    • A wall structure for a gas turbine engine structure, such as a combustion chamber or an afterburner duct is disclosed having a plurality of cooling orifices formed through the wall located in a plurality of odd and even transverse rows, each row having a plurality of cooling orifices located in a plane extending substantially perpendicular to a longitudinal axis of symmetry with the cooling orifices of each odd and even row being circumferentially offset from the cooling orifices of the adjacent upstream corresponding odd and even row. The cooling orifices have a common diameter D and are circumferentially offset a distance d such that distance d is between 0.5 D and D. The axes of the orifices in the odd numbered rows lie on a first main line extending obliquely to the longitudinal axis of symmetry and to the oxidizer air flow, and the axes of orifices on the even numbered rows lie on a second main line, also extending obliquely to the longitudinal axis of symmetry and to the oxidizer air flow. The axes of the orifices in the adjacent rows lie on secondary lines which extend obliquely to the first and second main lines and also to the longitudinal axis of symmetry. Any weld joints necessary to form the annular combustion chamber or afterburner duct from a plurality of wall segments extend parallel to the secondary lines and may be spaced equidistantly from adjacent secondary lines.
    • 公开了一种用于燃气涡轮发动机结构的壁结构,例如燃烧室或后燃器管,其具有多个通过位于多个奇数和均匀横向行中的壁形成的冷却孔,每排具有多个冷却孔 位于基本上垂直于纵向对称轴延伸的平面中,每个奇数和偶数行的冷却孔周向地偏离相邻上游相应的奇数和偶数行的冷却孔。 冷却孔具有共同的直径D,并且在周向上偏离距离d,使得距离d在0.5D和D之间。奇数行中的孔的轴位于相对于纵向对称轴线倾斜延伸的第一主线 和氧化剂空气流,并且偶数行上的孔的轴线位于第二主线上,其也垂直于纵向对称轴线和氧化剂空气流延伸。 相邻行中的孔的轴线位于相对于第一和第二主线倾斜延伸并且还延伸到纵向对称轴线的次级线上。 从多个壁段形成环形燃烧室或后燃器管道所需的任何焊接接头平行于次级管线延伸,并且可以与相邻次级管线等间距地间隔开。

    • Die vorliegende Ertfindung betrifft ein Schleifverfahren für Profilteile, insbesondere Turbinenschaufeln, entsprechend hergestellte Schaufeln sowie typische zugehörige Zwischenpro­dukte. Um die Zahl der Arbeitsgänge bei der Herstellung zu ver­einfachen und eine wirtschaftliche Produktion zu ermöglichen, werden die Konturen von Fuß (2), Kopf (3) und konvexer Saugsei­te (4) einer Turbinenschaufel durch Tiefschleifen in einer Einspannung hergestellt. Ein für diese Bearbeitung geeigneter Rohling weist an seinen Enden Reststücke (8, 9) auf, welche zur Einspannung dienen und später abgeschnitten werden. Durch Rotation und Translation des Rohlings relativ zu einer schnell rotierenden Schleifscheibe wird die gesamte Schaufel­kontur mit Ausnahme der Druckseite hergestellt. Um einen wirt­schaftlichen Schleifvorgang zu gewährleisten, folgt beim Vor­formen das Zerspanungsvolumen pro Zeiteinheit einer vorgeb­baren Funktion, die ggf. auch konstant sein kann. Diese, even­tuell orts- und/oder zeitabhängige Funktion des Zerspanungs­volumens pro Zeiteinheit berücksichtigt zur Vermeidung von ther­mischen Beanspruchungen der Oberflächenschicht die Wärmeabfuhr im Werkstück in der Umgebung der jeweiligen Schleifstelle. Beim Fertigschleifen in der gleichen Einspannung wird schließ­lich die endgültige Kontur und Oberflächenbeschaffenheit er­reicht.
    • 为异型件的磨削方法,特别是涡轮叶片,叶片相应等典型关联的中间产品制造。 为了减少制造过程中的操作的数量和使可能的有效生产,基部(2),头部(3)的轮廓和凸起的吸力侧(4)的涡轮叶片的通过深磨在一个夹紧SET-制造 起来。 一个空白的适合于该加工具有在其端部的剩余件(8,9),其用于夹紧和以后被切断。 与压力侧的例外整个叶片轮廓由旋转和空白相对的平移制造成高速旋转的砂轮。 为了确保在磨削手术高效,金属的每单位去除的时间量期间遵循可预先确定的功能的预成形,因此哪个函数可以是恒定的,如果需要的话。 这可能是依赖于位置的和/或依赖于时间的金属每单位时间除去的体积的函数考虑到在respectivement磨削点附近的工件上的散热,以避免在表面层中的热应力。 最后,最终的轮廓和表面光洁度精磨削在同一夹紧建立期间得到。 ... ...

    • A method for producing a profiled part from a blank, wherein the cross-sectional profile of the part to be produced differs in some portions both quantitatively and qualitatively from the cross-sectional profile of the blank, so that different amounts of material must be removed between a starting profile of the blank and a desired final profile of the part includes pre-shaping and finish-grinding the part to be produced in one chucking position with at least one profiled grinding wheel. The blank is translated and rotated relative to the at least one profiled grinding wheel during the pre-shaping step for giving the blank approximately a desired profile. The finish-grinding step is performed at least partially after the pre-shaping step for smoothing surfaces and producing the final profile to accurate dimensions. A turbomachine blade, an intermediate product for the turbomachine blade and a method of manufacturing the interim product are also provided.
