Abstract : Values of optimum blade chords in stages with shroudless blade rims were determined taking into account all losses of shroudless stages, whose blades are twisted according to the rule for a potential flow. The discussed method of calculating the optimum chord value satisfactorily agrees with experimental data obtained on non-twisted blades in the turbine blading. (Author)
