    • A high temperature gas turbine component for use in the gas flow path (120) that also is a specular optical reflector. A thin layer of a high temperature reflector (116) is applied to the gas flow path of the component, that is, the surface of the component that forms a boundary for hot combustion gases. The component typically includes a thermal barrier coating (114) overlying the high temperature metallic component that permits the component to operate at elevated temperatures. The thermal barrier coating (114) must be polished in order to provide a surface that can suitably reflect the radiation into the gas flow path. A thin layer of the high temperature reflector (116) the is applied over the polished thermal barrier coating (114) by a process that can adequately adhere the reflector to the polished surface without increasing the roughness of the surface. The high temperature reflector (116) can be applied to any surface aft of the compressor, such as on a turbine nozzle. The surface reflects radiation back into the hot gas flow path (120). The reflected radiation is not focused onto any other hardware component. The design of the component is such that the radiation is returned to the gas flow path (120) rather than absorbed into a component wall that only serves to increase the temperature of the wall.
    • 一种用于气流路径(120)中的高温燃气轮机部件,其也是镜面光学反射器。 将高温反射器(116)的薄层施加到部件的气体流动路径,即形成热燃烧气体边界的部件的表面。 组件通常包括覆盖高温金属组件的热障涂层(114),其允许组件在升高的温度下操作。 必须对热障涂层(114)进行抛光,以便提供能够将辐射适当地反映到气体流路中的表面。 将高温反射器(116)的薄层通过能够将反射器充分地粘附到抛光表面而不增加表面粗糙度的工艺施加在抛光的热障涂层(114)上。 高温反射器(116)可以应用于压缩机后面的任何表面,例如在涡轮喷嘴上。 该表面将辐射反射回热气流路(120)。 反射的辐射不集中在任何其他硬件组件上。 部件的设计使得辐射返回到气体流动路径(120),而不是被吸收到仅用于增加壁的温度的部件壁中。

    • A high temperature gas turbine component (104) for use in the gas flow path (120) that also is a specular optical reflector. A thin layer of a high temperature reflector (116) is applied to the flow path surface of the component, that is, the surface of the component that forms a boundary for hot combustion gases.

The thermal barrier coating (114) must be polished in order to provide a surface that can suitably reflect the radiation into the gas flow path.
