摘要： A gas turbine engine nozzle includes outer and inner bands. Each of the bands includes segments circumferentially adjoining at corresponding splits. The splits of the inner band are circumferentially spaced from the splits of the outer band. A plurality of vanes are fixedly joined to the outer and inner segments which collectively define an accordion loadpath therethrough.

摘要： A process for manufacturing a component in which residual tensile stresses are present in the component surface as a result of the operation by which the surface was produced. The process generally entails removing residual tensile stresses and inducing compressive stresses in the surface of a component by controlled impacting of the surface with two or more jets of fluid. An additional benefit of this invention is that damaged surface regions of the component can be removed simultaneously with residual tensile stresses by abrading the damaged surface region with a jet of abrasive fluid. The fluid jet employed to abrade the component surface is preferably at a pressure of at least 1360 bar, while the fluid jet employed to induce compressive stresses in the component surface is preferably at a pressure of at least 1700 bar. The second fluid jet can be operated to remove any embedded abrasive grit remaining from the first fluid jet operation.

摘要： An electromagnetic peening apparatus includes a first electromagnetic coil having a first face configured to conform to a first surface of a workpiece, and a second electromagnetic coil having a second face configured to conform to a second surface of the workpiece. A carriage positions the first and second coils in abutting contact with the workpiece at respective first and second faces and surfaces. A power supply powers the coils to produce electromagnetic force therein to plastically deform the workpiece at the first and second surfaces to effect a compressive layer therein.

摘要： A free flow abrasive hole polishing system and method improves air flow and resultant component cooling efficiency for an apertured article. The free flow abrasive hole polishing system mixes an abrasive particle component with a carrier media to create a free flowing abrasive particle carrier media mixture. This mixture is pumped through apertures defined by aperture walls in the article to improve air flow and resultant cooling efficiency of the article. Since the abrasive particles have mass and velocity and the free flowing media does not have resistance to flow, the abrasive particles impinge on peaks of the aperture walls, predominantly removing high spots in the aperture walls.

摘要翻译： 自由流动研磨孔抛光系统和方法改善了多孔制品的空气流动和所得到的部件冷却效率。 自由流动研磨孔抛光系统将磨料颗粒组分与载体介质混合以产生自由流动的磨料颗粒载体介质混合物。 该混合物被泵送通过制品中的孔壁限定的孔，以改善制品的空气流和合成的冷却效率。 由于磨料颗粒具有质量和速度，并且自由流动的介质不具有流动阻力，所以磨料颗粒撞击孔壁的顶点，主要消除孔壁中的高点。
