This work demonstrates that a mid-fidelity viscous surface-vorticity panel method can accurately predict propeller performance in aerodynamic ground effect, including tilted configurations. With errors below 5% in key thrust metrics, the approach enables fast, reliable evaluation for UAV and eVTOL design in near-ground operations.
