IGF::OT::IGF ORBITEC PROPOSES TO DEVELOP AND DEMONSTRATE THE INNOVATIVE ACOUSTIC RESONANCE REACTION CONTROL THRUSTER (ARCTIC) TO PROVIDE RAPID AND RELIABLE IN-SPACE IMPULSE WITHOUT THE USE OF TOXIC HYPERGOLS, DELICATE CATALYST BEDS, OR CUMBERSOME SPARK SYSTEMS. THE ARCTIC THRUSTER WILL EXCEED CURRENT RELIABILITY STANDARDS, REDUCE RCS COMPLEXITY, AND PROVIDE SYSTEM-LEVEL BENEFITS BY MINIMIZING WEIGHT, DECREASING POWER REQUIREMENTS, AND IMPROVING SERVICEABILITY. THE PHASE I WORK WILL FOCUS ON THE DEVELOPMENT AND TESTING, BOTH AT SEA LEVEL AND VACUUM CONDITIONS, OF A PROTOTYPE ARCTIC THRUSTER, AS WELL AS THE DESIGN OF FLIGHT-WEIGHT ARCTIC THRUSTER FOR PHASE II IMPLEMENTATION.
