New methodology holds promise for rotorcraft wake prediction

Predicting tail shake and rotor wake is a major problem in rotorcraft, NCSA Article Cover requiring numerous wind tunnel and flight tests that eat up time and money. The National Center for Supercomputing Applications (NCSA) reports on the work of Intelligent Light's Applied Research Group in developing a new methodology that offers a solution. Fusing a standard grid-based finite-difference (Eulerian) CFD software with a vortex particle method, the researchers leveraged GPU computing to create and test a simulation software that would more accurately predict rotor wake interactions. The research is part of a five-year rotorcraft CFD project for the US Army's Vertical Lift Research Center of Excellence, based out of Penn State University.  This article is currently featured on the NCSA website.
