GENERALIZED ROTOR PERFORMANCE

Abstract

The report presents a summary of generalized rotor performance charts suitable for preliminary design in the rotary-wing field. Generality is achieved by nondimensional presentation of power requirements over the complete range of rotor lift and propulsive requirements for a wide spectrum of speed conditions. Lines of constant power are shown on a lift-drag coordinate system for each speed condition, providing a useful tool in the development of rotored aircraft configurations. Techniques are presented for employing the charts in a variety of design problems, including the compound helicopter, where the optimum combination of rotors, wings, and auxiliary propulsion devices is desired.
