Abstract: A panel for lining a gas turbine engine fan casing includes a honeycomb core sandwiched between a backing skin and an outer skin. The backing skin is attached to an inner surface of the casing such that the outer skin forms a radially inward facing surface of a fan duct of the engine. The panel is joined along its sides to similar neighbouring panels such that, in use, the joined panels form a row of panels along the inner surface of the casing. The outer skin or the backing skin includes two face sheets bonded on top of each other, which are arranged such that their edges along each panel side that joins to a neighbouring panel are staggered in the direction of the row. The interfaces between the abutting face sheet edges are therefore correspondingly staggered in the direction of the row.

Abstract translation: 用于衬套燃气涡轮发动机风扇壳体的面板包括夹在背衬皮肤和外皮之间的蜂窝芯。 背衬皮肤附接到壳体的内表面，使得外皮形成发动机的风扇通道的径向向内的表面。 面板沿其侧面连接到类似的相邻面板，使得在使用中，接合的面板沿壳体的内表面形成一排面板。 外皮或背部皮肤包括彼此顶部粘合的两个面片，它们布置成使得它们沿着连接到相邻面板的每个面板侧的边缘在排的方向上交错。 因此，邻接的面片边缘之间的界面因此在行的方向上相应地交错。
