Aviation: Boeing and Nasa want to build fuel

2023-01-19T06:40:43.271Z


The goal is up to 30 percent fewer emissions than the most environmentally friendly current models: The aircraft manufacturer Boeing is building a test machine with unusual wings on behalf of NASA.

The US space agency Nasa has awarded a consortium led by the aviation group Boeing the contract to build and test a particularly low-emission aircraft.

If successful, the new type of aircraft could be used by airlines in the 1930s, said Nasa boss Bill Nelson when announcing the cooperation in Washington.

NASA says it will invest $425 million in the project over the next seven years, and Boeing and its partners will invest another $725 million.

In addition, the authority wants to support the consortium with know-how and the use of its facilities.

The program should be completed by the end of the decade.

The test aircraft – the project name is “Sustainable Flight Demonstrator” (SFD) – is to have a special wing construction: so-called transonic truss-braced wings (TTBW), i.e. particularly long wings that are stabilized by diagonal struts.

This design enables significantly less drag than a conventional commercial aircraft and can thus reduce fuel consumption accordingly, NASA said.

The basis of the demonstration aircraft should be a so-called single-aisle machine, i.e. an aircraft with a narrow fuselage and a central aisle in the cabin, such as the airlines mostly have in their fleets.

The goal is to reduce fuel consumption by up to 30 percent compared to today's most efficient machine types.

According to the statement by the US space agency, this should not only be achieved through the innovative wing design, but also through further developed drive systems and materials.

The aviation industry has set itself the goal of reducing its CO2 emissions to zero by 2050.
