A Study of The Relationships Between Pressure and Deformation of Surface on Wingsuit Performance

Wingsuit as one of the most popular sports in the field of aviation is very popular. Efficiency and safety are the first priority of the designers of this sport. In this article, the modeling, formation, and evaluation of the surface of the wingsuit during a flight are discussed. Since the wingsuit is under air pressure inside it, the formation of the structure of the surface of the suit changes according to the flight conditions. The surface of the wingsuit is important for the aerodynamic evaluation of the wingsuit model. According to the way of sewing wingsuit clothes, the wave structure will be obtained on the surface of the wing. In order to better observe the effects of changing the wing geometry on maneuverability, the model has been selected as rigid. The experimental results on the surface of the model show that with the increase of the angle of attack, the flow on the surface of the wing increases the disturbance in the middle area of the wing and reduces its effects in the upper area of the wing. This interaction of the flow structure on the model leads to the different performances of the model in different angles of attack; By measuring the forces on the model, AOA= 15 was obtained as the best angle of flight performance for the wingsuit model.
