Advanced Modular Gun Design

NAVSEA DAHLGREN

Applied Ordnance Technology (AOT) has developed a high velocity, high pressure, large caliber test gun that incorporates a separable chamber using AOT’s extended Long Range(XLR) gun design. AOT’s objective is to provide the Navy with the Advanced Modular Gun Demonstrator, a test and evaluation gun based on the XLR design, that is capable of testing advanced gun technologies. The XLR gun was developed in conjunction with Advanced Power Technology, Inc., and offers an innovative approach to loading, chamber sealing, chamber/barrel connection and recoil. The design consists of a high-velocity, smoothbore gun incorporating multiple separable large-volume chambers and a segmented barrel. The key innovation involves the use of a separable chamber bridged by a single-use chambrage sealing cartridge in a high pressure, large caliber gun. The development of the XLR Gun recently advanced with the successful evaluation of the chambrage sealing cartridge in a sub-scale Proof of Concept test at a 60,000 psi chamber pressure. AOT is currently working on a full-scale, full pressure test to evaluate the separable chamber in a relevant gun environment.

Applications

  • Military and Commercial Significance:
  • DoD gun & gun subsystem evaluation (i.e., advanced projectiles, barrel wear/erosion, materials, propellants, etc.)
  • Aerospace (NASA) - hypervelocity testing
  • Aerospace (Boeing, Lockheed, Pratt & Whitney)- scramjet testing
  • Gun (launcher) design enabling industry to launch full caliber projectiles at high speeds
  • DoD programs often require a gun system capable of firing projectiles at ever-increasing velocities and ranges. The versatility of the XLR test gun provides a means to evaluate many different gun subsystems, which helps to facilitate greater advancements in gun technology.
