Magnetohydrodynamic Augmented Propulsion Experiment

Over the past several years, efforts have been under way to design and develop an operationally flexible research facility for investigating the use of cross-field MHD accelerators as a potential thrust augmentation device for thermal propulsion systems.The baseline configuration for this high-power experimental facility utilizes a 1.5-MW e multi-gas arc-heater as a thermal driver for a 2-MW e MHD accelerator, which resides in a large-bore 2-tesla electromagnet.A preliminary design study using NaK seeded nitrogen as the working fluid led to an externally diagonalized segmented MHD channel configuration based on an expendable heat-sink design concept.The current status report includes a review of engineering/design work and performance optimization analyses and summarizes component hardware fabrication and development efforts, preliminary testing results, and recent progress toward full-up assembly and testing M
