Developed the Wing_Box_Detailed Structural Analysis Toolkit for the sofia-ys/Aircraft-Design repository, delivering a foundational module for early-stage aircraft structural validation. The work centered on implementing Python-based functions to calculate tensile stress and assess safety margins for wing-box components, supporting more informed design decisions. Integrated basic data visualization using matplotlib to present safety margin results, enabling rapid feedback during design iterations. The toolkit’s modular structure lays the groundwork for future automation and expanded analysis capabilities. Demonstrated skills in structural analysis, numerical computation, and data visualization, providing essential tools that streamline the validation process and facilitate future enhancements within the project.
