1) blade casing
叶片造形
3) "leaf" construction
"叶片"构造
5) rotor blade forging
叶片锻造
1.
Collapse often happens on the parting face in rotor blade forging process because of the complex shape with torsional angle,variable cross-section and chord length,and using difficult-to-form materials,thus the rotor blade forging die need to be repaired frequently.
叶片锻造模具因为叶片形状复杂,变截面、变弦长、有扭角,且叶片材料一般为材质优、价格昂贵难变形的材料,锻造时模具在分模面处容易出现塌陷,常需修整模具。
6) skewed blade
掠形叶片
1.
The mechanisms of an axial fan with skewed blades in reducing noise are analysed.
分析了掠形叶片轴流叶轮的降噪机理。
2.
The axial fans with skewed blades widely used in engineering practices are studied, and during the study, the blade is divided into N elementary sections in radial direction.
通过将掠形叶片沿径向分为N个叶元体，推导了第k叶元体与气流相互作用诱发的叶元体尾缘涡流噪声模型与轴流风机的涡流脱落声学模型，通过实验验证了理论模型的正确性，并分析了叶轮结构参数与涡流脱落噪声的关系。
