The invention relates to a method for increasing the range of shells (1, 8, 13) charged with an explosive substance and other types of shell, which function as carriers of the one or other type of active payload. The method according to the invention thus provides an opportunity for increasing the range of fire of most types of artillery piece by increasing the muzzle velocity and the gliding flight capability of shells or projectiles fired from them, but without the need to increase the energy content in the propellant charges utilized for firing the shells or the projectiles concerned. The novelty proposed in accordance with the invention instead represents a radical modification to the design of the shell (1, 8, 13) utilized in conjunction therewith. The invention also relates to a shell charged with an explosive substance or provided with some other active payload which has been given a long range.Type: GrantFiled: September 14, 2006Date of Patent: January 17, 2012Assignee: BAE Systems Bofors ABInventors: Torsten Rönn, Thomas Pettersson, Ulf Heiche

Publication number: 20090145323Abstract: The present invention relates to a method in firing artillery projectiles, such as various types of shells (1, 26), from rifled barrels (5a, 5b) for preventing the degree of wear of the barrel from which the projectiles are fired from having a negative effect on the muzzle velocity of the projectiles. The invention also encompasses a number of artillery projectiles or shells (1, 26) designed according to said method, and a method of manufacturing these. The invention encompasses a number of different variants for solving the stated problem, the basic principle of all of these variants being to adjust the band positions of the shells to the degree of barrel wear, so that a perfect propellant gas obturation is at all times obtained between the band (9, 11-14, 19-21, 23 and 33) and the origin of the rifling in the barrel, regardless of the degree of barrel wear.Type: ApplicationFiled: February 19, 2007Publication date: June 11, 2009Applicant: BAE SYSTEMS BOFORS ABInventors: Lennart Gustavsson, Ulf Heiche, Torsten Ronn

Patent number: 7032521Abstract: A selectable mode multi-mode missile carrying submunitions and incorporating guidance and target seeking functions includes triggering or actuation of the submunitions by programming function on the ground or on board another weapon platform or via a link from the ground or said the weapon platform. The submunitions may also be actuated by an impact function. The programming function incorporates or interacts with mode determining or setting devices that cause the missile and its submunitions to selectively operate either in a penetrator mode, a distributed penetrator mode, or in a separation mode. The submunitions are actuated independently, in sequence, or in common with each other depending upon the operating mode selected.Type: GrantFiled: June 21, 2001Date of Patent: April 25, 2006Assignee: BAE Systems Bofors ABInventors: Torsten Ronn, Ulf Heiche

Publication number: 20040139877Abstract: A cargo device (1) carrying submunitions and incorporating guidance and target seeking functions. The triggering or actuation of the submunitions is determinable by means of a programming function on the ground or on board another weapon platform or via a link from the ground or said weapon platform. The submunitions are also actuatable by impact function. The programming function incorporates or interacts with mode determining devices that cause the cargo device and its submunitions to operate either in a penetrator mode, in which the submunitions are essnetially conjoined in a common griggering or actuation function, or in a separation mode, in which the submunitions sequentially leave the cargo device and thereby function with individual triggering or actuation functions that are independent from, or co-ordinated with, the triggering or actuation functions of the other submunitions.Type: ApplicationFiled: August 20, 2003Publication date: July 22, 2004Inventors: Torsten Ronn, Ulf Heiche
