Abstract
Given the importance of the recent improvements made in the Laboratory of Fluid Mechanics and Hydraulic Machines of the Aeronautics Institute of Technology, this work was motivated to make one more of these improvements. Thus, an automatic data acquisition and control system was developed with application in the laboratory's Pelton turbine, using the commercial software LabView, from the National Instruments Company. The objective was to experimentally determine the performance curves of the machine under the condition of applying constant shaft force, for increasing flow rates. The curves obtained with the variations of manometric inlet pressure, rotation, shaft force, shaft power, hydraulic power, and efficiency as a function of the flow rate had the theoretically expected behavior, reaching the objective of this research. Possibilities for future work and improvements were identified in terms of changing the turbine's braking system, implementing control subroutines, and replicating the methodology to the other machines in the laboratory.
