Periodic Reporting for period 2 - GAM-2020-AIR (AIRFRAME ITD)

Reporting period: 2021-01-01 to 2021-12-31

Airframe ITD will support technology de-risking at a major system level, to be further integrated in the vehicle integrated demonstrators. The scope is to bring novel technologies up to TRL6 at airframe level to be integrated and tested at the global aircraft level.
Innovative Aircraft Architecture is investigating some radical transformations of the aircraft architecture and demonstrate the viability of some of the most promising advanced aircraft concepts. This will be done by identifying the key potential showstoppers and exploring relevant solutions.
Advanced laminarity is a key technological path to make further progress on drag reduction which will be applied to major drag contributors, especially the nacelles and wings.
High Speed Airframe is focused on step changes in fuselage and wing, enabling better aircraft performance and quality of delivered mobility services. The aim is to reduce fuel consumption without compromising the overall aircraft capabilities such as low speed and versatility.
Novel Control will introduce innovative control systems and strategies to make gains in overall aircraft efficiency.
Novel Travel Experience investigates new cabin concepts including layout and passenger-oriented equipment and systems as key enablers of product differentiation. These concepts have an immediate and direct physical impact on the traveler.
Next Generation Optimised Wing will lead to progress in aero-efficiency and in better, more durable, affordable and lighter-weight wing structures through the design, build and ground testing of innovative wing structures. .
Optimised High Lift Configurations will progress on the aerodynamic efficiency of wing, engine mounting and nacelle integration for aircraft that serve local and remote airports, thanks to excellent take-off and landing and field performance.
Advanced Integrated Structures will optimise the integration of systems in the airframe along with the validation of important structural advances, thereby boosting eco-production efficiency and manufacture of aircraft structures.
Advanced Fuselage addresses innovation in fuselage shapes and structures, including cockpit and cabins. New concepts for the fuselage that support more optimised aircraft and VTOL vehicles will be introduced. More radical aero structural optimisations and new schemes are required for further improvements in drag and weight reduction in the context of growing cost and environmental pressure, including the emergence of newcomers.
Eco-Design focuses around eco-design activities embedded in Airframe ITD. These are mainly concentrated around developing environmentally sound technologies, and on performing Life Cycle Assessment activities to quantify the benefit brought about by the newly developed technologies. The Eco-Design Thematic Areas target the environmental benefits addressing lower negative impacts during the production of aircraft parts, their maintenance phase, as well as the aircraft’s end of life phase.
Airframe ITD is addressing the full range of aircraft types and is structured around three major Activity lines split into technology Streams or Work Packages: High Performance & Energy Efficiency (HPE), High Versatility & Cost Efficiency (HVC), and Eco-Design (ECO).

High Performance & Energy Efficiency (HPE)

Under this activity line, innovative aircraft architectures are investigated which the aim to demonstrate the viability of some of the most promising advanced aircraft concepts by identifying the key potential showstoppers and exploring relevant solutions, elaborating candidate concepts and assessing their potential. Advanced laminarity technologies as those related to extented laminarity will also be developed as considered as a key technological path to make further progress on drag reduction, to be applied to major drag contributors, especially the nacelles and wings. High speed airframe activities will be focused on the fuselage and wing by enabling better aircraft performance and quality of the delivered mobility service, with reduced fuel consumption with no compromise on overall aircraft capabilities (such as low speed abilities and versatility). Novel controls will introduce innovative control systems and strategies to make gains in overall aircraft efficiency. It will contribute to sizing requirement alleviations thanks to smart control of the flight dynamics. Finally, novel travel experience will investigate new cabins including layout and passenger-oriented equipment and systems as a key enabler of product differentiation, having an immediate and direct physical impact on the traveller, and with potential in terms of weight saving and eco-compliance.

High Versatility & Cost Efficiency (HVC)

Under this activity line, next generation optimised wing box will lead to progress in the aero-efficiency and to better, more durable, affordable and lighter-weight wing structures through the design, build and ground testing of innovative wing structures. The challenge is to develop and demonstrate new wing concepts (including architecture) that will bring significant performance improvements (in drag and weight) while improving affordability and enforcing stringent environmental constraints. From another hand, optimized high lift configurations activities will progress the aero-efficiency of wing, engine mounting and nacelle integration for aircraft that serve local airports thanks to excellent field performance. Advanced Integrated Structures will optimize the integration of systems in the airframe along with the validation of important structural advances, and to make progress on the production efficiency and manufacturing of structures. Finally, advance fuselage activities, that include also cockpit and cabins, will introduce new concepts of fuselage to support future aircraft and rotorcraft. More radical aero structural optimizations can lead to further improvements in drag and weight in the context of growing cost and environmental pressure, including the emergence of new competitors.

Eco-Design (ECO)

Eco-Design related activities, embedded in Airframe ITD, are mainly focused on developing environmentally sound technologies, and on LCI Data development to perform Life Cycle Assessment via ECO TA collaboration.
The Eco-Design Thematic Areas target the two following environmental benefits: lower impacts during the production of aircraft parts, the maintenance phase and end-of-life of the aircraft. In 2020 the Eco-Design activities were clustered to Flagship Demonstrators.
The Airframe ITD targets significant gains in the following areas:
• Introducing innovative/disruptive configurations enabling a step-change in terms of efficiency;
• Developing more efficient wings;
• Developing fuselages with optimized usage of volume and minimized weight, cost and environmental impact;
• Developing an enhanced technology base in a transverse approach towards airframe efficiency to feed the demonstrators on synergetic domains such as:
- Efficient wing technologies,
- Natural Laminar Flow and Hybrid Laminar Flow technologies,
- New production and recycling techniques,
- Progress on certification processes and associated modelling capacities which will be key to facilitate the market access of future step changes.

All those streams have shown feasibility to be developed into a more complex and demanded structural components to be used into Clean Sky 2 platforms.
