Description
Summary:Hariharan focuses on the testing designs to increase aircraft fuel efficiency. A new NASA design method, referred to as Crossflow Attenuated Natural Laminar Flow, was model-tested in June in the National Transonic Facility, a high-pressure, cryogenic wind tunnel at NASA's Langley Research Center in Virginia. CATNLF carefully designs the leading-edge shape of the wing to enable natural laminar flow on typical transport wings with high sweep and Reynolds numbers. Laminar flow has been studied for decades because of its promise for reducing fuel burn via decreased aircraft drag.
