ALEXANDRIA, Va., Dec. 9 -- United States Patent no. 12,492,717, issued on Dec. 9.

"Device to reduce turbulent flow skin friction using carbon dioxide, riblets, and suction holes" was invented by Papa Abdoulaye Mbodj (Denver).

According to the abstract* released by the U.S. Patent & Trademark Office: "A device to reduce turbulent flow skin friction uses carbon dioxide, riblets, and suction holes to reduce the overall drag of a body moving in a fluid. A deflector (2) pushes up the boundary layer of the incoming flow on a surface (1). Carbon dioxide is injected into a plenum (3) and ejected through an exhaust slot (4).
