초록

A vortex generator mounted to an upper lifting surface of an airfoil, and having an upstanding generally planar vortex generating member. The forward edge portion of the member slants first upwardly and rearwardly from the airfoil surface, and then curves in a continuous convex rearward curve to blend into a substantially horizontal rearwardly extending upper edge portion. This vortex configuration alleviates unwanted secondary vortices.

A vortex generator adapted to be mounted to a forward surface portion of a substantially continuous aerodynamic lifting surface over which there is an airflow along a flow path from the forward surface portion where boundary layer air is at a generally predetermined thickness, to a rear surface portion of the aerodynamic surface where the airflow has greater tendency to become separated, with said vortex generator being positioned, relative to said lifting surface, to generate a vortex which travels rearwardly over, and adjacent to, said lifting surface ...
