The paper presents results of the low pressure turbine’s model stage (LPT) experimental investigation at the Reynolds number in the range of 13000 – 130000 and stationary linear cascades at the Reynolds number in the range of 50000 – 500000. The acquired data was used to have made the generalization of the low Reynolds numbers' influence on losses in vane's and blade's rows.
