Abstract Scope |
Space propulsion efficiency is often restricted by physical limitations of the materials for combustion chambers and nozzles. The limitations are consequences of extreme environmental conditions (T-differentials, thermal shock, reactive propellants, etc.), and can manifest as limited burn time and lifetime, fuel constraints, etc. By capitalizing the recent advancements on complex-concentrated-alloys (CCAs) and additive manufacturing (AM) technologies, combined with computational modeling, the concurrent development of improved material and seamless structure can be realized and accelerated, to allow customized systems enabling higher propulsion efficiency. This talk aims to showcase a multiscale materials design framework built to advance the state-of-the-art CCAs and related hybrid solutions towards the practical needs (current and future) of the space propulsion industry. Examples from ongoing development of novel refractory CCAs for in-space bi-propellant thrusters will be provided, where thermal control, mechanical integrity, fuel compatibility and AM processability are key design factors, to ultimately increase thruster burn time. |
