This project modeled the Supermarine Spitfire’s elliptical wing in Mathematica to analyze its structural response under realistic aerodynamic loading. The simulation incorporated distributed lift, gravitational, and tip vortex loads while using energy methods to determine deflection and strain energy. The model was designed to be fully modular, allowing the number and placement of spars to be adjusted to evaluate their effect on overall structural stiffness and stability. This configurability enabled comparative studies between single-, dual-, and multi-spar wing configurations to assess structural efficiency.
