Automatic Control for Stabilization and Aerodynamic Design of the Gliding Disk

Abstract

This undergraduate thesis serves as an endeavor to change the game of Ultimate Frisbee through a two-step process. Through mathematical analysis of disk design, manufactured prototypes, and gathered data by way of a wind tunnel, the thesis explores different airfoil profiles and defining characteristics, such as trip wires and edge profiles, that impact lift and drag, as well as separation effects. In addition to the physical profile of the disk, a series of feedback controllers are designed and implemented to remove secondary and tertiary perturbations - undesirable for every frisbee player. The combined result provides recommended areas for improvement in design and a controller that remedies the faults in the disk’s own flight before the players’ eyes.
