| Abstract: | The fiber-reinforced, dual-web and blisk turbine disk were introduced to reduce the stress and weight and increase the thrust-weight ratio of aeroengine. The future development of these advanced turbine structure was proposed. The strength contract analysis and weight calculation between the traditional turbine disk and three kinds of advanced turbine disk were conducted by the finite element analysis software. The results show that the three kinds of advanced turbine disk structures have superiority in aspect of strength and weight comparing to the traditional turbine disk, and all these advanced turbine disk structures can be used in the future aeroengine with high thrust-weight ratio after all the comparable critical technologies are obtained |
