A low drag surface construction utilizes a plurality of longitudinally extending, parallel, spaced apart linear vortices extending transversely of the free stream to reduce drag between the free stream and the surface. The surface is provided with stabilizing means which retains the vortices in their relationship with one another but causes them to traverse the surface in the same direction as the free stream but at approximately half the speed. The stabilizing produces a regular variation in boundary flow across the surface and may comprise dynamic mean...
A surface construction subject to drag caused by a fluid stream thereacross having a plurality of linear vortices extending parallel with, and adjacent thereto, said surface construction comprising: vortex stabilizing means for producing a regularly spaced variation in boudnary flow streamwise of said surface construction to thereby stabilize the plurality of linear vortices in parallel spaced apart relationship to each other transverse of the boundary flow streamwise of the surface construction, said vortex stabilizing means including a plurality of ape...
