Abstract
In the conception of an aircraft project, it is essential to perform a detailed performance analysis in all phases of flight to affirm whether the aircraft will obtain the performance required to meet the project requirements. Therefore, it is important to get accurate data regarding the performance characteristics of the propulsion system that will be used. The present work aims to present a methodology for constructing a low-cost test bench capable of characterizing the performance of electric propulsion systems. To assist in the selection of the engine and propeller that best meet the needs of the Unmanned Aerial Vehicles (UAVs) designed by the Uirapuru Aerodesign UFPA team, intended for the SAE Brazil Aerodesign competition. First, the sizing of the structures took place after the analysis did the Ansys® software, selecting components and sensors, and then the fabrication and realization of tests. The projected bench can simultaneously measure data of electrical power, rotation, and thrust generated by electric motors for the different propellers analyzed and presents as a priority the simplification of the structure and the use of components and sensors that enable a high precision of the collected data. This guarantees the resistance of the bench; a structural analysis was performed using the Finite Element Method (FEM) in the Ansys® software. For the operation of the electrical circuit, the simulation of the electrical components was conducted in the Proteus® software. Due to its low construction cost, structural simplicity, easy implementation, high precision, and reliability in the results obtained, the proposed test bench proved to be a viable and practical solution to get performance data from electric propulsion systems, such as thrust, rotation, and electric power, allowing to characterize the most efficient propulsion system for flight.
