Summary: | An improved Gurney model considering explosive energy waste originated in the process of driving rod-shaped fragment revolving, is proposed herein to predict initial velocity of parallel-moving rod-shaped fragment using parameters such as Gurney constant, mass ratio of explosive charge to rod-shaped fragments, and slanting angle of rod-shaped fragments arrangement. Static arena test was performed to evaluate validity of said improved model, and predictions based on the improved Gurney model exhibit impressive consistency with test results, providing a reliable methodology to predict initial velocity of parallel-moving rod-shaped fragments in the engineering development of controllable discrete rod warhead. |
