Develops and implements performance requirements and design criteria for evaluating propulsion test facilities including cryogenic and high-pressure propellant systems.
Conducts preliminary investigations to obtain baseline data for propulsion test system studies. Documents design process (i.e. design reviews) per procedures.
Develops, exercises, and reviews mechanical mathematical models (flexibility, structural) of test facility pressurant, purge, and propellant systems in support of rocket propulsion test activities.
Generates Piping and Instrumentation Diagrams (PIDs), 3D models of pipe routes/structural elements within existing facility models, and fabrication drawings.
Provides technical consultation to civil servants and supports contractors in the resolution and correction of field problems. Monitors corrective actions through completion.
Applies theories, principles, practical concepts, and recommends new processes related to engineering design and its standards, codes, techniques, and practices for process piping.
Fosters a culture of engagement, diversity, inclusiveness, excellence and innovation. Champion NASA's commitment to Diversity, Equity, Inclusion and Accessibility to create an environment that promotes a commitment to safety, integrity, and teamwork.
