PROFILE
Andrew Fontanetta
Worked on the PURPL-Purdue/Turbopump repository, delivering core simulation and analysis features for rocket turbopump systems over four months. Developed a physics-informed overhaul of the throat-area calculation to improve simulation fidelity, implemented nozzle sizing tools with updated mass flow constants, and introduced a Pressure Map Module for oxidizer and fuel feed systems. Focused on code refactoring and repository cleanup to enhance maintainability and accelerate design iteration. Leveraged Python, MATLAB, and scientific computing libraries such as matplotlib to support engineering calculations, data analysis, and testing. The work emphasized accuracy, traceability, and robust validation to support reliable turbopump design and review.

Nov 1, 2024Concise monthly summary for 2024-11: Delivered a physics-informed overhaul of the throat-area calculation (A_throat) for PURPL-Purdue/Turbopump, enhancing simulation fidelity and business relevance. The change improves predictions for both cold gas integration and hot-fire turbine paths by refining throat area computation using characteristic velocity and initial pressure, updating constants for initial and exit pressures, and adjusting related parameters such as nozzle count and shaft power. The work was validated through commits that clearly document the improvements and provide traceability.
