CONDUCTING AERODYNAMIC ANALYSIS OF THREE-DIMENSIONAL MODELS OF QUADCOPTER PROPELLERS

Abstract

The widespread use of multicopters, in particular quadcopters, in the civil, industrial and defense sectors necessitates the improvement of their aerodynamic characteristics in order to increase maneuverability, energy efficiency, load carrying capacity and reduce noise level. One of the key elements affecting these characteristics is the design of the propellers. Despite significant progress in the research of propellers for classical aviation, research for multicopters remains quite limited.

The aim of the work is to conduct a comparative aerodynamic analysis of four three-dimensional models of the HQProp V1S 7x3.5x3 propeller using the modern SolidWorks Flow Simulation software. The research methodology involves computer modeling of three-dimensional models of the real propeller, created by the author using the master-model method and the shell method, as well as 3D models obtained from specialized internet resources.

The main parameters of the analysis are the distribution of air flow velocities, pressure distribution, calculation of lift and drag force, as well as the influence of the angle of attack on the aerodynamic properties of the studied samples. The results of mathematical calculations demonstrate the differences between the models.

The scientific novelty and practical significance of the research is that the author obtained original data on the aerodynamic characteristics of 3D models of the HQProp V1S 7x3.5x3 propeller, which were not previously published in the open press. The mathematical modeling technique used and the results obtained thanks to it will be used in the future to design new, more advanced propeller models, which will contribute to improving the overall efficiency of the UAV.
