Greener commercial flight technology may be on the horizon.

NASA and Boeing will collaborate on a sustainable flight demonstrator project to build, test and fly a single-aisle aircraft that will reduce emissions over the next decade, NASA announced Wednesday.

“From the beginning, NASA has been with you when you fly. NASA dared to go farther, faster and higher. It’s in our DNA,” said NASA Administrator Bill Nelson in a statement.

“Our goal is for NASA to work with Boeing to build and test a full-scale demonstrator, a future that is more fuel efficient and benefits the environment, the commercial aviation industry and passengers around the world. If we are successful, these technologies could be on board the planes that will fly the masses in the 2030s.”

The first test flight of this experimental aircraft is set Nelson said the goal is to bring the technology to about 50% of the commercial market through short- to medium-haul single-aisle aircraft.

According to NASA, airlines rely primarily on single-aisle aircraft, which account for almost half of global aviation emissions. The development of new technologies to reduce fuel use will support the Biden administration’s goal of net zero carbon emissions from aviation by 2050, as set out in the U.S. Aviation Climate Action Plan. I can.

Boeing expects demand for new single-aisle aircraft to grow by 40,000 between 2035 and 2050.

NASA Administrator Bill Nelson has a model aircraft with a Transonic truss braced wing.

NASA and Boeing are working on designs that could reduce fuel consumption and emissions by up to 30% compared to today’s most efficient aircraft.

Called the Transonic Truss-Braced Wing concept, it relies on an elongated wing stabilized by diagonal struts that connect the wing to the aircraft. The shape of the design reduces drag. This means less fuel is burned.

The sustainable flight demonstrator will also incorporate other green aviation technologies.

“NASA has the ambition to develop breakthrough technologies to reduce aviation energy use and emissions over the next few decades, towards the aviation community’s goal of net zero carbon emissions by 2050. “We are working toward our ambitious goals,” said the Directorate General of Research Missions in a statement.

“The Transonic Truss-Braced Wing is the innovative concept and investment needed to meet these challenges, and importantly, the technology demonstrated in this project will power the next generation of single-aisle aircraft. We have a clear and workable path to providing everyone who uses the air transportation system.”

The benefits of increasing the wing aspect ratio have long been known, but the challenges of building the design required advances in materials and construction to reach this development point.

Partnering on this project allows NASA and Boeing to take more risks than the airline industry. Unique, he said.

“This is an experimental aircraft,” he said. “This is not a commercial development of the aircraft that passengers fly today.

The partnership, which is supported by the Funded Space Act Agreement, will rely on technical expertise and facilities, as well as $425 million over seven years from NASA. Meanwhile, Boeing and its partners will contribute the rest of his $725 million and technology plans.

“We are honored to continue our partnership with NASA to demonstrate technology that significantly improves aerodynamic efficiency and significantly reduces fuel burn and emissions,” said Boeing Chief Technology Officer Todd Citron. think.
