Adaptable test rig for two-stage axial turbine

This contribution describes a new test rig for a two-stage axial turbine built in the VZLU. The test rig has replaced an original facility used for a full stage aerodynamics investigation. The motivation for the design of the new test facility was the limitations of the original one. The design is briefly discussed, and then the first measurement results are presented. The first operation was performed with a turbine stage already measured in the original facility. This allows the comparison of the most important quantities.
