Abstract

Abstract: There are some inevitable manufacturing error between real blade and designed one. In order to acquire the effect of manufacturing error on aerodynamic performance，four sets of plane cascades had been designed and manufactured to simulate different manufacturing errors including leading edge error and profile error. And experimental investigation based on plane cascade had been done to fulfill the research. The results show the leading edge error and positive profile error deteriorate the performance up to 23.4% and 40.1% respectively，while negative profile error improves the performance up to 16.6%. The conclusions can provide reasonable manufacturing technology requirement and criteria of blade evaluation.

摘要： 压气机叶片在加工过程中不可避免的会产生一定的加工误差。为了研究加工误差对压气机叶片气动性能的影响，设计并加工了4套平面叶栅用于模拟加工中常见的前缘及轮廓误差，并通过平面叶栅吹风试验获取误差影响规律。研究结果表明，前缘形状误差及正轮廓误差使得性能下降，前者使得叶型损失最高增加了23.4%而后者使得叶型损失最高增加了40.1%；此外负轮廓误差使得叶型性能有所提高，最高使得叶型损失降低16.6%。对应的影响规律可以用于提供合理的加工技术要求及制定合理的叶片检测标准。
