This paper aims to explain two drone projects that introduce students to Computer-Aided Design (CAD), design, analysis, and simulation through several project-based learning modules. In any Unmanned Aerial Vehicle (UAV) configuration, the airframe is one of the principal components of the whole structure that can be used as a design topic. So, students develop CAD models of airframes and used SolidWorks simulation software, to perform Finite Element (FE) analysis studies. The drone frame was simulated and analyzed in various conditions such as drop tests, during takeoff, and in-flight maneuvers. FE Analysis showed whether components of the airframe will break, fail, or properly work in desired operations.
