CASELESS PROJECTILE AND LAUNCHING SYSTEM

摘要

A launcher system (2) includes a launcher (5) having a barrel (32, 332, 332', 332", 332'", 332"", 332"'") adapted to receive a projectile (50, 50') and a charge (60, 60') of propellant and a velocity variator configured to shift relative to barrel (32, 332, 332') to selectively vary a launch velocity of projectile (50, 50') from launcher (5). The velocity variator may be constituted by a collar (334, 334') selectively controlling the propellant gases vented out of projectile (50, 50') and into barrel (32, 332, 332', 332", 332'", 332"", 332'"") and/or a sliding breech face (510) behind which is an energy-absorbing plug (540).
