THE EFFECT OF AXIAL CLEARANCE ON THE DYNAMIC STRENGTH OF ROTOR BLADES OF AXIAL-FLOW TURBINES

The report deals with the problem of increase of the dynamic strength and the reliability of blading of marine type turbines. Dynamic bending stresses during sympathetic vibrations are investigated. Optimum axial clearances, at which the efficiency of the turbine stage is maximum are sought. The VS-1 air vibration stand is used for tests. (Author)
