Investigation of Propeller and Airframe Interaction on UAV

Abstract

In this article, within the framework of the project “ Development of multi-purpose fixed-wing drone based on innovative solutions and the creation of necessary competencies”, our task was to examine a propulsion system mounted on an unmanned fixed-wing aircraft. We started the research by evaluating the results of the wind tunnel measurement. From the measurement data, we determined the characteristic curves of the propulsion system installed on the aircraft. We estimated the aerodynamic characteristics of the aircraft using the XFLR5 program. The operating conditions of the propeller in horizontal flight were determined from the results. It was found that the propeller fit is adequate at stall speed, but less than optimal at cruising speed.
