laminar flow control

[′lam·ə·nər ′flō kən‚trōl]
(aerospace engineering)
The removal of a small amount of boundary-layer air from the surface of an aircraft wing with the result that the airflow is laminar rather than turbulent; frictional drag is greatly reduced.

Even with metal wings, the techniques used for making the airliners now flying are effective enough to conserve laminar flow further back on the wing "if we just shave the rivets a thousandth of an inch or so," says Richard Wagner, head of NASA Langley's laminar flow control project.
With hybrid laminar flow control (HLFC), the boundary layer is stabilized by suction only at the leading edge of the wing, and smooth, contoured surfaces on the rest of the wing conserve that laminar airflow.
