A VORTEX CONTROLLER FOR REDUCING DRAG IMPARTED ON AN AIRCRAFT AFTERBODY FUSELAGE

摘要

A method and apparatus of creating vortices via vortex controllers (10), wherein the vortices (30) are capable of entraining high-energy surrounding flow to induce a series of powerful longitudinal vortices that reattach separated flow by merging into single vortices along the undersurface of the afterbody (102) to reenergize the boundary layer, thus preventing undersurface flow separation and reducing overall afterbody drag.
