    • A rotor containment structure for gas turbine engine comprises an inner containment layer having a single integral body defining an annular structure about the rotor, and having a support on the inner surface of the inner containment layer for at least one shroud segment. An outer containment layer provides containment strength to contain blade fragments and defining an annular structure about the inner containment layer. Air passage through the outer containment layer for air to pass from an exterior of the outer containment layer to an interior of the outer containment layer; and the inner containment layer being connected at a first end to the outer containment layer with a gap defined between the inner surface of the outer containment layer and the outer surface of the inner containment layer, the gap being in fluid communication with the air passage such that air flows through the gap, beyond a free second end of the inner containment layer.
    • 用于燃气涡轮发动机的转子容纳结构包括内部容纳层,其具有围绕转子限定环形结构的单个整体,并且在内部容纳层的内表面上具有用于至少一个护罩段的支撑。 外部容纳层提供容纳强度以包含叶片碎片并围绕内部容纳层限定环形结构。 通过外部容纳层的空气通过空气从外部容纳层的外部通过到外部容纳层的内部; 并且所述内部容纳层在第一端部连接到所述外部容纳层,所述间隙限定在所述外部容纳层的内表面和所述内部容纳层的外表面之间,所述间隙与所述空气通路流体连通, 空气流过间隙,超过内部容纳层的自由的第二端。
