Abstract

The summary: results settlement, experimental researches of backlashes on EFFICIENCY of axial turbine stages Are resulted, the method of the account of losses from a radial backlash when losses basically are defined by size of leak of a working body through a radial backlash is given. Comparison of an offered method with known of the literature and with the spent experiments is spent. Accuracy of calculation is raised.

Keywords:

axial turbine stages, consumption coefficients, clearances.
