摘要： PURPOSE: A hollow type fan blade tuning using distinct filling materials is provided to select a first material in order to supply additional rigidity to a fan blade and to select a second material in order to include excellent attenuation characteristic. CONSTITUTION: A hollow type fan blade tuning using filling material comprises a main body extended from between a front end corner and a rear end corner and channels formed in a main body. A plurality of ribs is extended in the center of the channels. The fan blade includes a dove foil and an airfoil extended from the dove foil to the outside of a radius direction. Two or more materials are accumulated in the channels. A first material is selected in order to supply additional rigidity to the fan blade, and a second material is selected for attenuation characteristic.
摘要翻译：目的：提供使用不同填充材料调整的中空型风扇叶片，以选择第一材料，以便为风扇叶片提供额外的刚度并选择第二材料以便包括优异的衰减特性。构成：使用填充材料调节的中空型风扇叶片包括从前端角和后端角之间延伸的主体和形成在主体中的通道。多个肋在通道的中心延伸。风扇叶片包括鸽子箔和从鸽子箔延伸到半径方向的外侧的翼型。两个或多个材料在通道中累积。选择第一材料以便为风扇叶片提供额外的刚性，并且选择第二材料用于衰减特性。
