Mar 1, 2025March 2025 for PURPL-Purdue/Turbopump: Implemented Gas Generator Injector CAD and manufacturing data updates, consolidating seven commits into a single user-facing improvement. This included updates to CAD models (GasGeneratorInjector_02-27.SLDPRT), injector subassembly refinements, an injector overhaul, and system-wide data alignment. Created translation logs for STEP to UG and synchronized binary part files to reflect manufacturing data, enabling smoother production handoffs and reducing downstream rework. No major bugs fixed this month; actions focused on data integrity, design accuracy, and cross-tool interoperability. Business impact includes improved design accuracy, faster production readiness, and stronger traceability of CAD assets. Technologies demonstrated: CAD/PLM workflows, STEP-to-UG translation, binary data handling, and version-controlled design updates.
