Effect of camber on the flutter characteristics of different selected airfoils

Flutter is the phenomenon where the body will experience uncontrolled motions after reaching a certain velocity known as the critical velocity. The focus of this work is on studying the influence of position of camber of an airfoil on its flutter behaviour. Four different NACA five digit airfoils we...

Description
Summary:Flutter is the phenomenon where the body will experience uncontrolled motions after reaching a certain velocity known as the critical velocity. The focus of this work is on studying the influence of position of camber of an airfoil on its flutter behaviour. Four different NACA five digit airfoils were selected based on the variation in position of camber and were analyzed at different air speeds. These airfoils were studied for their pitch and plunge behaviour which are the base for understanding the flutter characteristics of any body and the flutter characteristics are derived from those results.
