Scope

The project's objective is to address the environmental challenges associated with the production and full lifecycle of aircraft, from manufacturing to maintenance and the eventual disposal of their components. Aviation impacts the environment not only through the operation of transporting people and goods but also throughout the entire lifecycle of aircraft.

The project focuses on developing advanced materials and innovative technologies to reduce the environmental footprint of aircraft production. This includes creating new materials, processes, and recycling methods that lead to greener manufacturing, maintenance, and end-of-life benefits. The use of lightweight and high-strength materials such as Ti-6Al-4V alloys and 2XXX and Al-Li series aluminum is crucial for reducing CO2 and NOx emissions and minimizing waste.

Additionally, there is an emphasis on employing advanced technologies, such as laser welding and seam tracking and penetration sensors, to enhance the efficiency and quality of welded joints in large aeronautical structures.

Collaboration with major companies in the aeronautical sector and the integration of these technological innovations are essential to achieving these objectives.

Solution

The proposed solution of the project involves the application of advanced laser technologies to improve the efficiency and quality of welding large aeronautical structures. Laser welding with and without filler material is considered, applied to Ti-6Al-4V alloys and high-strength aluminum (2XXX series and Al-Li), with the ultimate goal of ensuring a high production speed (4 m/min) in structures that present additional challenges due to their length and curvature.

To ensure the quality of welded joints, seam tracking and penetration sensors will be used, allowing precise and real-time control of the welding process. This innovative solution is developed within the framework of the DELASTI, LIGHTWELD, and ECOTECH projects, and in close collaboration with companies in the aeronautical sector, thereby promoting technology transfer and strengthening industrial competitiveness.
