To the question about the distribution of the aerodynamic wakes in the integrated turbine system of gas turbine engine

Abstract

The article presents the results of an experimental study of the distribution of an aerodynamic wake in an integrated turbine system of a gas turbine engine. The source of the aerodynamic wake was a spoke-wheel installed at the input of the model interturbine duct, the area ratio of which varied in the range of 1 ... 2.2. The velocity profiles in the aerodynamic wake are obtained for different flow regions. According to the results of the study, a relationship was obtained between the area ratio of the model interturbine duct and the relative length of the duct corresponding to the decrement of the aerodynamic wake.
