Adaptable test rig for two-stage axial turbine

Abstract: This contribution describes a new test rig for a two-stage axial turbine built in the VZLÚ. 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 import… Show more

“…Fig. 3 shows the vibrations as a function of rotational speed for the case of a two-stage turbine in comparison with a single-stage turbine operated during the start-up phase of the device [4]. It demonstrates sufficient dynamic stiffness of the measurement device and indicates the smooth operation of future operation in experiments with a twostage turbine assembly.…”
