NASA's Sustainable Flight Demonstrator project completed wind tunnel testing of its X-66 semi-span model, marking a significant step towards developing more efficient and sustainable aircraft.
NASA 's Sustainable Flight Demonstrator (SFD) project recently wrapped up wind tunnel tests on its X-66 semi-span model in collaboration with Boeing . This model, designed to represent half the aircraft, allowed the research team to gather high-quality data about the aerodynamic forces that would affect the actual X-66 . The tests, conducted at NASA 's Ames Research Center in California's Silicon Valley, focused on simulating expected flight conditions.
Engineers installed pressure points, which are drilled holes with data sensors attached, along the wing's edge. These sensors provided insights into airflow characteristics, influencing the final wing design. Semi-span tests leverage the aircraft's symmetry, where the forces and behaviors on a half-model mirror those on the other half. By using a larger half-model, engineers increased the number of surface pressure measurements, allowing for a more comprehensive understanding of aerodynamic forces. Various sensors placed on the wing measured forces and movements to calculate lift, drag, stability, and other crucial characteristics.Data gathered from these tests, alongside those from smaller-scale tests conducted at NASA's Langley Research Center in Hampton, Virginia, will be meticulously studied. This analysis will inform any necessary design changes before the fabrication of the wing for the full-scale X-66 aircraft begins. The SFD project is NASA's initiative to develop more efficient aircraft configurations, paving the way for aviation that is economically, socially, and environmentally sustainable. It aims to provide valuable information for the next generation of single-aisle airliners, the most prevalent aircraft in commercial aviation fleets worldwide. Boeing and NASA are working together to develop the X-66 experimental demonstrator aircraft
