摘要
统计了一些航空发动机风扇叶片凸肩的结构参数 ,探讨了凸肩的形状、位置、厚度、紧度、涂层等对叶片振动特性的影响 。
The structural parameters of mid-span shrouds are given for aircraft engine fan blades. The effects of shroud contour, location, thickness, tightness and coating are investigated on blade vibration characteristics. The experimental verification has evidenced that the reduced blade-tip vibration and the extended shroud life can be obtained with the increased tightness.
