ABSTRACT	High performance/low noise airfoils of a helicopter rotor have been proposed based on a new concept. Those new airfoils were designed for the blade tip section (8% thickness ratio) and for the blade root section (10% thickness ratio). In this study, the aerodynamic performance was set to be higher than Clmax, Mdd and L/D of existing airfoils. To verify the aerodynamic performance of the new airfoils, wind tunnel tests were conducted in the two-dimensional transonic wind tunnel at NAL.
