The EU project EXAELIA, coordinated by NLR, seeks to accelerate the reduction of aviation emissions and environmental impacts by evaluating novel flying test beds for future aircraft development. With the European aviation industry facing challenges due to its significant carbon footprint, initiatives like the Clean Aviation program and EXAELIA are vital. The EXAELIA project, officially launched in Amsterdam, aims to develop disruptive future aircraft concepts to achieve carbon neutrality in aviation by 2050. By focusing on radical changes in aircraft configurations and propulsion, EXAELIA targets a significant reduction in emissions. The project investigates blended wing body and hydrogen-powered tube-and-wing aircraft configurations through digital methods and flying test beds. Through a comprehensive partnership involving major European research centers, academia, and SMEs across 13 countries, EXAELIA aims to drive innovation in future aviation. The project's budget of 16.4 million Euros under the Horizon Europe Programme showcases the commitment to sustainable aviation. By preparing roadmaps and business plans, EXAELIA aims to ensure the successful development and entry-into-service of long-range aircraft before 2050, aligning with global net-zero targets.
