NASA’s Crossflow Attenuated Natural Laminar Flow (CATNLF) Project Tests Model Wing on F-15

Four NASA employees walk toward a hangar after a flight Thursday, Feb. 4, 2026, at NASA’s Armstrong Flight Research Center in Edwards, California. The team supports the agency’s Crossflow Attenuated Natural Laminar Flow (CATNLF) project, which aims to lower fuel costs for future commercial aircraft by testing a scale-model wing designed to improve laminar flow.
