This paper presents a summary of NASA's propeller and rotor noise research. The objective of this research is to develop the technology and data base required to reduce propeller and rotor noise with minimum performance penalties. The status of current research will be described for both low- and high-speed propellers and for helicopter rotors. Recent results and future research thrusts are also discussed
