This SBIR program will develop a lightweight, high performance ceramic matrix composite thruster for DACS propulsion. The Phase I program will identify the sealing and joining materials, and demonstrate the processes that are suited for construction of advanced ceramic matrix composite (CMC) thrusters for advanced monopropellants and bipropellants for DACS propulsion. We will seal CMC surfaces and join CMCs to each other and to refractory metals. We will experimentally evaluate Sienna s ultra-high temperature, oxidation resistant joining compounds through joining experiments, microstructural examination, and shear strength measurements both at room temperature and 1100°C. Simple test thrusters will be fabricated and tested by Aerojet-Sacramento at high temperature and at high pressure at sea-level laboratory tests.
