abstract

The results of a recently completed study on the potential noise-reduction benefits that could be derived from the development of an “Advanced Acoustic-Composite Nacelle” for future subsonic commercial transports are discussed. In this study, noise-reduction objectives were based on the acceptance of noise floors imposed by airframe noise during approach operation and jet noise during takeoff. The reduction of treatable source levels to these floors should result in aircraft noise levels below those of the already quiet current widebodied transports. It is predicted that the foregoing noise levels can be achieved in future widebodied transports by employing advanced acoustical duct liners, extending the (lined) fan duct, and incorporating jet mixing.
