Projectile acceleration system using heated barrel and expanding propellant
A recently granted patent (Publication Number: US11920888B2) discloses an innovative apparatus designed for propelling projectiles through a barrel using compressed light gas. The apparatus comprises a barrel with controllable heaters, a first chamber for positioning the projectile, and a second chamber for directing pressurized light gas behind the projectile for acceleration through the bore. The apparatus also includes valves for controlling the flow of purge gas and a shear plate to prevent gas flow between chambers.
Furthermore, the patent details a method for operating the apparatus, involving heating the bore surface, placing the projectile in the first chamber, adding light gas to the second chamber, purging the first chamber with a purge gas, compressing the light gas, and ultimately propelling the projectile through the bore. The method emphasizes the use of specific gases such as hydrogen, helium, neon, or argon for optimal performance, along with heating the bore surface to temperatures exceeding 700° K. Additionally, the compression of the light gas can be achieved through the movement of a piston using a railgun armature or by creating an electrical arc in the second chamber. These innovative features highlight the potential for enhanced projectile propulsion efficiency and control in various applications.
