摘要： Disclosed is a method of manufacturing an airfoil structure. The airfoil structure includes a plurality of airfoils, a support for supporting the airfoils, and a case for covering the airfoils. Each airfoil includes an airfoil body, and an airflow generator for producing induced airflow by generating plasma. The method includes a process of forming the airflow generator that includes a first electrode forming step of forming a first electrode on the airfoil body, a dielectric layer forming step of forming a dielectric layer on the airfoil body by forming ceramic powder into a film to cover the first electrode through room temperature impact consolidation, and a second electrode forming step of forming a second electrode on a surface of the dielectric layer, such that the second electrode is electrically connected to the first electrode, and an alternating-current voltage is applied to the second electrode.
