LAUNCH PACK

摘要

Launch pack (5) for accelerating projectiles (4) to hypervelocities in an electromagnetic accelerator (1), comprising a casing (7) in which at least one electric sliding contact (6) is arranged, which sliding contact (6) is formed by multiple fibres of an electrically conducting material onto which an electrically insulating material has been applied, the fibres running from the top to the bottom of the casing (7), wherein the length of the fibres is essentially greater than the height of the casing (7) to such an extent that a feed mechanism is provided to compensate for wearing away of the ends of the fibres.
