| Abstract Scope |
Relativity Space is developing a medium-to-heavy lift launch vehicle that leverages laser powder bed fusion (PBF) of copper and nickel-based alloys for the majority of engine components. Rapid implementation of performance- and productivity-driven process changes necessitates a material qualification approach that is both adaptable and comprehensive. This work presents an approach to material qualification and the development of design properties and allowables within a production environment that includes multiple printer OEMs and in-process changes targeted at performance and manufacturing efficiency. The qualification strategy employs conservatively based data analysis methods to enable manufacturing flexibility while maintaining reproducibility and compliance. This approach supports initial vehicle block production, while future vehicle iterations will transition to an evolved qualification framework designed to enable enhanced re-use and material performance. |
