目前,国内外在航空发动机空心导流叶片的加工技术大多采用以下成形方法:(1)充蜡成形;(2)聚(?)酯成形;(3)爆炸成形;(4)液电成形。上述四种工艺方法各有其优、缺点。本文介绍空心导流叶片的另一种成形工艺,可作为上述成形工艺方法的补充。空心导流叶片的理论型面座标草图见图1,实际产品图见图2。 At present, most of the processing techniques of aero-engine hollow guide vanes at home and abroad adopt the following forming methods: (1) wax forming; (2) poly (ester) forming; (3) explosion forming; The four methods have their own advantages and disadvantages. This article describes another type of hollow guide vane forming process that can be used as a supplement to the above forming process. Hollow guide vane theoretical profile standard sketch shown in Figure 1, the actual product map shown in Figure 2.
