NASA has successfully completed the first flight test of its innovative Crossflow Attenuated Natural Laminar Flow (CATNLF) scale-model wing, designed to enhance laminar flow and decrease drag, ultimately lowering fuel costs for commercial aircraft. This historic flight took place on January 29 at NASA’s Armstrong Flight Research Center in Edwards, California, utilizing one of the agency’s F-15B research jets.
The CATNLF wing model, measuring approximately 40 inches and mounted vertically like a fin beneath the aircraft, successfully completed a 75-minute flight. During this time, the research team confirmed that the aircraft could maneuver safely with the additional wing model attached. “It was incredible to see CATNLF fly after all of the hard work the team has put into preparing,” stated Michelle Banchy, the research principal investigator for CATNLF.
Flight Objectives and Maneuvers
The primary objective of this initial flight was to expand the operational envelope of the CATNLF design. The team performed various maneuvers, including turns, steady holds, and gentle pitch changes, at altitudes ranging from approximately 20,000 to nearly 34,000 feet. These maneuvers provided crucial insights into the aerodynamic characteristics of the wing model, confirming that it operates as anticipated.
Data Collection and Future Tests
To assess the effectiveness of the CATNLF design in maintaining smooth airflow, the team employed several measurement tools, including an infrared camera mounted on the aircraft. This camera collected thermal data during the flight tests, which will be analyzed to validate key aspects of the design. Early results indicated that the airflow over the aircraft closely matched predictions made through computer modeling.
This flight marks the beginning of a series of tests, with up to 15 additional flights planned to evaluate the CATNLF design under various speeds, altitudes, and flight conditions. “First flight was primarily focused on envelope expansion,” Banchy explained, emphasizing the need to ensure safe dynamic behavior before proceeding to more complex research maneuvers.
Implications for Future Aircraft Design
The CATNLF technology aims to improve laminar flow over swept-back wings, which are commonly used in both airliners and fighter jets. By minimizing disruptions that lead to drag, this technology has the potential to significantly reduce fuel consumption. The ongoing tests will further validate the CATNLF model and its implications for future aircraft designs, contributing to NASA’s broader aeronautics research efforts.
The CATNLF testing is part of a collaborative initiative under NASA’s Flight Demonstrations and Capabilities project and the Subsonic Vehicle Technologies and Tools project, supported by the agency’s Aeronautics Research Mission Directorate.
