Experimental Study of the Effect of Using a Gothic Vortex Generator Counter Rotating Arrangement on Wing Airfoil Eppler 562 with a Smoke Generator

Abstract

The development of science and technology affects all sectors of life, one of them is technological progress in the aviation world. The wing is the most important part of an aircraft because the wing produces an elevator When moving against the airflow because of its airfoil shape. The airfoils found on the aircraft have a pressure difference between the upper surface and the lower surface which causes the aircraft to get lifted. To improve the performance of the airfoil, the wing is added to the wing of the generator vortex. The method used in this study used a wind tunnel. By using smoke in the wind tunnel and fan acceleration against smoke. As well as changing some angles and distances of the gothic vortex generator (VG). Using Eppler 562 with a freestream velocity has a speed of 5 m/s and an angle of attack α = 0°, 4°, 10°, 16°, 20°, and variations in the spacing between gothic vortex generators (VG). The result obtained from this study is the appearance of airflow performance around the airfoil. This is because there is a difference between airfoils that use a gothic vortex generator and do not use a gothic vortex generator. Airfoils that use gothic vortex generators have simpler partition points than airfoils that do not use gothic vortex generators.
