Abstract: A compressor airfoil has a leading edge, a trailing edge, and a radially outboard edge connecting the leading edge and the trailing edge. The leading edge is formed according to a leading edge tip profile and the trailing edge is formed according to a trailing edge tip profile. The leading edge tip profile and/or trailing edge tip profile has a chamfer and/or a radius. In this manner, contact stress experienced by the compressor airfoil such as upon contact with a surrounding abradable seal are ameliorated. The leading edge tip profile and/or trailing edge tip profile are coated with an abrasive coating such as to enhance fitting of the abradable seal to the path of the compressor airfoil upon such contact.
Abstract translation: 压缩机翼型件具有连接前缘和后缘的前缘，后缘和径向外侧边缘。 前缘是根据前缘尖端轮廓形成的，后缘根据后缘尖端轮廓形成。 前缘末端轮廓和/或后缘末端轮廓具有倒角和/或半径。 以这种方式，可以改善压缩机翼型的接触应力，例如与周围的可磨损密封件接触时的接触应力。 引导边缘末端轮廓和/或后缘末端轮廓涂覆有磨料涂层，以便在这种接触时增强可磨损密封件与压缩机翼型件的路径的配合。
