Cold-Formed Tungsten-Copper Hybrid Sub-Projectiles for Maximum EMRG Effectiveness(1001-353)

Triton Systems Inc. proposes to fabricate low drag, high stability aerodynamic sub-projectiles by a cold forming approach in which a dense and hard Tungsten rod is surrounded by a shaped sleeve of another metal. Detailed design tradeoffs will be completed to evaluate the appropriate proportions of the two materials and the optimal shapes for minimizing sub-projectile energy loss in its terminal trajectory. Several candidate sub-projectiles will be fabricated during the Phase I, using prototype tooling. These will be fired on an instrumented test range to obtain estimates of Ballistic Coefficient and aerodynamic stability, validating computerized trajectory simulations. Triton will be assisted in the Phase I effort by Kline Engineering of Newton NJ and Draper Laboratory of Cambridge MA. Kline Engineering personnel will provide aerodynamic design support and trajectory simulations. Draper will provide carrier projectile integration support and overall system effectiveness background. During the Option Phase , a second iteration of sub-projectile design, prototype manufacturing and testing will occur. The Phase II effort will include adapting and optimizing the most promising sub-projectile designs and tooling up for production in the 1000s of parts per month.
