This report presents the conceptual design of the EverWing, an ultra-low-impact, 150-passenger commercial aircraft of which all parts, except the powertrain, can be remanufactured or recycled into comparable parts for a similar aircraft for entry into service in 2050.
A blended wing body configuration was chosen for its improved aerodynamic and volumetric efficiency with respect to other configurations. As a result of subsystem analyses, the aircraft features a 35.5-meter wingspan, cruise speed of Mach 0.80 at an altitude of 12.2 km, and a lift-to-drag ratio of 18.2 during cruise. Furthermore, EverWing is propelled through four ducted fans powered by liquid-hydrogen fuel cells and electric motors.
To ensure recyclability, the structure utilises CFR-PEEK and Al-Li alloys, enabling disassembly at end-of-life. Life-cycle assessment shows the end-of-life recovery avoids 394 tons of CO2-equivalent emissions and that EverWing offers a 87% reduction with respect to the A320neo throughout its whole lifetime, plus a 100% reduction in CO2 and NOx during operations. The design achieves a direct operating cost of 0.030 EUR per seat-kilometer and a 40.3% return on investment at an expected market price of 105 million EUR.
