Experimental study of propellers for the electric propulsion system

Abstract

The choice of propeller geometry in the electric propulsion of an aircraft has a significant impact on its performance. There are few studies devoted to the experimental testing of propellers dedicated to this type of propulsion. This paper presents the results of an experimental study of the propellers for the electric propulsion system. Selected parameters related to the performance of a set of 12-inch plastic propellers with different pitch values were analyzed in the study. The tests were carried out on a constructed test stand which enabled the adjustment of parameters such as rotational speed or voltage of the electric motor. The test stand was equipped with a set of sensors that allow the recording of defined parameters. The obtained results give general knowledge about the performance of the propellers with different pitch values under static conditions and constitute the basis for further research under forced airflow conditions.
