In this current world of technology, airfoil has been produced for concave wing in many different shapes in terms of root size, tip, existence of winglet and different thickness.Concave wing isthe tendency of a wing to bend during flying at a certain height of deflection. Itincreased higher velocity of the aircraft,mainly due to the increase of lift force produced above the wing.However bySolidWorks,airfoil design for concave wing with NACA 2412 has been choosen.In this study, 0.2m deflection shows the highest lift coefficient andlift drag ratio compared to other height of deflection.The maximum value of CLobtained is 1.517, while for CL/CDis 37.708. This indicates that the airfoil can produce high lift even at low angle of attack, which is beneficial when aircraft wants to take-off, climbing and landing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
