Get ready for another prototype airplane that looks as if it flew straight out of a science-fiction novel.

The Department of the Air Force has selected JetZero’s design for a prototype aircraft that has a swoopy blended wing body, or BWB, rather than the typical tube-and-wing look.

The design has the potential to decrease aerodynamic drag by at least 30% and provide additional lift. This could translate into extended range, more loiter time and increased payload delivery efficiencies for the Air Force.

“Blended wing body aircraft have the potential to significantly reduce fuel demand and increase global reach,” Air Force Secretary Frank Kendall said in a news release. “Moving forces and cargo quickly, efficiently, and over long distance is a critical capability to enable national security strategy.”

Commercial aviation could benefit as well. “The BWB is the best first step on the path to zero carbon emissions,” JetZero CEO Tom O’Leary said in a news release. “It offers 50% lower fuel burn using today’s engines, and the airframe efficiency needed to support a transition to zero carbon emissions propulsion in the future. No other proposed aircraft comes close in terms of efficiency.”

Airlines join Boeing’s team to work on eco-friendly plane

Planned livery for X-66A airplane
X-66A Transonic Truss-Braced Wing aircraft

Boeing and NASA say they’ll collaborate with Seattle-based Alaska Airlines and four other major airlines on the Sustainable Flight Demonstrator project, which aims to put Boeing’s innovative X-66 braced-wing aircraft design through flight tests in the 2028-2029 time frame.

The X-66A makes use of a concept known as the Transonic Truss-Braced Wing, or TTBW, which features ultra-long, ultra-thin, drag-reducing wings that are stabilized by diagonal struts.

The demonstrator aircraft will also incorporate parallel advancements in propulsion systems, materials and system architecture. When all those factors are combined, the single-aisle X-66A should reduce fuel requirements and carbon emissions by up to 30% relative to today’s domestic airplane fleet.

California-based Stratolaunch, the venture created by the late Microsoft co-founder Paul Allen, released a separation test vehicle for the first time this weekend during an experimental flight of the world’s largest airplane.

The event marked a significant milestone in Stratolaunch’s quest to create an air-launch system for rocket-powered hypersonic vehicles.

The May 13 outing was the 11th flight test for Stratolaunch’s flying launch pad — a twin-fuselage, six-engine airplane with a record-setting 385-foot wingspan. The plane is nicknamed Roc in honor of a giant bird in Middle East mythology.

Roc carried the Talon-A separation test vehicle, known as TA-0, during three previous test flights. But this was the first time TA-0 was released from Roc’s center-wing pylon to fly free. The release took place during a four-hour, eight-minute flight that involved operations in Vandenberg Space Force Base’s Western Range, off California’s central coast.

NASA says it’ll give Boeing $425 million over the next seven years for the development and flight testing of a new breed of fuel-efficient airplane with ultra-thin wings.

The innovative airplane design could produce fuel savings of up to 30%, and blaze the trail for the aviation industry’s effort to reach net zero carbon emissions by 2050. “If we are successful, we may see these technologies in planes that the public takes to the skies in the 2030s,” NASA Administrator Bill Nelson said in a news release.

Boeing’s Transonic Truss-Based Wing concept, or TTBW, involves building an aircraft with extra-long, extra-thin wings that spread over the top of the fuselage. Extra stabilization would be provided by diagonal struts attached beneath the fuselage.

One configuration calls for foldable wings that are 170 feet wide — which is 27 feet shorter than the wingspan of a 787 Dreamliner but 53 feet wider than the wingspan of a 737 MAX 8.

Stratolaunch, the air-launch company founded by the late Seattle software billionaire Paul Allen, today conducted its second captive-carry test flight with the world’s largest airplane and a piggyback payload. The six-hour outing from California’s Mojave Air and Space Port marked further progress toward the first launch of the Talon-A hypersonic flight vehicle.

Today’s flight gave Stratolaunch’s team a chance to rehearse procedures for releasing a separation test vehicle from the twin-fuselage Roc aircraft in midflight — and eventually launching rocket-powered Talon-A vehicles for government and commercial applications. “We are excited for what’s ahead this year as we bring out hypersonic flight test service online for our customers and the nation,” Stratolaunch CEO Zachary Krevor said in a news release.

A few years from now, we just might look back at 2022 as Year One for a new age in aerospace: It was the year when NASA’s next-generation space telescope delivered the goods, when NASA’s moon rocket aced its first flight test, and when an all-electric passenger plane built from the ground up took to the skies.

I’ve been rounding up the top stories in space on an annual basis for 25 years now (starting with the Mars Pathfinder mission in 1997), and 2022 ranks among the biggest years when it comes to opening up new frontiers on the final frontier. The best thing about these frontier-opening stories — especially the James Webb Space Telescope and the Artemis moon program — is that the best is yet to come.

Check out my top-five list for the big stories of the past year, plus five aerospace trends to watch in the year ahead.

Virgin Galactic says it will partner with Aurora Flight Sciences, a Virginia-based Boeing subsidiary, to design and build next-generation motherships for its suborbital rocket planes.

The motherships will serve as flying launch pads for Virgin Galactic’s next-gen, Delta-class spacecraft, just as a carrier airplane called White Knight Two or VMS Eve has served for the company’s SpaceShipTwo VSS Unity rocket plane.

The system’s design is an upgraded version of the SpaceShipOne system that was funded almost two decades ago by Paul Allen, the late Microsoft co-founder, and won the $10 million Ansari X Prize in 2004.

VSS Unity and VMS Eve have been undergoing test flights for years, and commercial suborbital space missions are scheduled to begin next year at Spaceport America in New Mexico. Hundreds of customers have reserved spots on future flights.

The next-generation mothership and rocket plane are due to start revenue-generating missions in 2025. The partnership announced today will cover the production of two motherships.

Stratolaunch says its mammoth carrier airplane rose to its highest altitude yet during its seventh flight test over California’s Mojave Desert.

The aerospace venture, which was established by Microsoft co-founder Paul Allen more than a decade ago but is now owned by a private equity firm, reported a peak altitude of 27,000 feet during today’s test.

If all goes according to plan, the twin-fuselage Roc airplane could begin flying Stratolaunch’s Talon-A hypersonic test vehicles for captive-carry and separation testing as early as this year.

One of the prime objectives for today’s three-hour flight at the Mojave Air and Space Port was to gather data on the aerodynamic characteristics of the plane, including a pylon structure from which the rocket-powered Talon-A vehicles will be released and launched.

Roc’s seventh flight came a week after the sixth flight test, which couldn’t achieve all of its objectives.

More than two decades after the Boeing Co. moved its headquarters from its Seattle birthplace to Chicago, the aerospace giant is planning to do it again — this time, heading for Arlington, Va.

Boeing confirmed a report about the move that appeared today in The Wall Street Journal. Arlington already serves as the headquarters for Boeing’s defense, space and security business unit, and the company said it would develop a new research and technology hub in Northern Virginia.

“We are excited to build on our foundation here in Northern Virginia,” Boeing’s president and CEO, Dave Calhoun, said in a news release. “The region makes strategic sense for our global headquarters given its proximity to our customers and stakeholders, and its access to world-class engineering and technical talent.”

Boeing didn’t provide a timetable for the HQ switchover.

The move to Arlington in the Washington, D.C., area reflects a classic corporate strategy to have the company’s executive offices close to where the federal government’s purchasing decisions are made.
