If the work proposed herein is successful, AFR/DOD would have two new next generation Firesets capable of significantly advancing the testing capabilities of current Firesets to support future hydrocode simulation/modeling of insensitive initiators/EFIs. The two Fireset Systems to be delivered as a result of the proposed Phase II SBIR would first include a refined System 1 design within the first 6 months of the program based on an optimized version of the PoC device developed under the Phase I effort, The second Fireset which would be the major focus of the Phase II effort would be one based on the System 2 Specifications. AFRL needs these two next generation HV Fireset systems which will be capable of much faster rise-times, less shot-to-shot timing jitter, higher peak currents, and more energetics variability & control to support future hydrocode simulation/modeling efforts. The proposed project would develop an optimized 30-60kV Fireset with significantly more energy than the Phase I PoC system, with greater than 100kJ of stored energy and peak currents exceeding 1MA. At the very least the outcome of this program will allow the DoD to perform more accurate experimentation related to advanced detonation transfer studies of novel fuze technologies.
