Bracing for Fuel-Efficient Flight NASA
WebApr 19, 2024 · The TTBW is essentially a classic tube-and-wing passenger aircraft whose wings are extremely long and thin – so much that they need a little help to hold them up. By narrowing the thickness of the wings and extending their length, drag is reduced, and 5-10% less fuel is burned than comparable narrowbody aircraft. WebJun 9, 2024 · NASA plans to solicit industry in early 2024 for preliminary designs of aircraft configurations that could be tested, with the potential for first flight of the demonstrator no earlier than late 2026.
