Abstract:
The design configuration of turbofan powerplant installations for commercial aircraft is significantly influenced by the requirement for reduced aircraft noise. This paper describes the design evolution of the installation of the CF6, the high-bypass ratio engine in the McDonnell Douglas DC-10, as it was influenced by the need for noise suppression measures. The candidate alternatives and the basic trade-off criteria leading to the selected configuration are presented.

This paper also includes some considerations associated with choice of material, construction, and design techniques applicable to various areas of sound treatment within the nacelle.
