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

NASA test pilots Jim Less, left, and Nils Larson walk away from a hangar at NASA’s Armstrong Flight Research Center in Edwards, California, on Thursday, Feb. 4, 2026. The pilots support 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.
