초록

In a jet engine in which the engine cowling includes an inlet cowl and an engine containment case and in which at least a portion of the interior surface of the inlet cowl is covered by an acoustic treatment material, a system for attaching the inlet cowl to the engine containment case icludes an attachment ring that is substantially U-shaped in cross section having a web and first and second legs extending orthogonally from the web. The first leg abuts an engine flange that is a part of the engine containment case. The first leg and engine flange are se...
