NUMERICAL SIMULATION OF MODEL HELICOPTER ROTOR IN HOVER

Blog Article

The article presents details of a URANS simulation of the flow field near a hovering model of the Caradonna and Tung Holders (1981) helicopter rotor [1].The CFD code SPARC [2] proves to be capable of capturing the aerodynamics of a two -bladed rotor in high-speed transonic hover conditions.A comparison of the simulation results with the experimental data Contact Lens Solutions is acceptable, hence the described methodology might be used with confidence in future numerical studies of application of noise-reducing devices on helicopter blades.
