发明名称 An installation for shaping a hollow blade
摘要 A hollow blade is shaped by superplastic inflation of a blank made up of welded-together sheets. A die comprising two hollow shapes clamping the outline of the blank is placed inside an autoclave-forming enclosure in order to subject the blank to superplastic inflation, and the two hollow shapes are united by U-shaped clamps made of a material having a coefficient of thermal expansion that is smaller than that of the material constituting said shapes.
