Adopting a new breed of aircraft is essential for reaching climate neutrality by 2050.

Decisive improvements in aircraft performance are going to be vital if we are to safely and viably reduce emissions in the future. According to the aeronautics community, virtual prototyping has the biggest potential to be the key enabling technology in achieving these objectives and making zero carbon aviation a reality.

CAELESTIS will develop a new interlinked system able to execute massive calculations and predictions across the aviation value chain. Digital twins will then be developed with unprecedented levels of detail covering manufacturing effects and deviations.

Accelerating the reduction of all aviation impacts and emissions is going to require speeding up the development of aircraft technologies, making disruptive efficiency gains by 2035. 

The research to be undertaken throughout the life cycle of CAELESTIS brings together a multitude of disciplines and areas of research. Our chief aim is to develop a robust and secure digital ecosystem, utilizing simulation-driven design to innovate a new manufacturing methodology able to transform the European aircraft industry – and reduce emissions along the way.

The technical outcomes of CAELESTIS could have huge potential impacts for the EU’s aviation industry, environment, and European society in general.

Disruptive efficiency gains could reduce fuel burn in the long run by up to 30%, while the innovation enabled by CAELESTIS could help SMEs and startups to better operate within a streamlined, market-oriented environment.

Additionally, the impact of CAELESTIS could create more and better jobs, accelerate digitalisation and generate inclusive growth contributing to the European Green Deal and a Europe fit for the digital age, with a renewed economy that works for the people.
