  • Material options: Aluminum 6061 plate (0.125" or 0.25" thick)
  • Attachment methods: Epoxy, possible fiberglass reinforcement
  • Performance criteria: Maximize downforce, minimize drag, optimize weight

Planning Your Approach

Before diving into Solidworks, conduct thorough research on aerodynamic principles relevant to racecar design. Understand how wing shapes, angles, and materials impact performance metrics like downforce and drag. Familiarize yourself with previous designs and case studies to glean insights into effective design strategies. Once you have a solid theoretical foundation, outline clear design parameters based on project requirements and constraints using Solidworks. Define the 2D wing sections and 3D support structures within the specified dimensions. This initial setup will guide your modeling and simulation efforts, ensuring your designs are both innovative and technically sound.
