Vicroy led the “free flight” experiment in the Langley Full Scale Tunnel’s huge 30-by-60-foot test section. But with this type of a flying wing design, we have fewer examples and less confidence in our flying quality estimates.” We know how to predict how they are going to fly. “We have a lot of experience with conventional airplanes. “When you get rid of the tail you have to come up with different ways to control the plane,” said Dan Vicroy, a senior research engineer at Langley. The blended wing body resembles a flying wing, unlike today’s “tube-and-wing” aircraft. One of the challenges to controlling a flying wing is determining how to blend the control surfaces to make the vehicle turn and climb. Those four are the rudder, the ailerons, the elevator and the flap. ![]() The five-percent scale model has 18 control surfaces along the trailing edges of the wing, compared to four on most airplanes. The model was tested in a wind tunnel to help engineers better understand how the blended wing body handles. This model will give visitors to the Smithsonian a glimpse into the future of air travel.” “Because of these technologies, airplanes may look very different 20 years from now. “One key focus of NASA aeronautics research is to develop technologies to make aircraft more fuel efficient and environmentally friendly,” said Jaiwon Shin, associate administrator for NASA’s Aeronautics Research Mission Directorate in Washington. The 12-foot wing span blended wing body, or BWB, model, used during wind tunnel flight tests at NASA’s Langley Research Center in Hampton, Va., is on long-term loan to the “How Things Fly” gallery at the Smithsonian Institution’s National Air and Space Museum in Washington. WASHINGTON – A flying model NASA built to research futuristic aircraft designs will spend its future in the United States’ premier air and space museum. ![]()
