FIELD: mechanical engineering; turbines. SUBSTANCE: rotor of two-stage turbine has two intermediate disks placed between working disks and provided with plates and rims with support and cantilever parts. Ratio of length of support part of rim of intermediate disk between disk plate and end face of adjacent working disk to length of cantilever part of rim of intermediate disk is 1.4-2.5. EFFECT: enhanced reliability of rotor owing to prevention of breakage of intermediate disks caused by asymmetrical loads. 2 dwg
