The turbulent drag is reduced on the surface of a body moving through a fluid by providing longitudinal channels in the surface, for example of an aircraft wing, which channels extend in parallel to the flow direction and which channels are interconnected with the boundary layer by a longitudinal gap communicating the channel with the boundary layer.
An apparatus for reducing turbulent drag caused on a surface of a body by relative movement between said body and a fluid, said movement defining a given movement direction, comprising a surface zone in said body adjacent to said body surface in direct contact with said fluid, a plurality of longitudinal channels inside said surface zone, said channels extending in parallel to each other and in parallel to said given movement direction, each channel comprising a longitudinal gap in said body surface communicating the respective channel with a boundary la...
