Abstract:The cone gear spoke fracture is briefly described for a typical turbofan. On basis of checking and analyzing, the reason of failure is ascertained. To establish and verify the failure mode, trouble reappearing and low -cycle fatigue tests are conducted on component test rigs. Verification test is carried out for modified cone gear and the satisfying result is acquired.
Keywords:turbofan  cone gear  spoke fracture
