Experimental study of optimized beginner-level wingsuit

Abstract

Among extreme sports are wingsuits, which influence the safety and quality of an athlete’s flight through their reliability, ergonomics, and aerodynamics. Aerodynamic efficiency and wing surface reinforcement are due to ridges aligned with flow directions. Wrinkles appeared as a result of these. The created uneven surfaces have a significant effect on the performance, the arrangement and geometric shape of the surface can be useful or destructive in different flight situations. Geometric changes on the surface are one of the passive flow control methods. In this article, the geometric structure of these wavy protrusions and their effects on the flight performance of the wingsuit has been investigated. Flow structure is shown using the tuft flow visualization method, which shows the effects of geometric changes on the model in flight angles of attack (AOAs). The wingsuit model was also tested under different AOAs, and the best performance was achieved at AOA = 10° with seven wave ridges arranged on it. Based on the results of this study, we have evaluated the effect of the AOA, the side angle, and the Reynolds number (Re) on the performance of the model.
