Abstract

This research is a detailed experimental study on aerodynamic characteris-tics for wing model airfoil Eppler 562 with and without wingtip. There are two types of wingtip fences at variations that will be used in this research that are rearward and forward wing tip fence set at cant angle 900. The chord length of the airfoil is 72 mm and the span length is 300 mm. The Reynolds (Re) number used is 2.3 x 104 (U.. = 10 m/s) with angle of attack variations (a) = 0° to19°. For this research, pressure distribu-tions over the airfoil were measured using a pressure transducer. Moreover, measure-ments lift and drag forces of the airfoil were obtained by using a load-cell system. Oil flow visualization method was used to represent the surface flow patterns. The experi-mental results showed that as the angle of attack increased, the separation and the transition points moved towards the leading edge at all models. Furthermore, for airfoil with forward wingtip fence with cant angle 90o CL/CD is better than for airfoil with rearward wingtip fence with cant angle 90o and plain wing. Forward wingtip fence showed the best optimum performance of a = 10o settings compared to the other models.
