Marine propellers are essential components of many watercrafts,and their performance depends on various factors such as geometry,material,speed,and pitch ***,in this study,we demonstrate the main elements and working principle of a marine *** also explain the main principle of lift and drag force and its effects on propeller's design and ***,we demonstrated how a propeller can be tested in realistic *** studying previous designs and patents of marine propeller test platforms,some limitations have been found and *** address these limitations,the main objective of this study has been set to develop a propeller test platform that can measure the thrust and torque of different propellers with high accuracy and *** setting the suitable requirements and designing the propeller test platform,we propose a new design of a marine propeller test platform that uses a swing arm mechanism to fix the propeller under water and sense its thrust force while keeping the main motor and the frame *** design allows us to get high sensitivity measurements continuously and precisely without being affected by the motor and frame *** the mentioned design,a well-balanced mechanism has been achieved with high sensitivity thrust measuring *** platform could sense small forces of about 0.001 kgf,which is essential for evaluating the performance of low-thrust ***,we achieved a power train that can deliver up to 22 k W of power to the propeller with up to 1500 rpm of rotational speed suitable for most mid-sized propellers,and that with torque consumption up to 70 N·m which allows us to test a wide range of propellers with different power and speed *** to the previously used platform,this new design can be up to 120 times faster than old test platforms when it comes to changing *** achieved propeller test platform can hold up to 2500 N of thrust force an
