Abstract：

In　order　to　solve　the　problem　of　measurement　for　the　LTE　(Leading　and　Trailing　Edges)　of　ultra-thin　blades,　a　new　method　for　LTE　measurement　based　on　feature　modeling　is　proposed　in　this　study.　The　accurate　coordinates　of　blade　profile　are　collected　using　a　high-precision　laser　probe　based　on　conoscopic　holography　principle,　and　the　fast　and　precise　measurement　of　LTE　is　achieved　based　on　feature　modeling　technology.　The　research　results　show　that　the　method　proposed　in　this　study　fully　considers　the　geometric　characteristics　of　blade　profile　and　can　effectively　extract　the　geometric　information　of　LTE　by　optimizing　the　number　and　location　of　sampling　points.　This　method　improves　the　accuracy　and　efficiency　of　LTE　measurement　significantly,　which　provides　a　new　technical　solution　for　measuring　the　LTE　of　aeroengine　blades.　©　2019　IEEE.
