Comparative Analysis Of Performances Of Different Motor-Propeller Combinations For The Characterization Of Electric Motors Efficiency

Abstract

This article presents a comprehensive characterization of electric propulsion systems, focusing on the performance of electric motors and propellers through wind tunnel experimentation. The study aims to deepen the understanding of the interrelation between key parameters-such as rotational speed (RPM) and incident airspeed-and their influence on overall system efficiency. The experimental setup, which integrates a continuous power supply and robust data acquisition methodology, enables precise and repeatable measurements. By conducting a wide range of tests under varying conditions, the research not only yields valuable insights into motor and propeller behavior but also establishes a solid foundation for the development of accurate multi-variable models. These models are essential for enhancing electric aircraft design, enabling improvements in autonomy, payload capacity, and operational range. Furthermore, the data generated can be directly integrated into existing flight simulators, providing a realistic basis for the performance prediction of electric aircraft. The methodology relies on the integration of a commercial test stand and software suite, enabling accessible and repeatable experimentation for the broader research community.
