涡轮机翼型侵蚀测定
摘要：
本发明涉及涡轮机翼型侵蚀测定。一种系统可包括至少一个计算机装置，其构造成获得在使用后的涡轮机翼型上的特定径向位置处的前缘的二维已使用轮廓。系统将涡轮机翼型的二维已使用轮廓的相对大致直线对准部分与先前获得的、二维基线轮廓的相对大致直线对准部分对准。每个轮廓的对准部分处于涡轮机翼型的大致相同径向位置。已使用轮廓与基线轮廓的比较测定已使用的涡轮机翼型在特定径向位置处的前缘是否已经侵蚀。系统还可包括用于测量涡轮机翼型的激光轮廓仪。
摘要（英）：

The invention relates to turbomachine airfoil erosion determination. A system may include at least one computer device configured to attain a two-dimensional used profile of a leading edge at a specified radial position on a turbomachine airfoil after use. The system aligns opposing substantially straight alignment portions of the two-dimensional used profile with opposing substantially straight alignment portions of a previously attained, two-dimensional, baseline profile of the turbomachine airfoil. The alignment portions of each profile are in substantially identical radial locations of the turbomachine airfoil. Comparing the used profile to the baseline profile determines whether the leading edge at the specified radial position of the used turbomachine airfoil has erosion. The system may also include a laser profiler for measuring the turbomachine airfoil.
