【 摘 要 】

Additive Manufacturing, or 3D printing, is a key technology for enhancing rocket engine designs and making them more affordable for future exploration missions. The Oxidzer Turbopump (OTP) offers the ability to demonstrate additively manufactured rotating, vaned, and critical pressure vessel components in relevant oxygen turbopump environments. The additively manufactured components of the OTP include the main housings, impeller, and turbine components. A key technology development goal is to understand the benefits and limitations of additive manufacturing as it applies to the complex geometries needed for a rocket engine turbopump.
