Lift Augmentation between Passive and Active Vortex Generator

Abstract:

This study was conducted to investigate the performance of passive and active vortex generator on the wing’s flap. The triangular shape of passive vortex generator (VG) was developed and attached on the wing’s flap leading edge while the plasma actuator performed as active vortex generator. The test was carried out experimentally using subsonic wind tunnel with 30⁰ angles extended flap. Three different types of turbulent flow; with Reynolds number 1.5 x10⁵, 2.0 x10⁵, and 2.6x10⁵ were used to study the aerodynamics forces of airfoil with plasma actuator OFF. All Reynolds number used were below 1x10⁶. The result indicated that airfoil with plasma actuator produced higher lift coefficient 12% and lift-to-drag ratio 5% compared to airfoil with passive vortex generator. The overall result showed that airfoil with plasma actuator produced better lift forces compared to passive vortex generator.
