Description
Summary:A review of SIRENS electrothermal launcher research program is presented. SIRENS research program focuses on the understanding of boundary layer physics with typical EM/ET plasma characteristics. Diagnostics development includes in-bore measurements of high heat flux and plasma conductivity. A comparison between the erosion of various material surfaces under typical EM/ET high heat loading conditions is also presented. Fuseless (vacuum) versus fuse (atmospheric) operation showed that barrel pressure may reach 0.75 kbar at an input energy of 5 kJ to the source. Presented at the Electromagnetic Launcher Association Meeting (10th) held in Dayton, OH on 15-17 Sep1992. Sponsored in part by contract DAAA22-91-M-4001.
