Abstract Scope |
High temperature refractory metals are required for higher temperature propulsion applications. Additive manufacture (AM) is under development to produce Niobium (Nb), Molybdenum (Mo), Tungsten (W), and Rhenium based components such as thruster reaction chambers, thermal stand-offs, nozzle extensions, wing leading edges, etc. The most mature of these metals is Nb-based alloy C103. This presentation focuses on component level test under relevant prototypic environments of additive manufactured Nb-based alloy C103 nozzle extensions for rotating detonation rocket engines (RDREs). The effects of hot-fire tests on the material macro- and micro-structure will be discussed. |
