DBT Aero (Riverton, UT) says its unconventional aircraft geometry could cut fuel burn, boost payload, and revive regional aviation economics. Founder Michael Duke is bringing that argument to the 47G Summit with a vision for flight.
Riverton, Utah — May 20, 2026
This article is part of series of interviews TechBuzz has conducted with companies participating in the upcoming Project Alta Summit, hosted by 47G on May 26–27 at the Ken Garff University Club at Rice-Eccles Stadium in Salt Lake City. The two-day event will convene nearly 200 companies at the forefront of advanced air mobility, bringing together manufacturers, infrastructure partners, regulators, and policymakers at what many in the industry are calling a critical inflection point for AAM deployment.
As Utah’s aerospace community gathers for 47G's Project Alta Summit, one of the more intriguing aircraft companies on the horizon is not simply promising cleaner propulsion or another incremental airframe upgrade. Riverton, Utah-based DBT Aero is asking a more fundamental question: what if the airplane itself has been optimized around the wrong shape?
Founder and CEO Michael A. Duke believes the answer lies in rethinking the relationship between wing, tail, structure, and propulsion. The result is an aircraft design that looks unconventional at first glance, especially in the tail, but which Duke says is rooted less in novelty than in integration. In his telling, DBT Aero’s striking silhouette is not a stylistic exercise. It is what happens when aerodynamic efficiency becomes the driver and legacy assumptions stop calling the shots.
“The design was the outcome,” Duke said during a recent conversation with TechBuzz. “We’ve taken five or six proven aerodynamic principles studied by NASA and others and integrated them together. And they’ve never been integrated.”
That distinction matters. Aviation startups often lead with futuristic imagery. Duke, by contrast, repeatedly returned to engineering tradeoffs, structural stiffness, manufacturability, operating costs, and certification. He also spoke like someone who knows that in aviation, technical elegance is never enough. If the economics do not work, the airplane does not matter.
Still, it is the shape that first grabs attention.
DBT Aero’s aircraft features what Duke describes as a tail unlike anything now flying in mainstream service. He explains it in plain language: imagine a T-tail cut down the middle, then slide the two halves outward until they connect with the winglets, forming a box-like structure. Some observers may think of that as a box wing, but Duke argues it is something more specific — a joined relationship between tail and wing that behaves differently aerodynamically because the upper surface is still functioning as a tail, producing downward force rather than lift.
“By combining a tail with a wing, we actually end up with very different aerodynamics that nobody else in the world is using,” Duke said.
According to Duke, the benefits are both aerodynamic and structural. The joined geometry creates a stiffer airframe, which he says can reduce flex, improve stability, and allow the aircraft to use less material while remaining stronger. Visitors who come to see the aircraft, he said, are often startled by how robust it feels. Traditional airplanes train people to step carefully and avoid most of the wing. DBT Aero’s prototype, he said, inspires a different reaction only after people are reassured they are not about to damage it.
“It’s a whole new vision of what a plane is,” Duke said.
The company’s argument extends beyond the tail. Duke says DBT Aero’s design also incorporates natural laminar flow thinking, a pusher propulsion configuration, compact wings with what he describes as effectively longer aerodynamic performance, and hybrid-electric architecture for larger aircraft concepts. The goal is not merely to make a plane look different. The goal is to create an aircraft that is, in Duke’s words, “slippery” — lighter, quieter, faster, and more efficient than conventional designs in the same class.
One of the more interesting parts of Duke’s explanation is his focus on propulsion placement. DBT Aero uses a pusher configuration rather than the more traditional tractor arrangement with the propeller in front. Duke says that choice improves efficiency when executed properly and also helps maintain cleaner airflow over the fuselage.
“The thing that stands out is the double box tail,” he said. “But if you look at our propulsion, we actually have a pusher configuration, not the traditional tractor. That is by design.”
According to Duke, pulling air over the fuselage in that configuration can help preserve laminar flow longer and reduce turbulence, which in turn makes the cabin quieter. For a company talking about efficiency, the emphasis is notable: not just propulsion innovation, but airframe-propulsion integration.
DBT Aero has also built several smaller unmanned demonstrators, including RC-scale aircraft, as part of its development process.
Duke also says DBT Aero’s patents center on stability and control, and he described handling characteristics that, if borne out in certification and production, would be significant. He said the company flew a version of the aircraft without rudders and “it turned perfectly well,” attributing that behavior to the way the control forces work through the tail rather than by changing wing camber in the conventional way. He also said the aircraft does not exhibit the same spin tendencies as many conventional designs. Those are substantial claims, and as with all early-stage aerospace programs, they will ultimately be judged through continued testing, regulatory scrutiny, and operational use.
Perhaps the sharpest insight from Duke had less to do with fluid dynamics than with industrial inertia. Asked why aviation has not already embraced more radical geometries, Duke did not blame a lack of imagination. He blamed installed systems.
“Do you really want to go out and cannibalize your own product line with something that’s radically different?” he said. “Generally, no.”
That may be the cleanest explanation for why aviation, despite its aura of innovation, often moves cautiously on airframe design. Large manufacturers have decades of tooling, engineering workflows, training, supply chains, and customer expectations wrapped around familiar forms. They tend to iterate rather than start over. Startups, if they are going to matter, need to exploit that conservatism rather than imitate it.
DBT Aero does not plan to be a licensing house waiting for incumbents to notice. Duke says the company wants to become an original equipment manufacturer in its own right — “another Piper, Textron, Embraer, Boeing, Airbus,” as he put it — beginning with a small general aviation aircraft and then moving up the market.
The first commercial target is a two-seat aircraft designed for the FAA’s new MOSAIC-era certification framework. According to Duke, DBT Aero’s target is a cruise speed above 200 knots while burning roughly eight to nine gallons per hour, with a range of more than 1,000 nautical miles. He says that would make the aircraft faster, more efficient, and less expensive to operate than comparably missioned conventional aircraft. Those numbers, if achieved in production, would be eye-catching in general aviation, especially for owner-pilots who travel long distances and care about both time and operating cost.
The larger strategic play may be even more compelling. Duke says DBT Aero’s second major aircraft concept is a utility plane in the size class of a Cessna Caravan or Daher Kodiak — roughly nine passengers plus cargo. According to DBT Aero, aerodynamic efficiency in that class could allow a smaller propulsion system, less fuel burn, and more payload.
“We can carry about 50 percent more useful load in the same wingspan aircraft and burn one third of the fuel,” Duke said, comparing DBT Aero’s concept with existing aircraft in that category.
Again, those are company claims, not independently validated performance figures. But they point to the economic story Duke most wants investors and operators to understand. This, he insists, is not mainly about futuristic aesthetics. It is about math.
“What really makes the difference is when you get the accountants in the room and they start pushing the spreadsheets and sharpening their pencils,” he said.
For Duke, that same practical mindset shapes DBT Aero’s propulsion strategy. While much of advanced air mobility continues to orbit around battery limitations and all-electric aspirations, DBT Aero is pursuing a hybrid-electric path for larger aircraft. Duke, a former fixed-base operator owner, says he has little patience for propulsion concepts that ignore real-world airport operations.
“You need to be able to service people and get them on their way,” he said. “You don’t jump straight to a new technology until the technology is ready for prime time.”
According to Duke, DBT Aero’s larger aircraft concept uses a hybrid-electric ducted fan system: fuel powers a generator, the generator produces electricity, and that electricity drives the fan. He argues that architecture can preserve the practical advantages of rapid refueling while reducing noise, simplifying some maintenance demands, and lowering fuel use because the airframe itself needs less power.
The company’s credibility also rests on progress with regulators. DBT Aero has received an FAA experimental research and development airworthiness certificate for its manned proof-of-concept aircraft, and Duke says the company has maintained a constructive relationship with the agency since around 2020. He also serves on the ASTM F37 committee connected to the MOSAIC rulemaking framework, giving him a close view of the standards that will shape the company’s entry into the market.
Duke even shared an anecdote that captures both the novelty of the design and the seriousness with which he believes it is being received. When DBT Aero received its experimental airworthiness certificate, he said, FAA officials quietly told the company: “This is really cool. Would you please hurry up and move to certification?”
For Utah, DBT Aero carries an additional layer of interest. The company is a Delaware C-corp headquartered in Utah, with a 12-person distributed team spread across the U.S. and abroad. Duke says Utah is an ideal place to build because of the state’s deep aerospace supply chain, composite manufacturing base, and links to programs such as the F-35. He specifically pointed to local expertise in carbon fiber composites and said DBT Aero’s airframe is particularly well suited to that kind of construction.
“There isn’t what I would call a soup-to-nuts OEM yet,” Duke said. “And that’s kind of our goal. We are looking to become kind of that first Utah aviation OEM.”
That ambition is large, and the road ahead remains difficult. Aerospace history is littered with elegant ideas that never survived certification, manufacturing scale, or capital intensity. DBT Aero still has to prove that its performance claims translate from prototype and modeling into certifiable, repeatable aircraft. It has to show that unconventional geometry can become a dependable business, not just an interesting engineering conversation.
But that is also what makes Duke and DBT Aero worth watching as 47G opens. In a sector crowded with battery promises and concept art, Duke is making an argument that feels both older and more disruptive: if flight is going to become more efficient, more sustainable, and more economically resilient, the answer may begin not with the fuel tank or the battery pack, but with the shape of the airplane itself.
And if DBT Aero is right, Utah may one day be known not just for supporting aerospace innovation, but for helping build a very different kind of aircraft company from the ground up.
