ABSTRACT:
A quiet nacelle system for jet aircraft engines includes an elongated nose cowl and nose dome of the nacelle and a sound-attenuating liner applied to the nose cowl, nose dome and fan duct components. 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.
