The effect of helicopter rotor blade tip shape on overall aircraft noise level is analyzed, in forward flight conditions. The infamous HART-II experimental data is used as a base for validations. Commercially available CFD software Ansys/Fluent is us

In the present work, a numerical methodology is developed for affordable and accurate analysis of helicopter rotor noise in forward flight. The flow field is obtained using unsteady compressible flow analyses using commercially available computationa

The HART II test of 2001 provided a significant and comprehensive database of rotor loads, blade motion, blade pressure distribution, acoustic signature and flow field data. A sub-set of these were released for public access worldwide and an Internat

One major difficulty in the design of quiet rotor blades is the correct numerical prediction of blade vortex interaction (BVI) noise in descent flight. Current second order spatial discretization schemes inherently have too much numerical dissipation

The TAU-HOST coupling chain for Fluid-Structure Interaction (FSI) simulations of active helicopter-rotors is validated by computing the HART II experiment. The result accuracy of the unstructured flow solver TAU is investigated in the case of a rotor
