| Abstract: | This paper examines the acceptability of inlet distortion from the angle of to the blade strength,and considers the influence of some inlet distortion patterns on the compressor blades vibration.An analytical moethod is provided.Meanwhile,the exciting forces of the circumferential distortion on the compressor blades and the blade responses to these fores are analyzed.The blade vibratory stresses caused by the distortion are calculated.The stress variation at different distortion levels is also investigated,and so the inlet distortion tollerance limit determined by the blade strength is discussed. |
