FIELD: machine building.SUBSTANCE: rotor blade having a platform, a body part, connected to the platform, and a surface finished at the end part and having an aerodynamic shape in the cross section. The thickness of the rotor blade varies depending on its height according to three different linear functions: T=-0.8646*h+1.1087, T=-1.0209*h+1.2058, T=-0.7618*h+0.9985, where h is the percentage of the blade height. The blade thickness can be put in compliance with the operation characteristics of the turbine unit.EFFECT: characteristics optimisation.10 cl, 1 tbl, 5 dwg |
