This study examines the structural and aerodynamic performance of a hexarotor drone with a flat rotor configuration using ANSYS Engineering Simulation Software. The analysis focuses on the drone’s structural response to mechanical forces, including self-weight and torsional moments at maximum propeller speed, while also identifying potential resonance issues. Structural evaluations include static analysis of deformations, displacements, von Mises stresses, and the safety factor, alongside modal analysis of natural frequencies and dominant vibration patterns. The aerodynamic assessment explores air velocity, pressure distributions, flow interactions, and turbulence kinetic energy during stationary flight. Results, presented through analytical reports and graphical representations, are compared qualitatively and quantitatively to evaluate their impact on drone performance. The findings highlight the influence of modeling parameters on operational conditions and the drone’s ability to perform its intended functions.

摘要

This study examines the structural and aerodynamic performance of a hexarotor drone with a flat rotor configuration using ANSYS Engineering Simulation Software. The analysis focuses on the drone’s structural response to mechanical forces, including self-weight and torsional moments at maximum propeller speed, while also identifying potential resonance issues. Structural evaluations include static analysis of deformations, displacements, von Mises stresses, and the safety factor, alongside modal analysis of natural frequencies and dominant vibration patterns. The aerodynamic assessment explores air velocity, pressure distributions, flow interactions, and turbulence kinetic energy during stationary flight. Results, presented through analytical reports and graphical representations, are compared qualitatively and quantitatively to evaluate their impact on drone performance. The findings highlight the influence of modeling parameters on operational conditions and the drone’s ability to perform its intended functions.
