Paper Abstract

This paper presents results from an exploratory research effort involving active control of rotor noise using blade airfoil shape changes. Using a numerical technique for solving the unsteady transonic full potential flow equation, the rotor blade flow problem is considered to study the effect of blade airfoil shape changes on the mach number distribution over the surface of the blade. In particular, the magnitude and location of maximum shape changes required to eliminate shock waves present on the blade (and hence the associated noise) are identified.
