The conceptual design of eVTOL aircraft is a high-dimensional optimization problem that
involves large numbers of continuous design parameters. Therefore, eVTOL design method …

The accuracy of several computationally inexpensive acoustic frequency methods is
evaluated across a range of propeller geometries and operational conditions. The acoustic …

In this paper, a multidisciplinary optimization design method and its verification of low-noise
aircraft propellers considering aerodynamics, noise, and structural strength were carried out …

The rapid growth of drone use in urban areas has prompted authorities to review airspace
