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 Ultra-Efficient Rear Fuselage and Empennage and Its Integrated Industrial System enabling EIS2035 for the SMR Aircraft

Summary

Development and demonstration of an Ultra-Efficient Rear Fuselage and Empennage (RFE) and its integrated industrial system for the Ultra-Efficient SMR Aircraft. This topic targets the delivery of a RFE full component assembly alongside an Industrial system including advanced manufacturing and assembly processed supporting the high-rate production of such structural components at TRL6, with an aim to significantly reduce the weight at component level and increase competitiveness through co-development of product and production processes, ensuring a clear route towards certification, exploitation and industrialisation for EIS 2035.

Detailed Call Description

The configuration of the Ultra-efficient SMR aircraft concept proposed in Clean Aviation is expected to maintain a tube and wing design and target Entry into Service (EIS) by 2035. Such an aircraft concept should have a capacity of200-250 pax with a design range up to 3000NM, operated on a typical mission of 800NM at cruise speed Ma 0.78.

To meet the future demand and enable the EIS by 2035 of the Ultra-Efficient SMR aircraft, the production rate needs to increase significantly. However, the aircraft manufacturing ecosystem remains constrained by the effects of supply chain disruptions, labour shortages, and limited availability of critical component, leading to backlogs and delayed fleet renewal. These industrialization challenges need to be addressed now, to accelerate aircraft production rates and support the future modernization of the global fleet with the Ultra-Efficient SMR. This is also critical to strengthening of the European aviation competitiveness.

The project aims to validate a co-development approach towards design, manufacturing, assembly and quality control processes that are suitable for high-rate, sustainable aircraft production to TRL6 and a specific focus on industrial readiness and manufacturing. The project should demonstrate that the RFE is designed to meet a coherent set of requirements for the Clean Aviation Ultra-efficient SMR aircraft concept from the ACIandI (GA n. 101255025) project. The RFE will maximize the CO2 emissions reduction contribution at aircraft level by integrating technologies that focus on both weight and drag reduction matured and demonstrated at TRL6, coupled with advanced manufacturing techniques matured and demonstrated at TRL6.
