Boeing gets NASA contract to develop new airplane wing design
In its effort to reduce fossil fuel use and thus save us from being burned to death by global warming in only a decade, NASA has now awarded Boeing a contract to develop new airplane wing design that it predicts will lower fuel use by up to 30%.
The X-66A is the X-plane specifically aimed at helping the United States achieve the goal of net-zero greenhouse gas emissions by 2050. To build the X-66A, Boeing will work with NASA to modify an MD-90 aircraft, shortening the fuselage and replacing its wings and engines. The resulting demonstrator aircraft will have long, thin wings with engines mounted underneath and a set of aerodynamic trusses for support. The design, which Boeing submitted for NASA’s Sustainable Flight Demonstrator project, is known as a Transonic Truss-Braced Wing.
While developing a more efficient wing design is certainly worthwhile, having skepticism about this project is certainly reasonable. First of all, it seems somewhat strange to award Boeing such a contract at this time, considering NASA own experience with the company with Starliner, as well as that company’s problems with other government contracts for the military.
Secondly, the press release makes a big deal about the project getting an X-plane designation, an entirely superficial and PR related title that if anything suggests there is very little steak to this sizzle.
Third, it is unclear the nature of this contract. Is is cost-plus, or fixed price? The press release says NASA will “invest $425 million over seven years, while the company and its partners will contribute the remainder of the funding, estimated at about $725 million.” If cost-plus, this means nothing. Boeing will use any excuse to go over budget in order to get more money from NASA.
Finally, half a billion dollars to develop and test a new airplane wing design, using an already existing airplane, seems incredibly exorbitant. And to require seven years to build it seems ridiculously long.
All in all, I suspect the real goal of this project is to funnel tax dollars to Boeing to help keep it afloat, not to build a new green airplane.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.

“The resulting demonstrator aircraft will have long, thin wings” Gee, That gets us to where Consolidated was in the late Thirties with the Davis Wing. https://handwiki.org/wiki/Engineering:Davis_wing#/media/File:Consolidated_B-24_Liberator_from_above.jpg. “and a set of aerodynamic trusses for support.” Just like the Wright Brothers a century and a half ago. Elimination of such trusses was a major aeronautical advance….In the 1930’s. The P-26 “Peashooter” was the last USAAF fighter with such bracing
This idea makes me think that maybe the FAA should try to keep a better eye on Boeing than they did with the 737 MAX, rather than hobbling SpaceX! And that Boeing had better hope that Elon doesn’t take an interest in airplanes!
The Peashooter was a Boeing creation, by the way! Yuck.
The article mentions that the 30% efficiency increase is not just the wing but also improvements of engines, materials, and cetera.
This video is by a pilot who reviews and comments on these kinds of things, and this one is on the topic of the transonic truss-braced wing. He goes into background, details, and information that is outside the scope of a press release:

Note that he says that the wing gives an improved efficiency of 9 to 10%, and the 30% overall improvement is in addition to the improvements gained in the 737-800 design.
Edward: Seems to me that Boeing should be paying for these refinements, not the American taxpayer.
Well, the libertarian Old Space bashers want NASA to be more like NACA—and they did support airplanes at some level.
But Boeing is primarily a plane company—and they should indeed foot this bil.
It is good that trusses are making a comeback for larger designs.
The flying Boat guys thought they could give the US cheaper force projection than carriers.
Rickover stomped them flat.
Long before Musk, Phil Bono and the Alabama-based ABMA talked troop rockets.
USAF stomped that behind the scenes.
LeMay and Rickover ruled the roost here.
Korolev and Glushko in the USSR.
Space advocates have always ranked below the janitor at the Pentagon
