This work contains the simulation results of vortex ring state appearance and evolution around main rotor of a helicopter. These calculations were based on solution of Navier-Stokes equations using the Fluent code. During these simulations an actuator disc model of fan has been used. This model assumes that a fan is a pressure jump generating surface. Two meshes have been used during this simulation: three dimensional and axisymmetric two dimensional. The most of the cases has been calculated using steady flow solution, but unsteady model also has been applied. Main goal of this work was a calibration of model, in terms of simplifications influence on results, and also in comparison with experimental results. It is assumed, that after a proper calibration, this model can be used in further flight safety methods of VRS elimination research.
