  • Test gun barrel extension joint
    Patent number: 11125522
    Abstract: Disclosed herein is a test gun barrel for use with a long range projectile testing system. The test gun barrel comprising a main gun barrel and a gun barrel extension. The main gun barrel and gun barrel extension each include a joint end having aligning cylinders and bores to properly align the main gun barrel to the extension prior to engaging threaded coupling. A seal capable of being inspected is made once main gun barrel is fully coupled to gun barrel extension.
    Type: Grant

  • Method for gun barrel manufacture using tailored autofrettage mandrels
    Patent number: 6810615
    Abstract: A method of manufacturing a monobloc gun barrel by calculating an optimal residual stress profile and then applying tailored autofrettage mandrels which are mechanically pressed down the bore of a large caliber barrel, the mandrel size optimized to create a residual stress distribution on the interior of the bore within the design constraints imposed by the worst-case heat flux scenario.
