The Large Scale Rotating Rig at NAL is designed to carry out detailed experimental investigations of the flow through compressor and turbine stages. Instrumentation and data acquisition system (DAS) for stationary and rotating frame measurements, pressure distribution measurements across the vane and the blade surface and the flow measurement was developed in-house. This enabled making pressure measurements on the vane surfaces, blade surfaces, platforms and at the vane/blade exit wake flows. There were added challenges in terms of unsteady pressure measurements, transferring of data from rotating frame and condition monitoring of the rig. The DAS is developed using state-of-the-art instruments and is coupled with a GUI data acquisition software developed using LabVIEW to tackle all these challenges. This paper presents elaborated details of the multichannel instrumentation and the DAS.
