The goal of the thesis is the design and construction of a device for measuring the thrust and efficiency of ship propellers. The beginning of the work presents the theoretical foundations of the operation of a ship propeller. This is followed by the presentation of the process of creating a device for testing the ship propeller in an open water chanel, where the water in the channel is stationary, while the propeller, and the measuring equipment, moves. The geometry of the measured propeller was based on the freely available 3D model of the Potsdam propeller (PPTC). To measure the characteristics of the ship propeller, we first determined the operating points based on dimensionless numbers. Measurements were carried out at three rotational speeds of the propeller and different advance coefficients. We compared the results of the measured quantities with the reference measurements of the PPTC propeller and found similar trends. In the conclusion of the work, possible improvements to the device are presented, and suggestions for further work are provided.
