    • A gas turbine engine combustor liner with improved high temperature capability is achieved by embedding ceramic tiles into a fiber reinforced glass ceramic matrix composite substrate, so as to incorporate a space between the tiles and the substrate, the space serving to eliminate a direct heat conductive path between the tile and the substrate. The space is created by inserting a fugitive layer between the tiles and the substrate prior to compaction of the substrate, followed by removal of the fugitive layer. A fugitive material sprayed on the supportive region of the tiles prior to liner fabrication prevents the substrate material from bonding to the tiles, and prevents cracking of the tiles during temperature cycling.
    • 具有改善的高温能力的燃气涡轮发动机燃烧器衬套通过将陶瓷砖嵌入到纤维增强玻璃陶瓷基质复合衬底中来实现,以便在瓷砖和衬底之间形成空间,用于消除直接导热路径 在瓦片和基底之间。 该空间是通过在压片之前在瓦片和基底之间插入一个短暂的层,然后移除该分散层来产生的。 在衬垫制造之前喷洒在瓷砖的支撑区域上的短效材料防止衬底材料粘结到瓷砖,并且防止瓷砖在温度循环期间的破裂。

    • A combustor shield assembly is provided wherein a plurality of ceramic tiles are mounted on a ceramic support panel, which panel has a plurality of keyhole-shaped apertures therethrough to receive a plurality of ceramic tiles, each of which has a knob upstanding on a neck from the base or shield of such tile, each of the knobs being sized to fit through the larger end of the apertures, but not the smaller end thereof to provide a bearing and support surface for such knob and thus for the tiles. An apertured retaining panel is provided, having apertures slightly larger than the knobs, which panel is positioned over the top of the support panel with the apertures thereof around the respective knobs to secure the tiles in place in the support panel. A plurality of the so-assembled tiles on their respective support panel are mounted in spaced overlapping layers to a combustor liner so as to mount the tiles before the liner as a heat shield therefor. In addition air inlet passages are provided between each such tile assembly so that cooling air can be input between the above tile assembly layers to further cool and protect the combustor liner in concert with such tile assemblies. In a preferred embodiment, an insulating layer or blanket is positioned on the back side of each tile around its support knob, between tile and support panel to further insulate such panel and provide a cushion for the brittle ceramic tiles.
    • 提供了一种燃烧器屏蔽组件,其中多个瓷砖安装在陶瓷支撑板上,该板具有穿过其中的多个键孔形状的孔,以容纳多个陶瓷砖,每个瓷砖具有在颈部上直立的旋钮 这种瓦片的基部或屏蔽件,每个纽扣的尺寸适合穿过孔的较大端部,但不限于其较小的端部,以提供用于这种旋钮并因此用于瓦片的轴承和支撑表面。 提供有孔保持面板,其具有稍微大于旋钮的孔,该面板位于支撑面板的顶部上方,其孔围绕相应的旋钮,以将瓦片固定在支撑面板中的适当位置。 在它们各自的支撑面板上的多个如此组装的瓦片以间隔开的重叠层安装到燃烧器衬套上,以将瓦片安装在衬垫之前作为隔热罩。 此外,在每个这样的瓦片组件之间设置空气入口通道,使得冷却空气可以在上述瓦片组件层之间输入,以进一步冷却并保护燃烧器衬套与这种瓦片组件一致。 在优选实施例中,绝缘层或毯被围绕其支撑旋钮,瓦与支撑板之间的每个瓦的背面定位,以进一步绝缘这种面板并提供用于脆性陶瓷瓦的衬垫。
