Vortex Ring Generator: Mechanical Engineering Design for 100-kpsi Operating Pressures

Abstract

This report documents engineering design guidelines used to construct an explosive gas generator (100 kpsi maximum) and an adjustable area ratio (2844 maximum) nozzle. The equipment enables ring vortices to be generated using jet streams with significantly higher Mach numbers than previously reported in the literature. Studies are planned of the risks, limits, and capabilities of ring vortices for nonlethal crowd control applications. The focus is limited to 40-mm weapons, so this report is written to facilitate technology transfer to investigators interested in other applications and launch platforms.
