NASA engineers have tested a new laminar-flow wing concept at the Armstrong Flight Research Center by mounting a scaled CATNLF model beneath an F-15B aircraft. During high-speed taxi trials reaching about 144 mph, the design demonstrated potential to keep airflow smooth longer, reducing drag. NASA estimates the technology could cut fuel consumption by up to 10% on large airliners, offering major cost savings and lower emissions for future commercial aviation. Real-world flight tests are expected to begin soon, worldwide adoption.
