The National Aeronautics and Space Administration (NASA) and Arlington, Va.’s Boeing said the aircraft produced through the agency’s Sustainable Flight Demonstrator project has been designated by the U.S. Air Force as the X-66A.
The new X-plane seeks to inform a potential new generation of more sustainable single-aisle aircraft – the workhorse of passenger airlines around the world. Working with NASA, Boeing will build, test, and fly a full-scale demonstrator aircraft with extra-long, thin wings stabilized by diagonal struts, known as a Transonic Truss-Braced Wing concept.
The X-66A is the first X-plane specifically focused on helping the United States achieve the goal of net-zero aviation greenhouse gas emissions, which was articulated in the White House’s U.S. Aviation Climate Action Plan.
