The application of the vorticity confinement technique to single-blade rotorcraft simulations, both in hovering and forward flight conditions, allows to improve the representation of certain features of the flow field but has a very limited influence on the predicted thrust. Comparison with experimental sectional blade loads shows localized improvements, mainly in the central region of the retraiting blade.

Abstract
The application of the vorticity confinement technique to single-blade rotorcraft simulations, both in hovering and forward flight conditions, allows to improve the representation of certain features of the flow field but has a very limited influence on the predicted thrust. Comparison with experimental sectional blade loads shows localized improvements, mainly in the central region of the retraiting blade.File in questo prodotto:
