Self-adjusting obturator for projectile launching |
摘要 |
Propellant pressure forces generated within the bore of a gun barrel are applied to a projectile through a self-adjusting obturator to prevent projectile blow by of propellant explosion products. The propellant forces are transmitted through a body of shock-absorbing fluid in the obturator protectively isolated from surfaces of the barrel and projectile by a non-porous, flexible enclosure wall deformed into sliding contact with the barrel bore during projectile launch for preventing propellant pressure loss.
