Abstract

Methods of calculation of losses of efficiency of the axial turbine with the driving wheel with a bandage are analysed at a partial supply, results of a complex pilot study of axial turbines are presented at change of gaps and a number of parameters, settlement research and on the received results is carried out them formulas for turbines with a working wheel with a bandage are corrected.
