A report discusses the design and testing of a laboratory-model arc-jet thruster designed to operate at a nominal power level of 300 W. This thruster is an intermediate product of continuing efforts to develop smaller, lower-power, higher-specific-impulse thrusters for use in a forthcoming generation of small communication and scientific satellites. The thruster features a modular design, with a nozzle geometry chosen to promote supersonic-arc attachment.

This work was done by John M. Sankovic of Lewis Research Center and David T. Jacobson of Ohio State University.
