A numerical study on the design of new generation main and tail rotors blade airfoils has been undertaken to develop advanced rotors for helicopters. Design criteria and objectives for the root and tip main rotor blade airfoils are discussed based on the mission requirements and today's state of the art. The tail rotor airfoil design was aimed specifically to obtain Cmax in the Mach number range up to 0.5 higher than conventional airfoils. Aerodynamic inverse, optimization and analysis methods used in the design process are described. The subsonic and transonic code (MSES) based on the Euler equations and the boundary layer with simulation of the separation effects was extensively used in the design procedure to satisfy the design criteria and to achieve the design goals. The - aerodynamic characteristics of the designed main rotor blade with 12%, 9% and 8% thickness are compared to the third generation advanced rotor blade airfoil family VR12-VR14 of Boeing. This comparison shows the benefits of the new airfoils. Presented effort led to a new tail rotor section design that offered a 38%-48% increase in Cimax in the Mach number range of 0.4-0.5.
