Eenuee Aerospace: Blended-Wing Electric Seaplanes Redefining Regional Aviation Sustainability
An exploration of how blended-wing design, electric propulsion, and amphibious capability are being combined to create a next-generation regional aircraft aimed at radically reducing aviation’s carbon footprint.
Imagine boarding an aircraft that looks more like a sleek sail than a traditional tube-and-wing design—one that can seamlessly land on both runways and water, and reduce its carbon footprint by nearly 30% (according to the latest Full Life Cycle Analysis compared to usual dual thermal engine 19-seater, such as DHC Twin Otter or Cessna SkyCourier) without a single drop of fossil fuel burned.
EcoAero had the opportunity to sit down with Gaspar Loury, a prototypist and workshop manager at Eenuee, to learn how this compact startup is redefining regional aviation through disruptive design, advanced materials, and a fresh approach to sustainability.
At just 28 years old, Gaspar brings hands-on expertise to Eenuee’s small but dynamic team. With a background in materials engineering and a specialization in carbon-fiber composites, he honed his workshop skills building kite-foil boards and racing cars from scratch. Today, everything that happens in Eenuee’s workshop—from shaping composite skins to assembling scale models—passes through his hands. Gasper also works very closely with Hugo Aveddo, the company’s fluid dynamic engineer. According to Gasper “he’s the brains and I'm the hands as we try to work in parallel as much as possible,” most of Hugo’s simulation and CFD works are validated with a physical demonstrator and most of Gasper’s workshop creations are then validated through his softwares.
Rather than chasing the uncharted waters of urban air mobility or vertical takeoff, Eenuee is focusing on a proven regulatory framework: a 19-passenger blended-wing-body (BWB) aircraft certified under CS-23/FAR-23 rules. This approach accelerates market entry by working within existing safety domains, while delivering up to a 96% reduction in lifecycle carbon emissions purely through aerodynamic efficiency. With a lift-to-drag ratio around 27—comparable to high performance gliders—the aircraft is engineered for maximum range on battery power alone, using solid state cells soon to be produced locally in France.
Building on patented technology developed by the team for light-sport seaplanes, Eenuee’s design employs regular landing gear coupled with retractable hydrofoils that allows waterborne operations without sacrificing performance on land. Beyond passenger transport, this versatility unlocks applications such as airborne surgery, organ transport, and disaster relief—missions that demand door-to-door access in remote regions of Canada, Scandinavia, and Southeast Asia.
While aerodynamic efficiency remains the technical priority, Gaspar emphasizes that funding and partnerships are equally crucial. Eenuee is collaborating with regional laboratories, small-scale suppliers, and larger industrial actors to co-develop recyclable composite skins and lightweight structures. These demonstrators not only validate new materials but also galvanize local innovation ecosystems.
“It's really different. So we are developing an airplane itself, a new envelope. You've seen it. It's a BWB–a blended wing body–to really bring something that's disruptive to the aviation world, the main goal is sustainability.”
Gasper also adds on about their current prototype:
“Our 4.5 meters wingspan demonstrator now flies very nicely and behaves like a glider, as we intended. It is fully radiocomm’d and serves two purposes: technical design and testing as well as marketing and communication. It has been flying since the end of 2023 and we are trying to implement a new function or sensor each time, step by step! In parallel, we have been working on the hydrofoils development demonstrator. It’s the same composite skins, therefore the same shape and air foils. It's not equipped with landing gears but with mounting brackets to accommodate our hydrofoil prototypes. This is going quite well!”
Gaspar shares an ambitious timeline: an intermediate scale demonstrator, around 8 meters wingspan (¼ scale), by 2026. The goal is to validate the excellent aero efficiency and scaled sub systems. It is also a means to identify obstacles in the production process, particularly on composite parts. Then a full-scale demonstrator by 2029, followed by regulatory certification and the first commercial flights around 2032. With battery energy density expected to double by then, payload and range will improve organically. By 2035, Eenuee aims to deliver 50–100 aircraft, all designed for simplicity—favoring mechanical controls over complex avionics to ensure maintainability and resilience in supply-chain disruptions.
Eenuee’s blended-wing, electric amphibious plane embodies EcoAero’s vision of sustainable flight: leveraging innovation to decarbonize aviation without waiting for incremental fuel swaps. As EcoAero continues to spotlight pioneering work in aerospace sustainability, we’ll be closely tracking Eenuee’s progress—and sharing each milestone in our ongoing quest to accelerate the future of clean flight.
