ESTIMATION OF THE EXTENT TO WHICH RADIALITY INFLUENCES THE FLOWING PART OF THE COMBINED ENGINE TURBINE

In the present work influence of a degree of radiality on characteristics of the radially-axial turbine working under conditions of a non-stationary stream of pulse system of pressurization of the combined engine is shown. All predictions are conducted using the complex approach proposed earlier by authors that combine the positive aspects of both mathematical models now in use and methods of cal-culation and designe of the turbine.

Keywords: the complex approach, a degree of radiality, factor of a pressure, the characteristic of the turbine, one-dimensional quasistationary approach, a flowing part, radially-axial turbine.
