    The aircraft industry has long been concerned with the increase of drag impacting directly the fuel consumption of airplanes. Different researches have shown that the insect sticking causes a surface roughness disrupting the laminar flow. Several methods have been used to solve the problem and the most important parameter playing a role in the reduction of insect adhesion on aircraft wings is the surface energy. Indeed, during the last 60 years different modifications of the wing leading edges such as elastic surfaces, soluble films or fluid covers have been proposed. The use of coatings to mitigate the insect contamination shows great potential but critical issues still remain due to lack of durability. The objectives of CHOPIN are the development of highly durable hydrophobic coatings which can be applied to micro-perforated surfaces typically used for drag reduction and the validation of the technology and the coating process proposed by using tests clearly assessing the mitigation of insect contamination under realistic conditions. Different technologies are considered in the project which presently allows to obtain hydrophobic surfaces : wet-chemistry deposition and dry technologies (plasma and spray). To meet the application requirement these coatings will be optimized. Furthermore, the application process needs to preserve the holes and keep the efficiency of the HLFC leading edges. The efficiency of the proposed technologies will be compared to the commercial products and the coatings will be characterized by lab and simulated tests. Indeed, firstly, a classification considering the adherence to the substrates, the hardness, the flexibility, UV resistance, rain and sand erosion resistance and the resistance to aircrafts liquids will be done. The insect contamination and cleaning behaviour of the best coatings will be then demonstrated both, during simulated environment and during representative environment. Test under real condition will be done using drones which will allow a statistical evaluation of the insect impact and contamination behaviour of typical A/C leading edges under realistic A/C environment during take-off, landing and flight.

    In the space industry, a growing demand is to make structures lighter, while optimizing the mass/stiffness/strength ratio.. To do so, the sandwich architecture appears to be the most efficient design. The main objective of Sandwich Material and Structure (SMS) project is then to develop an ultra-stable and low weight structure, based on such architecture. This optimized structure will combine innovative solutions such as cyanate-ester / pitch fiber Carbon Fiber Reinforced Polymer (CFRP) raw material, cyanate-ester / pitch fiber CFRP honeycomb and advanced joining solutions. To validate the performance of such assembly, SMS will work on a sandwich mirror structure use case.. The development of a groundbreaking joining solution, based on organic, inorganic or hybrid chemistry, will ensure optimal structural cohesion. The implementation of Zerodur® skins to create the mirror will allow to measure optical performances and to characterize the stability of the structure. SMS work plan includes the identification of requirements at system and building blocks level, the development of European sourced cyanate-ester CFRP and CFRP honeycomb, the tuning of an efficient joining method and a Breadboard prototyping and tests. SMS project will ensure the compatibility of its developments with the European legislation and regulation, as well as foresee their up-scaling at industrial level and their dissemination towards research groups and SMEs. All the achievements will focus on developing a range of new space products from non-space low TRL technologies. At project end, SMS will achieve a Technological Readiness Level (TRL) 4-5, with the identification of the way forward to qualify and industrialize very large scale structures. SMS will be supported by a well-balanced and transdisciplinary consortium, with previous common experience in carrying out successful material and processes development projects.

    The aircraft industry is facing issues with the increase of drag directly impacting the fuel consumption of the fleet. Achieving natural laminar flow requires high surface quality. Tiny air flow disturbances at the surface can indeed cause an early transition from laminar to turbulent flow. The accumulation of insect debris on the leading edge of laminar wings has been recognized as one of the most significant operational concerns associated with laminar flow. The main objective of STELLAR is to develop efficient and durable anticontamination coating and cleaning solutions designed following a deep understanding of the insect residues properties. Hence, STELLAR project seeks to gain insight on the understanding of the biochemical transformation of hemolymph during flight phases and the consequent physico-chemical modification and interaction with the aircraft surface. In order to meet these goals, the project consortium gathers cutting edge multidisciplinary knowledge and the needed facilities to provide a deep understanding of the insect contamination issues. STELLAR approach has the potential to significantly enhance the current understanding of the key issues and highlight which surface characteristics have the greatest influence on insect residue adhesion. From this approach, new coating and cleaning solutions will be developed. The knowledge acquired and the coating and cleaning solutions developed will be evaluated through large scale tests: 1) wind tunnel tests will allow the simulation of the extreme conditions occuring during flights and 2) real aircraft tests, including short flight tests (on test aircraft) and long flight tests (on commercial aircraft), operating at higher altitudes will allow a full validation of the new solutions developed by the STELLAR project.

    Perovskite photovoltaics have seen rapid advances in the last decade with the promise of higher efficiency, reduced embedded energy and CO2 emissions, low-temperature production for versatile applications such as flexible photovoltaics and all at potentially much lower cost than current Si technology. However, poor stability and short lifetime in the field is holding back wide deployment of perovskite photovoltaics. The current best performing materials also contain lead (Pb) which is toxic and damaging to health and the environment. To address these limitations, SUNREY will tackle the root causes of these limiting factors through a suite of innovations covering all aspects of the device design and manufacture including improvements to the stability/performance ratio of the perovskite materials themselves, development of new charge transport and electrode materials and low-cost deposition methods that can be configured to different perovskite absorbers, development of improved stability Pb-free materials, development of a range of measures for barriers and encapsulation from layers to module and process optimisation. These technology developments will be underpinned by new approaches to degradation mechanism analysis and the incorporation of modelling to combine barrier properties data with device performance models and test data. The design process will be driven by lifecycle, circularity and sustainability analyses. Developments will be validated to TRL5 through testing by an accredited laboratory under both realistic laboratory conditions and outdoors. SUNREY targets a breakthrough combination of high efficiency (25% Pb-based, 15% Pb-free) with long lifetime (25 years), reduced emissions and cost of manufacturing compared to Si. This will open up a wide range of new opportunities for the consortium companies including utility-scale panels, IoT and MicroPower, Independent Power Sources, Building Applied Utility Power (BAPV) Building-Integrated Photovoltaics.
