Jan 1, 2026January 2026 monthly summary for PURPL-Purdue/Turbopump. Delivered two injector design parameter calculators to accelerate injector optimization and parameterization for RP1/LOX. Implemented: (1) a quadlet manifold parameter calculator focusing on propellant mass flow distribution and injector design optimization, and (2) a triplet injector calculator providing detailed injector parameters (orifice diameter, exit velocity, and pressure drops) for RP1 and LOX. Implemented changes are tracked in two commits: cee5eb88d7358971bab4ad205c97b0d3e60a6354 and ecfba40e90917697541479de237c83f19e5185df (Add files via upload). This work establishes a reusable design automation foundation, enabling faster, data-driven injector studies and design iterations. No major bugs reported; repository state remains stable.
