Abstract
R&D ON A NVOEL ELECTRIC THRUSTER CONCEPT IS PROPOSED. THE BASIC CONCEPT OF THIS THRUSTER IS THAT THRUST IS PRODUCED BY THE EXPANSION OF HOT PLASMA IN A PAIR OF MAGNET NOZZLES. UPSTREAM CONTAINMENT OF THE PLASMA IS ACHIEVED BY A STABLE MAGNETIC CONTAINMENT SYSTEM. PLASMA HEATING IS ACCOMPLISHED BY A DC DISCHARGE BETWEEN THE TWO ANODES LOCATED INSIDE THE MAGNETIC NOZZLE COILS AND A DOWNSTREAM HOLLOW CATHODE WHICH IS LOCATED ON A MAGNETIC FIELD LINE THAT PASSES NEAR THE CENTER LINE OF THE ANODES. MOST OF THE PROPELLANT IS INJECTED INTO THE DISCHARGE THROUGH THE ANODES. THIS THRUSTER CONCEPT BUILDS DIRECTLY ON BOTH THE BEST OF THE MAGNETOPLASMADYNAMIC (MPD) THRUSTER AND EXISTING STELLARATOR TECHNOLOGY. PRIOR WORK HAS SHOWN THAT THIS TYPE THRUSTER HAS THE POTENTIAL OF ACHIEVING THRUST EFFICIENCIES APPROACHING 80% IN THE SPECIFIC IMPULSE RANGE OF 20003000 SECONDS, I.E. 50-100% HIGHER EFFICIENCY THAN ANY EXISTING PLASMA THRUSTERS. IN THE PROPOSED EFFORT AN OPTIMIZED ENGINEERING DESIGN OF A KW DC THRUSTER AND THE REQUIRED EQUIPMENT AND INSTRUMENTATION TO TEST AND UNDERSTAND IT'S PERFORMANCE WILL BE DEVELOPED. IN PHASE II, THE THRUSTER WOULD BE FABRICATED AND TESTED.
