Beschreibung

The MERIT Test Rig (pictured) is a Whirl Tower designed specifically for dynamic stall investigations in a rotating system. Due to the unpredictability and harsh loads experienced during dynamic stall, the motor is overscaled at 85 kW, to ensure it can maintain a constant RPM value and does not get damaged by unexpected aerodynamic occurrences. However, this means that the electromagnetic field surrounding the motor, as well as the cable supplying electricity, has a measureable impact on the quality of the data from the sensory equipment. This is most drastically seen in the force gauges, wherein even just supplying the power to the motor at 0 rpm causes large amplitudes to be seen in the measured signal. The thesis would involve first conducting a literature review, wherein common problems and solutions may be assessed. While some preliminary work has been conducted, prompted by observations during routine tests, a comprehensive and quantitative analysis has not been conducted yet.
