Designing vertical take-off and landing (VTOL) unmanned aerial vehicles (UAV) requires precise propeller data for optimization. A propeller test bench is available at the institute of aircraft design at TUM. To determine its accuracy, previous measurements were compared to public data using the same propellers. This evaluation revealed deviations and led to a complete redesign of the hardware, software as well as additions of several environmental sensors for a precise measurement. The paper describes the problems encountered at the old test bench, develops solutions to counter them and shows the current state of the refurbishment. Several propellers have been tested and their preliminary propeller coefficients are presented.     «
