    摘要： A method of making a transparent article includes mixing an oxygen source, a nitrogen source, a magnesium source, a silicon source and a calcium source. The oxygen source, the nitrogen source, the magnesium source, the silicon source, and the calcium source are milled and heated to form a molten oxynitride glass modified by calcium and magnesium. The molten oxynitride glass modified by calcium and magnesium is then cooled to form a transparent body having ballistic resistance with a level of performance satisfying Level IV of National Institute of Justice Standard 0108.01. Transparent articles having transparent bodies formed from the oxynitride glass are also described.

    摘要： An airfoil includes an airfoil body that has a trailing edge region. The trailing edge region includes first and second monolithic ceramic exterior walls, a flow discharge passage between the first and second monolithic ceramic exterior walls, a ceramic matrix composite (CMC) liner at least a portion of which is disposed in the flow discharge passage between the first and second monolithic ceramic exterior walls, and an array of pedestals disposed in the flow discharge passage. Each of the flow guides bridges the CMC liner and at least one of the first and second monolithic ceramic exterior walls.

    摘要： A variable vane system includes an outer platform, an inner casing radially inward from the outer casing and a vane extending between the inner and outer casings defining a vane axis. An inner vane stem is engaged with the inner casing and an outer vane stem is engaged with the outer casing. The system includes a bearing gap defined radially with respect to the vane axis between each of the inner and outer casings and respective vane stems for allowing the vane to rotate about the vane axis for varying angle of attack. The system includes a pressurized air supply inlet in fluid communication with at least one of the bearing gaps to form a stem air bearing to intermittently float at least one of the vane stems for controlled rotation about the vane axis.

    摘要： A variable vane system includes an outer platform defining a centerline axis, an inner platform radially inward from the outer platform with respect to the centerline axis and a vane extending between the inner and outer platforms defining a vane axis. The vane has an inner vane stem and an opposed outer vane stem. The inner vane stem is engaged with the inner platform and the outer vane stem is engaged with the outer platform. The system includes a bearing gap defined radially with respect to the vane axis between each of the inner and outer platforms and respective vane stems for allowing the vane to rotate about the vane axis for varying angle of attack. The system includes a pressurized air supply inlet in fluid communication with at least one of the bearing gaps to form a stem air bearing to intermittently float at least one of the vane stems for controlled rotation about the vane axis.

    摘要翻译： 可变叶片系统包括限定中心线轴线的外平台，相对于中心线轴线从外平台径向向内的内平台以及在限定叶片轴线的内平台和外平台之间延伸的叶片。 叶片具有内叶片杆和相对的外叶片杆。 内叶片杆与内平台接合，外叶片杆与外平台接合。 该系统包括在每个内平台和外平台之间相对于叶片轴线径向限定的轴承间隙和相应的叶片杆，用于允许叶片围绕叶片轴线旋转以改变迎角。 该系统包括与至少一个轴承间隙流体连通的加压空气供应入口，以形成杆空气轴承，以间歇地浮动叶片杆中的至少一个，以围绕叶片轴线受控旋转。
