具体实施方式
现在参见附图，图1示出了包括多个压缩机级的燃气涡轮机压缩机2的轴向压缩机流动路径1。压缩机级在图中顺序标记。压缩机流动路径可包括任何数量的转子级和定子级，例如18。然而，转子和定子级的精确数量是工程设计的选择。如本发明所实施的，能够在燃烧室中提供任何数量的转子级和定子级。17个转子级仅是一个示范性的涡轮机设计。18个转子级并不意味以任何方式限制本发明。
压缩机转子叶片将动能传递给空气流且因此获得流经压缩机的所希望的压力上升。紧接在转子翼片后面的是定子翼片级。转子翼片和定子翼片都使得空气流转向，(在各自的翼片参考系中)减缓空气流速度，且产生空气流的静压力的上升。在本发明的其他所希望的方面中，翼片的构造(连同其与周围的翼片的相互作用)及其周向表面对于级空气流效率而言提供了改善的空气力学、从级到级的平滑层流、减小的热应力、改善的级的相互关系以有效地使得从空气流在级间流通、以及减小的机械应力。典型地，多排转子/定子级叠置在轴向流动压缩机中以达到希望的排出-进入的压力比。转子翼片和定子翼片能够借助合适的接附构造从而固定到转子轮或者定子壳体上，例如通常已知的“根部”、“基部”或者“榫接部”(参见图2-5)。
压缩机2的级在图1中示范性地图示。压缩机2的级包括多个周向间隔的安装在转子轮51上的转子叶片22和多个周向间隔的接附到静态压缩机壳体59上的定子叶片23。每个转子轮接附到后驱动轴58上，其连接到发动机的涡轮机段上。转子叶片和定子叶片位于压缩机的流动路径1中。如本发明实施的，流经压缩机流动路径1的空气流的方向由箭头60所示(参见图1)。压缩机2的所述级仅作为本发明范围内的压缩机2的级的示范。所示的和所述的压缩机2的级并不意味以任何方式限制本发明。
转子叶片22安装在形成后驱动轴58的一部分的转子轮51上。如图2-6图示的，每个转子叶片22设置有平台61和大致轴向或者接近轴向进入的榫接部62，其用于与转子轮51上的互补形状的配合榫接部(未示出的)连接。然而，如本发明实施的，轴向进入的榫接部可以设置有翼片型面部分。如图2-6中图示的，每个转子叶片22包括转子叶片翼片63。这样，在翼片的总体形状中从平台61的中点处的翼片根部64到转子叶片末端65的任何截面处，每个转子叶片22具有转子叶片翼片型面(airfoil profile)66(参见图6)。
为了限定转子叶片翼片的翼片形状，提供了空间中独特的点的集合或者轨迹。该独特的点的集合或者轨迹满足级的要求，从而使得所述级能够制造。独特的点轨迹也满足希望的对于级效率和减小的热和机械应力的要求。点的轨迹借助使压缩机能够以有效、安全和平稳的方式运行的空气动力负荷和机械负荷之间的迭代得到。
如本发明实施的，该轨迹限定转子叶片翼片型面，且可包括相对于发动机的旋转轴线的点集合。例如，能够提供点集合以限定转子叶片翼片型面。
在下表中给出的笛卡儿坐标系X、Y和Z数值限定出转子叶片翼片在沿其长度的不同位置处的型面。如本发明实施的，发现该翼片能够作为第5级翼片定子轮叶得到应用。X、Y和Z坐标的坐标值以英寸列出，尽管当这些数值适当地转换时可以使用其它的尺寸单位。这些值不包括平台的圆角区。笛卡儿坐标系具有正交相关的X、Y和Z轴线。如用于转子的图7和用于定子的图8中图示，X轴线平行于压缩机叶片的榫接部轴线，其与发动机中心线成一角度。正的X坐标值为轴向向后，例如朝向压缩机的排气端。正的Y坐标值定向成垂直于榫接部轴线。正的Z坐标值对于转子叶片定向为径向向外朝翼片的末端，该末端朝向压缩机的静态壳体，且对于定子叶片定向为径向向内朝向压缩机的发动机中心线。
如图5中图示，仅用于参考目的，穿过沿叠置轴线的翼片和平台的交叉处建立点-0。在翼片的示范性的实施例中，点-0定义为参考段，其中上表的Z坐标为0.000英寸，其为离开发动机或者转子中心线的设定的事先确定的距离。
通过在垂直于X、Y平面的Z方向上的选定位置处定义X和Y坐标值，能够确定在沿翼片长度的每个Z距离处转子叶片翼片的型面段，例如但不限于图6中的型面段66。通过用平滑连续弧线连接X和Y值，能够固定在每个距离Z处的每个型面段66。在距离Z之间的不同表面位置的翼片型面通过平滑地彼此连接相邻的型面段66来决定，从而形成翼片型面。这些数值代表在周围环境中的、未运行的、或者非热条件下的翼片型面并且用于未涂敷的翼片。
表格数值产生且显示到3个小数位以便确定翼片的型面。存在典型的制造公差以及涂层，这在实际翼片型面中需要考虑。因此，对于型面给定的数值是对于标称翼片(nominal airfoil)而言的。因此可以理解，+/-典型制造公差例如+/-值以及任何涂层厚度可添加到X和Y值中。因此，在垂直于沿翼片型面的任何表面位置的方向上的大约+/-0.160英寸的距离限定出用于转子叶片翼片结构和压缩机的翼片型面包络线。换句话说，如本发明实施的，在垂直于沿翼片型面的任何表面位置的方向上大约+/-0.160英寸的距离限定出在标称的冷的或者室温的实际翼片表面上的测量点和在相同温度下这些点的理想位置的变化范围。如本发明实施的，转子叶片翼片结构对此变化范围是稳定的，而不损害机械和空气动力功能。
下表1中给出的坐标值提供了用于示范性的第5级翼片定子轮叶的标称的型面包络线。

还可以理解的是，上表1中披露的示范性的翼片可以几何地按比例增加或者减小以便在其他类似压缩机设计中使用。因此，表1中列出的坐标值可以按比例增加或者减小，使得翼片型面形状保持不变。表1中坐标的比例缩放型式可以由表1中的X、Y和Z坐标值乘以或者除以常数来表示。
虽然在此描述了不同的实施例，但是从本说明书中可以理解的是，本领域的技术人员可获得在本发明的范围内的不同元件的组合、改变或者改进。
