Upgrade Transonic Compressor Test Rig Data Acquisition System

Abstract

This thesis presents an upgraded data acquisition system (DAS) for the transonic compressor test rig (TCR). The legacy DAS acquired and processed pressure, temperature, and rotational speed data. The data were mass averaged, and the performance of the compressor was measured and compared to that acquired by the legacy system. Total-to-total pressure ratio and isentropic efficiency versus corrected mass flow rate were compared at speeds of 70 , 80 , 85 , and 90 of the design speed. The legacy DAS was robust but outdated compared to currently available technology. This thesis documents new hardware from National Instruments that was procured and integrated into the DAS. New software programming using commercial-off-the-shelf- software (NI-MAX, DsaLink3, and MATLAB) for acquiring data, processing data, displaying results, and generating reports was also implemented and documented. Data output files between the legacy DAS and new DAS were within reasonable tolerances and all functionality of the system was maintained.
