Programme Name

Clean Aviation Joint Undertaking (CAJU)

Programme Description

The Clean Aviation Joint Undertaking (CAJU) is a successful public-private partnership between the European Commission and the European aeronautics industry that is on the way to achieving its environmental performance targets.

The Clean Aviation JU will develop disruptive new aircraft technologies to support the European Green Deal, and climate neutrality by 2050. These technologies will deliver net greenhouse gas (GHG) reductions of no less than 30%, compared to 2020 state-of-the-art. The technological and industrial readiness will allow the deployment of new aircraft incorporating these technologies no later than 2035, enabling 75% of the world’s civil aviation fleet to be replaced by 2050. The aircraft developed will enable net CO2 reductions of up to 90% when combined with the effect of sustainable ‘drop-in’ fuels, or zero CO2 emissions in flight when using hydrogen as energy source.

Clean Aviation’s aeronautics-related research and innovation activities, focusing on breakthrough technology initiatives, will contribute to the global sustainable competitiveness of the European aviation industry. European aviation research and innovation capacity will be strengthened through the partnership, enabling new and ambitious global standards to be set.

Demonstration of an Optimized System Platform for Ultra-efficient SMR Aircraft

Summary

Development and demonstration of an optimized systems platform enabling the next-generation Ultra-Efficient SMR aircraft. The topic aims to integrate high-performance computing, electrical power and data architectures into a unified, certifiable platform, supporting advanced functions such as active control, hybridisation and predictive maintenance by means of a representative ground demonstration at TRL6 validating performance, safety and cybersecurity, with clear pathways to CRL4 and future maturation towards aircraft integration and EIS 2035.

Detailed Call Description

The Ultra-efficient Short and Medium Range (SMR) aircraft concept targeted in Clean Aviation are expected to integrate a set of disruptive technologies characterized by a fundamental change in the requirements for system platforms. Innovations such as active control of high aspect ratio (HAR) wings, hybridisation and predictive maintenance – create a level of complexity which conventional system architectures cannot sustain. Future SMR aircraft are expected to require higher than thirty times more computing power, five times more electrical power and two orders of magnitude higher data throughput as compared to the last generation of large passenger aircraft in service.
