Abstract: To address the incompatibility between the aircraft body and the propeller due to configuration changes during low-altitude aircraft upgrade, an investigation was conducted using the NACA 2414 airfoil as a case study. On the basis of flight requirements, the propeller geometry was designed using Profili software, and a three-dimensional model was constructed in SolidWorks through a layer-by-layer lofting method. Ansys software was employed to simulate and analyse the variations in lift, noise, deformation, and fatigue life of the propeller under aerodynamic performance conditions, revealing the power output, noise generation, and safe operational cycle of a carbon fibre propeller under different rotational intensities. Results indicate that, the constructed propeller can generate a lift force of 403.77 N at a rotational speed of 3000 RPM, meeting the safety requirements for the aircraft's maximum take-off weight (255.4 kg). In addition, at this rotational speed, the noise level is approximately 70 dB, and the maximum deformation is only 0.366 mm. When the rotational speed is adjusted to 1Ã--105 RPM, the propeller blades can operate safely for 34.7 h before failure occurs. [ABSTRACT FROM AUTHOR]
