Investigation of The Effects of Twist Angle On Wing Performance and Stall Characteristics In Low-Speed Wings

Abstract

One of the most notable features expected from the wings used in airplanes is that they allow an economical flight. In addition, wings must contribute to the provision of a safe flight in terms of their structural features. Therefore, studies on improving the performance of wings are increasing day by day. In these studies, performance analysis is carried out by changing the incidence angle from the root to the tip without changing the airfoil structure of the wing. However, it has been observed that the effect of the twist angle on the performance and flow separations of the wings used in low-speed aircraft has not been sufficiently examined or the research have not been compiled in a regular format. It is known that changing the angle of incidence along the wing, that is, twist of the wing, increases the lift stability along the wing and improves the stall characteristics of the wing. In this review, for the reasons, it is aimed to investigate the effects of twist angle on wing performance, flow separation and stall characteristics of wings used in low-speed aircraft.
