Abstract
The final approach and touchdown of a landing aircraft is studied numerically with different hybrid Reynoldsaveraged Navier–Stokes (RANS)/large-eddy simulations (LES) approaches. Particular emphasis is put on the ground effect and the wake vortex evolution before and after touchdown. Additionally, the effect of the landing gear on the aircraft’s aerodynamics during landing is analyzed. The near field around the landing aircraft is generated using two different RANS methods. In a number of steady-state simulations the altitude of the aircraft above ground was varied in fixed steps. Furthermore, a simplified continuous landing maneuver was simulated by applying unsteady RANS simulations.
