The key requirements of high energy acoustics within aerial IED detection and neutralization systems are size, weight, high SPL output and a consistent sound source. This SBIR submission addresses these needs and is aimed at providing such sources. The baseline approach for this project is to expand upon the successful design of Wattre Corp.'s HyperPulse device. The HyperPulse is a vortex ring generator designed in 2010-2011for use as a standoff deterrent device. The current generation of this chemical gas-based pulse generator can generate 180dB+ in single-pulse mode and, although not optimized for rapid fire, can reach frequencies up to 9Hz in multi-pulse lower amplitude mode. The proposed device within this SBIR is achieved through modification/reduction in size and power while also increasing frequency. The proposed Phase I and Phase I Option programs will be performed by the Wattre Corp. research staff and its strategic team member and partner USSI. Wattre Corp is well known for their unmatched expertise in the generation of high power in-air acoustic sources while USSI is known for its acoustic signal processing and low cost manufacturing expertise.
Benefit: Proposed research study will further understanding of pulse width modulated combustion and its acoustic opportunities.
