Preliminary Experimental Investigation of the Design-Overloaded Stage in Two-Stage Axial Turbine Test Rig

The article deals with the issue of experimental research so-called design overloaded stage. A new device enabling measurements on two-stage axial turbine is advantageously used in this task. setup designed so that a preparatory stage included front examined introduces some aerodynamic overload already flow path phase. This program focused primarily effect leakage flows and their mixing mainstream. paper describes verification newly introduced arrangement reveals first data obtained.
