Abstract
CANDIDATE MATERIALS AND PROCESSES COMPATIBLE WITH RADIATIVELY COOLED THRUSTERS UTILIZING HYDROGEN/OXYGEN AND STATE-OF-THE-ART OXIDIZING PROPELLANTS AT TEMPERATURES OF ATLEAST 2480 DEGREES K AND ABLE TO WITHSTAND AT LEAST 1000 TEMPERATURE CYCLES ARE SEVERLY LIMITED. NO SINGLE MATERIAL EXISTS TODAY WHICH CAN RELIABLY MEET THESE REQUIREMENTS. ULTRAMET PROPOSES AN INNOVATIVE APPLICATION OF CHEMICAL VAPOR DEPOSITION OF A COMBINATION OF MATERIALS, SPECIFICALLYRHENIUM FOR STRENGTH AND IRIDIUM FOR OXIDATION/CORROSION RESISTANCE TOGETHER WITH A NOVEL FABRICATION TECHNIQUE WHICH WILL ASSURE RELIABILITY. IN PHASE I, ULTRAMET PROPOSES TO DETERMINE THE TEMPERATURE AND LIFE LIMITS AND DEMONSTRATE FEASIBILITY OF THE FABRICATION TECHNIQUE WITH THE END PRODUCT BEING A TESTABLE THRUSTER.
