To build the X-66A, Boeing will convert an MD-90 into a full-scale demonstrator aircraft with extra-long, thin wings stabilized by diagonal struts, or trusses.īig picture: The SFD program is one key way that Boeing believes it will help achieve commercial aviation’s goal of net zero emission by 2050, in addition to renewable energy transition, operational efficiency and fleet renewal.Unofficial X-Plane enthusiast sub.

X-planes are intended to test designs and technologies that can be adopted into other aircraft designs, not serve as prototypes for full production.Ĭatch up quick: For more than a decade, Boeing and NASA have been studying the TTBW concept as part of the Subsonic Ultra Green Aircraft Research (SUGAR) program.aircraft and rockets designed to test and evaluate new technologies and aerodynamic concepts. What’s an X-plane? These are experimental U.S. NASA Administrator Bill Nelson (center) tours the 737 factory with (from left) Todd Citron, chief technology officer Mike Sinnett, vice president and general manager, Commercial Product Development and Ed Clark, vice president and general manager, 737 program. “This aircraft can be a leader in advancing numerous technologies while helping to decarbonize aerospace.” “The X-66A concept is the product of years of homework done in conjunction with NASA,” Citron said.“NASA and Boeing are taking sustainable aerospace technology to new heights, while humanity and the environment see tremendous benefits.” “The X-66A shows a lot of promise,” Nelson said.achieve the goal of net-zero aviation greenhouse gas emissions. This is the first X-plane specifically focused on helping the U.S.The transonic truss-braced wing (TTBW) design, when combined with other advancements in propulsion systems, materials, and systems architecture, could achieve up to a 30% reduction in fuel consumption and emissions.Why it matters: The technologies demonstrated and tested on the X-66A as part of the SFD program will inform future designs and could lead to groundbreaking aerodynamics and fuel efficiency. The transonic truss-braced wing design, when combined with other advancements in propulsion systems, materials, and systems architecture, could achieve up to a 30% reduction in fuel consumption and emissions.
