The Hybrid Electric Regional Wing Integration Novel Green Technologies¹ (HERWINGT) project is one of the game-changers to drive the transformation toward the decarbonization of aviation systems. It aims to design a novel wing, ideal for the future Hybrid-Electric Aircraft of the Regional Segment, and to develop architectures, structures, and technologies allowing higher integration of electric systems. Through these disruptive solutions, it will be pursued a 50% fuel burn reduction, at the aircraft (A/C) level compared to a 2020 State-Of-Art (SoA) A/C, in three different ways:

• Pioneering wing configurations and improved aerodynamic leading to drag reduction and enabling a fuel burn reduction of 15% at the wing component level, compared to a 2020 SoA wing.

• Wing structures, more integrated systems, and new material technologies resulted in a weight reduction of 20% at the component level, compared to a 2020 SoA wing.

• The development of technologies enabling the wing for a hybrid-electrical use case (H_²/Batteries + fuel systems using Sustainable Aviation Fuels (SAF)) 

HERWINGT also commits to delivering: 

• Digital twins and a life cycle assessment of the components, subsystems, and full wing system compatible with the reference aircraft digital framework and requirements 

• Α roadmap toward the wing full-scale demonstration at A/C level with a first flight and proposes a qualification and certification plan linked to the proposed activities and suitable for Hybrid-Electric Regional Aircraft. 

The final product of the project will be available for Entry Into Service (EIS) in 2035 for Regional Aircraft.

¹ Novel Green Technologies considered in HERWINGT takes into consideration new materials, structural concepts, integrated systems and drag reduction technologies in order to have 50% fuel burn reduction at the A/C level but also to reduce industrial wastes associated to manufacturing of such A/C
