Abstract
A quiet nacelle system for jet aircraft engines includes a nose cowl and nose dome having a sound-attenuating liner, a concentric ring between the nose cowl and nose dome, and fan duct components having a sound-attenuating liner. The system is particularly suitable for JT3D-3B and JT3D-7 engines for use with DC-8 aircraft. The components may be combined as a hush kit for retrofit in existing nacelle systems.
