    The transonic truss-braced wing demonstrator will actually have rear-mounted engines. A retired MD-90 will have its wings removed, to be replaced by a prototype high wing and truss configuration. First flight is 2029-ish.

    Boeing PR release:

    Boeing Awarded NASA Sustainable Flight Demonstrator Contract

    - NASA, Boeing and partners aim to cut fuel use and emissions up to 30% in single-aisle airplanes

    - Advances in sustainable technology are crucial to reaching civil aviation's goal to be net zero carbon emissions by 2050

    ARLINGTON, Va
    Jan. 18, 2023

    NASA has selected Boeing [NYSE: BA] and its industry team to lead the development and flight testing of a full-scale Transonic Truss-Braced Wing (TTBW) demonstrator airplane.

    The technologies demonstrated and tested as part of the Sustainable Flight Demonstrator (SFD) program will inform future designs and could lead to breakthrough aerodynamics and fuel efficiency gains.

    When combined with expected advancements in propulsion systems, materials and systems architecture, a single-aisle airplane with a TTBW configuration could reduce fuel consumption and emissions up to 30% relative to today's most efficient single-aisle airplanes, depending on the mission. The SFD program aims to advance the civil aviation industry's commitment to reaching net zero carbon emissions by 2050, as well as the goals set forth in the White House's U.S. Aviation Climate Action Plan.

    "The SFD program has the potential to make a major contribution toward a sustainable future," said Greg Hyslop, Boeing chief engineer and executive vice president of Engineering, Test & Technology. "It represents an opportunity to design, build and fly a full-scale experimental plane, while solving novel technical problems."

    Ultrathin wings braced by struts with larger spans and higher-aspect ratios could eventually accommodate advanced propulsion systems that are limited by a lack of underwing space in today's low-wing airplane configurations. For the demonstrator vehicle, Boeing will use elements from existing vehicles and integrate them with all-new components.

    NASA's funding through the SFD Space Act Agreement totals $425 million. The SFD program will also leverage up to $725 million in funding by Boeing and its industry partners to shape the demonstrator program and meet the resource needs required. Separately, Boeing's previous internal investments for recent phases of sustainable aviation research total $110 million.

    The TTBW airframe concept is the result of more than a decade of development supported by NASA, Boeing and industry investments. Under previous NASA programs including the agency's Subsonic Ultra Green Aircraft Research program, Boeing conducted extensive wind tunnel testing and digital modeling to advance the design of the TTBW. Early conceptual studies started under NASA's Environmentally Responsible Aviation program.

          Can we just restart the 757 production line?

            Wrong. Russia make even better airplane. Carry 2000 people, burn CO2 and exhaust Oxygen.

              It's a special airplane operation.
