NASA says it’ll give Boeing $425 million over the next seven years for the development and flight testing of a new breed of fuel-efficient airplane with ultra-thin wings.
The innovative airplane design could produce fuel savings of up to 30%, and blaze the trail for the aviation industry’s effort to reach net zero carbon emissions by 2050. “If we are successful, we may see these technologies in planes that the public takes to the skies in the 2030s,” NASA Administrator Bill Nelson said in a news release.
Boeing’s Transonic Truss-Based Wing concept, or TTBW, involves building an aircraft with extra-long, extra-thin wings that spread over the top of the fuselage. Extra stabilization would be provided by diagonal struts attached beneath the fuselage.
One configuration calls for foldable wings that are 170 feet wide — which is 27 feet shorter than the wingspan of a 787 Dreamliner but 53 feet wider than the wingspan of a 737 MAX 8.
