Abstract
The paper analyzes the problem of the operation of an unmanned aerial vehicle with ducted fan propulsors in hovering mode over a flat landing platform. Numerical calculations of gas dynamics were carried out using the traditional approach to turbulence simulation based on averaged Navier–Stokes equations and using the eddy-resolving method of large eddies. The results obtained which confirm a need to use eddy-resolving approaches.
