Clean Aviation
Joint Undertaking

In force from 2021 under the patronage of Horizon Europe, it is the new public-private partnership of the European Commission for climate-neutral aviation. It represents the evolution of the Clean Sky (2007-2017) and Clean Sky 2 (2014-2024) programs in which the European Union has made available funding exceeding 5 billion euros in the field of research and innovation in the aeronautical sector.

Clean Aviation has the ambitious goal of helping the aviation sector to meet the objectives of the EU Green Deal (signed in 2020) and achieve climate neutrality by 2050. It builds on the extensive experience gained with previous programmes by building synergies and collaboration between Partnerships focused on breakthrough technological initiatives that help reduce noise pollution and CO2 and NOx emissions.

Three main thrusts provide the pillars of the new European partnership:

Hybrid electric and fully electric powertrains

Ultra-efficient aeronautical architectures

2
Disruptive technologies to enable hydrogen-powered aircraft

In Italy, the Clean Sky program has involved over 80 partners. In the Clean Sky 2 program that will end in 2024, it will provide more than 34 leading demonstrators and more than 1000 technologies with the participation of 63 partners.

In this great revolution now underway, not only will mechanical components undergo a transformation and leap forward, but we will also witness a true innovation in thinking. It is a scenario where everyone benefits: better for the environment, better for the public, better for the aviation sector, and better for the European economy.

Milestone

01
Kick off
Initial project setup phase. In this phase, the consortium shares objectives, timelines and intermediate milestones with the Topic Manager.
02
System Requirements Review
Following initial research useful for framing the objectives to be achieved with the technological context, the requirements and technical specifications of the demonstrator or prototypes to be built are shared with the Topic Manager. It is also known as SRR.
03
Preliminary
Design Review
It closes the preliminary design phase of the project. Its purpose is to review the conceptual approach to ensure that the planned technical activity meets the requirements. A PDR should present the basic system in terms of software, mechanics, power distribution, thermal management, and electronic design. Finally, the PDR should present preliminary estimates of weight, energy consumption and volume.
04
Critical
Design Review
The purpose of the Critical Design Review (CDR) is to review the design in detail to ensure that the design implementation meets requirements. The CDR closes the critical design phase of the project and presents the final designs through analysis, simulations, schematics, software code and completed test results. A CDR must be kept and signed before the project design is frozen and before any significant production begins. In fact, with the completion of the CDR, the production phase can start.
05
Test Readiness
Review
The Test Readiness Review (TRR) is conducted to determine if the system under consideration is ready to proceed to formal testing, deciding whether the testing procedures are complete and verifying their compliance with test plans and descriptions. A TRR is normally conducted prior to any type of major test setup, including hardware and software, and provides to the management the confidence that a system has undergone a thorough testing process and is ready for the next test phase.
06
Project Closure
In the case of a research project with a medium-high TRL, from TRL4 (Technological Development) to TRL 6 (realization of a Technological Demonstrator), the project ends with the completion of the test phases, the validation of the results and the drafting of summary and specification documents of the system examined and implemented.
