Abstract The fatigue damage of 2 central components of helicopter rotor hub is analyzed comprehensively by inspecting the fracture area appearance, analyzing macroscopic and microscopic morphology, energy spectrum and infl uence of machining process, verifi cation of supplementary testing. The main reasons and improvement of central component damage are confi rmed, which provides the value experiences for the failure analysis and manufacturing technology of titanium component of helicopter rotor system.
