초록

A method of improving aerodynamic performance of foils by the application of conformal, elastomeric vortex generators. The novel use of elastomers allows the application of various forms of vortex generators to sections that have been problematic from engineering and cost considerations. A novel and efficient vortex generator profile is identified, which develops an additional co rotating vortex at low energy expenditure. The mechanisms allow for the application of transverse vortex generators, or Gurney Flaps/Lift Enhancement Tabs/Divergent Trailing Edg...

청구항

1. An application of passive, flexibly attached geometry, elastomeric vortex generators lift enhancement tabs for improving flow on a foil or series of foils, thereby improving lift, drag, angle of attack capability or lift to drag ratios, comprising: passive means for providing an element for forming transverse vortices, and a base surface for attachment to a foil or aero/hydrodynamic surface, wherein said passive means for providing an element for forming said transverse vortices is elastomeric and is configured to be bonded to the foil or aero/hydrody...
