Influence of the Ground Effect on the Precise Landing of an Unmanned Aircraft

Abstract

This paper examines a multi-rotor unmanned aerial vehicle and the influence of the ground effect on the aircraft during the landing stage. Theoretical and practical research of other authors and results are described. It is briefly discussed how the position of the high-pressure area changes with changing environmental conditions. The study examined the ground effect on the drone at 1/3R - 2R. Calculations show that the propeller thrust increases up to 7%. Also, discussing the results, it has been hypothesized that an increase in thrust near the ground will reduce engine speed, which may directly impact the drone's stability and landing accuracy. Further research is needed to explore this issue further.
