PROFILE
Charliecharliez
Charlie Zhu contributed to the PURPL-Purdue/Turbopump repository by developing and refining CAD assemblies for turbopump inlet and sealing systems, focusing on both RP1 and LOX interfaces. He applied 3D modeling and mechanical engineering principles to deliver parameterized features, such as O-ring grooves, and standardized part naming for improved traceability. Using STEP and binary formats, Charlie enhanced data organization, integrated ANSYS simulation workflows through named selections, and updated rotor assembly measurements to increase simulation fidelity. His work emphasized robust file management, assembly organization, and documentation, resulting in streamlined CAD-to-manufacturing handoffs and reduced integration risk across evolving hardware configurations.
