Spin Compensation for Shaped Charge Liners

The U.S. Army has a requirement for a shaped charge warhead that can maintain its penetration capability while spinning. The current solution, a linear fluted liner, is optimal over a narrow band of spin rates compared to the span of rates experienced by a typical spin-stabilized munition over its effective range. To increase performance on target, a solution that is effective over a larger range is desired. The goal of this effort is to evaluate the performance of multiple spin compensation methods and determine the optimal parameters for each concept to mitigate the penetration reduction due to angular momentum over a broad range of spin rates. Concepts that broaden the effective range over which the spin compensation of the munition is effective will be pursued to further maximize their performance. Corvid will achieve this through a high fidelity computational physics led design and optimization process exploring a number of spin compensation concepts/techniques. Top performing concepts will be down-selected for prototype fabrication and testing in Phase II to support implementation into a tactical configuration.
