We are finished conducting data trials and have cleaned up and returned all supplies. The above video is of a trial conducted with our largest dimple size. You can only see the car moving backwards (for filming clarity reasons) but it starts with the wind tunnel being turned on and the Lab Quest being started. We will narrate and explain this with supplementary pictures in the presentation so that there is no confusion. Trials went pretty well overall. We got data, but it was extremely varied. It is hard to tell whether or not dimples affect the drag force on a car without proper statistical analysis. We had some issues with the car not pulling back, but we were able to get 30 samples per dimple type to satisfy the CLT. I would say that trials were successful, even if we cannot determine results without formal analysis.
