    摘要: A composite gun barrel 10 with active cooling having a breech end and a dharge end. The barrel includes an outer jacket 11 having radially inwardly projecting ports 15 proximate the breech end 25 extending inwardly from the outer diameter of the jacket, and an inner liner 13 inside the jacket and extending beyond the discharge end of the jacket prestressed by autofrettage to form a permanent integral assembly. The inner liner has a circumferentially located annular space 17, the ports being in operable communication with the annular space. A plurality of circumferentially spaced longitudinal channels 19 on the liner extend from the annular space to a location 21 beyond the discharge end of the jacket. The liner includes a shoulder 23 located between the breech end of the barrel and the inwardly projecting ports for locating the jacket on the liner. The liner includes an outer terminal liner portion 27 on the breech end extending beyond the jacket to permit the liner to be held in position for insertion into the jacket, the outer terminal liner portion being removable to form a desired barrel length during finishing of the barrel. Similarly, the jacket includes an outer terminal jacket portion 29 on the breech end extending partially between the outer terminal liner portion and the desired barrel length, the outer terminal barrel portion also being removable to form the desired barrel length during finishing of the barrel.

    摘要: An obturator for guarding the primary sealing surfaces of a step wedge brhblock gun from post-firing residue buildup assures greater survivability of the obturator without the necessity of cleaning after each firing. The device includes an active tube insert for facilitating face seal force multiplication, out of bore lip and face seals, an inbore piston polymer with expanding residue guard, and an out of bore face seal with a residue-tolerant polymer.
