| Abstract: | Variable speed axial compressors have untuned blades. Taking a gas turbine set as an example, the dynamic strength of the axial compressor's blades are being calculated by way of computing their dynamic stresses. Hereby the blades' margin of safety is got, and, by taking into account the comprehensive vibration resisting strength of the material, a simple and feasible way of dealing with blade failure is being suggested. Many years of operation have proven this to be a safe and reliable way. Figs 2, tables 2 and refs 5. |
