The challenge for Clean Sky 2's Large Passenger Aircraft Programme is to further mature and validate key technologies such as advanced wings and empennages design, making use of hybrid laminar airflow wing developments, as well as an all-new next generation fuselage cabin and cockpit-navigation.

NADiA project will research, develop, design, manufacture and test technologies and solutions aiming at significant improvements of the air distribution system (ADS), using the example of a 90 passenger advanced turboprop aircraft. The integrated improved cabin ADS is one of the key contributors to the environmental challenge of the ITD Airframe activities in reducing the structural weight by 4% to 6%, the CO2 and NOx, footprint by 3% to 5%, while enhancing passenger comfort by reducing noise and vibration. NADiA will significantly improve the ADS by 15% in weight, 3dB in acoustic and 20% in cost. Development, manufacturing costs and assembly times will be reduced, and production rates will be increased. To achieve the overall goals, ‘beyond state of the art’ technologies will be developed and verified in dedicated tests up to TRL6. The key end goal of NADiA will be to fully integrate and test the novel ADS in the cabin demonstrator located at Fraunhofer IBP in Holzkirchen (Topic Manager), as well as to provide support for the Environmental Control System (ECS) testing performed by Fraunhofer IBP. NADiA consortium applies advanced design principles, innovative system architectures, advanced materials and processes to generate high potential air distribution solutions for next generation turboprop aircraft. NADiA participants have a longstanding experience in ADS and ECS products. Diehl Aviation Laupheim integrates ADS for all Airbus aircraft programs, including the mixer for the A350. The delivered systems are developed and simulated using CAD and CFD software solutions. Diehl Aviation Gilching developed and manufactures vans and air cooling devices for several Airbus programs. NADiA total grant request to CS2JU is 1 299 271.25€ for the whole consortium and will be conducted within 36 months. Diehl Aviation Laupheim will complete the CS2 funding by bringing additional internal funding of 200 000€ to deepen the innovation work on materials and technologies.

Green hydrogen as a fuel offers the possibility to significantly reduce or even eliminate all of aircraft’s greenhouse gas emissions. When liquid hydrogen (LH2) is used in fuel cells (FC) for power generation, this results in no CO2, no SOx and no NOx emissions. The best way to achieve this solution is to develop a hydrogen propulsive FC system as an integral part of a new LH2 aircraft concept. This means moving away from the current “plug and play” (separate motor development and aircraft architecture) philosophy towards a disruptive integrated way of development, which requires a co-creation approach of the propulsion system and the aircraft. FAME follows this approach by collaborative research and development between on one hand partners involved in development of the needed systems of the fuel cell and on the other hand Airbus as and aircraft designer, manfacturer und integrator. Thereby it is ensured that on all levels from material over component and sub-system up to propulsion system on aircraft level an optimization is realized. The focus of FAME is on developing a complete compact high-efficiency full electric propulsion system based on LH2 as energy source for short to medium range (SMR) aircraft. FAME will develop all the subsystems which are needed and integrate these in a MW FC Propulsion System ground demonstrator with the vision to scale it up to aircraft level (sufficient for SMR aircraft). FAME shows the feasibility of a multi-MW FC Propulsion system for hydrogen-powered SMR aircraft. The system will provide the basis for Clean Aviation in phase 2 to undergo a system flight test.

Main objective for the Clean Sky 2 Large Passenger Aircraft Programme (LPA) is to further mature and validate key technologies such as advanced wings and empennages design, making use of hybrid laminar airflow wing developments, the integration of most advanced engines into the large passenger aicraft aircraft design as well as an all-new next generation fuselage cabin and cockpit-navigation. Dedicated demonstrators are dealing with Research on best opportunities to combine radical propulsion concepts, and the opportunities to use scalled flight testing for the maturation and validation of these concepts via scaled flight testing. Components of Hybrid electric propulsion concepts are developed and tested in a major ground based test rig. The LPA program is also contributing with a major workpackage to the E-Fan X program. The R&T activities in the LPA program is split in 21 so-called demonstrators. In the project period 2020 and 2021 a substantial number of hardware items ground and flight test items will b
