AKKA unveils Green & Fly, its 100% electric hydrogen concept aircraft

BRUSSELS, October 13, 2021– (BUSINESS WIRE) – Regulatory news:

Today, AKKA (Paris: AKA) (BSE: AKA) (ISIN: FR0004180537) unveils Green & Fly, its fully electric hydrogen concept aircraft, with a disruptive design based on a rhombohedral wing shape. Designed to carry up to 30 passengers over a range of 500 km, it is a zero-emission concept for regional flights.

Green & Fly is a regional transport alternative, which aims to improve mobility in medium-sized cities where there are no large hubs. Capable of dealing with runways of any length (Short Take Off Landing – STOL), it can operate on existing aerodrome networks, thus relying on underused infrastructure.

This concept combines the latest technologies and explores different configurations to optimize the aerodynamic performance and energy consumption of the aircraft, thus optimizing its electrification potential. Green & Fly is a light and small aircraft (CS25 classification) with a futuristic design and a sophisticated mechanism powered by hydrogen fuel cells and supercapacitors.

The rhombohedral shape of the wing, compared to a conventional wing shape, generates less turbulence at the wing tip allowing a significant reduction in drag, opening up new possibilities for a highly efficient propulsion system. The stiffening of its structures is inspired by biomimicry based on the process of growth of the veins of a leaf to improve the efficiency of the stiffening, thus reducing the mass of the aircraft. To maximize the utilization rate, the cabin design is flexible, which allows the aircraft to be easily converted from passenger to cargo. The cockpit integrates digital and AI applications to facilitate single-pilot operations. The aircraft design also incorporates an energy recovery landing gear, with electric extension / retraction, with the aim of gradually replacing all hydraulic components with electrical components to reduce emissions.

This project mobilized the most experienced aeronautical engineers from AKKA in France, Germany and Romania and illustrates the Group’s commitment to develop renewable energies and to contribute to the decarbonisation of the aeronautical industry, through technology and technology. ‘innovation.

Mauro Ricci, Chairman of the Board of Directors and CEO of the group from AKKA Technologies states: “I am extremely proud of our engineers who imagined this aircraft concept that we are unveiling today. Green & Fly showcases AKKA’s significant expertise in emerging and clean technologies, strengthening our position as a partner of choice for our customers in their transition to more sustainable products and solutions.
