| 摘要 | A recoilless and detonation-free projectile firing device comprises a tube having a front muzzle end with an inturned flange portion defining a front end stop and a rear end with a cap secured thereto with an inturned flange which defines a rear end stop. The tube contains a cartridge case made of an elastic material of a low modulus of elasticity which has an outer diameter which permits it to be snugly fitted within the interior of the tube. Arranged within the cartridge case from the front muzzle end toward the opposite rear end in order and in ready-touse form are: a muzzle end brake ring adjacent the front stop, a projectile to be fired, a cartridge case base for the projectile, a propellant charge, an opposite cartridge case base having an inert material of easy divisibitlity and a rear end braking ring. All of the elements are combined in the cartridge case and are hermetically sealed therein by diaphragms which are secured to each end of the case. | ||||||
| 权利要求 | 1. A recoilless and detonation-free projectile firing device, comprising a tube having a front muzzle and with a projectile discharge opening and with a front stop adjacent the opening and having a rear opening with a rear stop adjacent the rear opening, a cartridge case in said tube of elastic material of low modulus of elasticity having an outer diameter substantially equal to the interior diameter of said tube, said cartridge case containing projectile firing and detonation and recoil-preventing elements arranged in firing order from the muzzle end to the rear end and comprising a first brake ring in said cartridge case adjacent the projectile discharge opening, a projectile to be fired within said cartridge case adjacent said first brake ring, a first cartridge case base associated with said projectile in said cartridge case, a second cartridge case base in said cartridge case opposite to said first cartridge case, a propellant charge located between said first and second cartridge case bases, inert material adjacent said second cartridge case base on the ends toward said rear opening, and a second brake ring in said cartridge case adjacent said rear openIng, and diaphragm means at each end of said cartridge case hermetically sealing said cartridge case. 2. A recoilless and detonation-free projectile firing device, according to claim 1, wherein said cartridge case has a conically-shaped wall. 3. A recoilless and detonation-free projectile firing device, according to claim 1, including a metal foil vapor lock in said cartridge case. 4. A recoilless and detonation-free projectile device, according to claim 1, including means for ejecting said cartridge case from said tube by the residual pressure developed by ignition of the propellant charge and after the projectile has left the tube. |
