Abstract
To evaluate the efficiency of a quadcopter propulsion system, tests were performed on an experimental bench, equivalent to 1/4 of the aircraft frame, using a AX-2810Q brushless motor, 10x4.5" and 8x4.5" propellers, along with 4A ESCs. In order to obtain better results, preliminary studies on mathematical modeling were performed considering the system based on the lever method. The parameters obtained were the thrust and the torque, aiming to evaluate the influence of the propeller diameter over the effectiveness of the aircraft. The bench was designed using SolidWorks 3D design software. Additionally to the physical tests, simulated tests were performed using the SolidWorks simulation tool to validate the results obtained experimentally. The employment of that tool made possible to visualize the behavior of the assembled structure according to the buoyancy variation. During the tests, vibrations observed in the structure were measured using a vibration sensor SW-420, in order to verify the interference of this phenomenon in the system.
