| Abstract: | The five design concepts of low cycle fatigue life（LCF） test for an aeroengine fan disk,compressor disk and turbine disk were analyzed.The reliability and failure rate of the test disks were calculated at reaching the given life.The calculations were compared with the standard demands.The improvement concepts were proposed for solving the problems that the reliability and failure rate can not reach the standard demands. |
