Abstract [en]

An experiment was designed based on the design of experiment method to evaluate the uncertainty in Kaplan CAM curve determination. The variation is negligible around the best efficiency point, below the estimated measurement error. The variations in efficiency are at their largest before the propeller top and may vary between a high efficiency and significantly lower efficiency at this point. Additional measurements are recommended to capture such behaviour. There was no clear indication of a hysteresis in the runner blade or guide vanes mechanism. However, a constant difference in the readings between the fixed scale and the station sensor was observed
