High resolution computation of the aerodynamics and acoustics of blade vortex interaction [PDF]
, 2008 In the present work, high resolution CFD simulations have been performed on an idealised problem of the interaction of an independently generated vortex with a rotor blade, including a case where the vortex directly impacts on the blade.

Influence of blade-to-blade dissimilarity on alleviation of helicopter blade-vortex interactions
Mathematical and Computer Modelling, 2001 This paper numerically examines possible alleviation of parallel blade-vortex interaction (BVI), experienced by helicopters in low-speed descent, through the introduction of blade-to-blade dissimilarity. A four-bladed rotor with two sets of opposite blades is considered, and the radius of one set is reduced to 80% of the baseline radius.
