摘要：

The principal factors responsible for reduced economy and reliability of wet-steam turbines are refined. Aerodynamic characteristics of arrays (cascades) are given. The physical aspects for appearance of moisture in the cascades of stages are considered, the role of boundary layers being emphasized. It is established that there is a sharp change in pulsations upon transition through the Wilson zone. The desirability of employing intrachannel live-steam pressurization is noted. Problems are formulated for further research.
