FIELD: engines and pumps. ^ SUBSTANCE: two-stage turbine rotor comprises first-stage turbine, second-stage turbine and intermediate disk arranged in interdisk chamber. Inner surface of the hub of every disk is cylindrical at its center and changes into conical surfaces toward disk hub edges. Note here that disk hub width-to-cylindrical surface width varies from 1.5 to 6 while generatrix angle of disk hub conical surface taper makes 5-15. ^ EFFECT: higher reliability due to uniform distribution of strains over hub inner surface. ^ 1 dwg |
