Long Life Additive Manufacturing Assembly (LLAMA)

Completed NASA Game Changing Development project led by Marshall Space Flight Center with Glenn Research Center support that matured additively manufactured liquid-rocket lander hardware. LLAMA integrated a laser-powder-bed-fused GRCop-42 copper-alloy thrust chamber with directed-energy-deposited and composite nozzles, validating throttling, stability, interfaces, restarts, and high-duty-cycle operation through 51 starts and 994 seconds of hot-fire testing.
