This paper describes the experimental activities aimed at developing two axial turbine stages. The first stage is representative of a high-pressure transonic design with stator and rotor cooling performed also in the experimental setup; the second is a low-pressure uncooled stage with strong transonic effects. The testing took place in the unique Graz University of Technology experimental facility. The present paper includes a description of the stage test configuration with particular reference to the cooling system, and the main outcomes of the test runs between January and June 2001 are presented. This activity was performed as part of the BRITE/EURAM Project ‘DITTUS’ under support from the European Union.
