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
