Abstract : An analytical investigation has been initiated to define the lift coefficient - Mach number characteristics of airfoils of potential interest for helicopter application. Then, this analysis was extended to determine the relative importance of the airfoil geometric parameters such as thickness, thickness distribution, leading-edge radius, camber, and camber distribution on lift-Mach number characteristics.
