A Low Power Pulsed Arcjet Thruster for Spacecraft Propulsion
Abstract
dc:descriptionA pulse-forming electrical circuit is developed to reduce energy losses in the storage capacitor, and greater than 85% of the initial stored energy is transferred to the arc in a unipolar pulse. A high current diode installed across the capacitor terminals is used to eliminate voltage reversals in the current. The experimental breakdown voltage of the helium gas between the electrodes is found to follow a Paschen relationship where the minimum electrode separation distance is used in evaluating the data.
