The flow spatial structure in the flowing part of the LPC of a 200 MW steam turbine has been studied. Analysis for stages 1 and 2 has been conducted for design and partial-load operating conditions. A mathematical model and a computational analysis method has been developed for spatial viscous flow in turbo machine stages with account of elastic blading vibration by solving the coupled problem of nonstationary aero dynamics and elastic vibration of blades (there are no world analogs). Numerical analysis of nonstationary interaction of aero dynamic forces acting on the blades and of elastic blade vibration has been carried out for the rated and partial-load operating conditions of the last stage of the 200 MW turbine
