As the connecting part of the compressor blade-disk structure, the groove bears a variety of loads and is one of the most important parts, especially in the field of gas turbines. The strength analysis and structure optimization of the dovetail compressor blade disk were carried out. Based on the blade-disk model, using standard strength analysis, under the full load calculation of temperature, rotating speed, and aerodynamic pressure, the sensitivity analysis of structural parameters such as stagger angle, root length and root-groove location height was performed. Finally, combined with the sensitivity analysis, the optimization of the blade-disk structure was studied. The results show that reducing stagger angle of the blade root and increasing the height of the root groove position can effectively reduce the groove stress.
