Downwash in aerodynamics
WebWhen a wing generates aerodynamic lift, it results in a region of downwash between the two vortices.: 8.1.1 Three-dimensional lift and the occurrence of wingtip vortices can be approached with the concept of horseshoe vortex and described accurately with the Lanchester–Prandtl theory.In this view, the trailing vortex is a continuation of the wing … http://www.ockam.com/2013/03/12/measuring-wind-direction-what-is-upwash/
