Experimental program for investigation of high power density MHD

Research on magnetohydrodynamic (MHD) power generation, directed at the proof-of-concept of combustion MHD as a viable source for use with space-based weapons systems, is described. Currently, small-scale laboratory evaluations of a solid-aluminum, carbon-fueled hybrid combustor are being completed. Ultimate plans for this research include coupling of this combustor to an MHD generator to demonstrate high power density in the laboratory. This report includes experimental results from the initial hybrid combustor tests. The design of this combustor system and its design point are detailed. Experimental data from firings are presented and analyzed. The burn or regression rate for this fuel is summarized. The combustor tests have been successful; the design point for this system was readily achieved and sustained
