The EFACA project consists of 6 main objectives at 3 levels. Level 1 consists of three TRL3 demonstrations of technologies relevant to the greening of aviation: (WP1) bench testing of a gearbox combining input from gas turbine and electric motor for an hybrid turbo-electric propulsion system for a propeller-driven regional aircraft; (WP2) comparative testing of fuel cells with conventional liquid and novel phase cooling, to show the benefits up to 20% of the latter in higher net power, reduced heat losses, and smaller volume and weight also reengineering of fuel cell and structural components to increase power-to-weight ratio up to 80%; (WP3) static ground testing of a complete liquid hydrogen fuel system from cryogenic tank to vaporization and combustion in a wide range of operating regimes and simulation of application to the speed and altitude flight envelope of jet airliners. Level 2 consists of two preliminary designs: (WP7) an 80-seat 1000-km range regional propeller driven aircraft including design and integration of hybrid turbo-electric propulsion; (WP89) a 150-seat 2000-km range jet liner with liquid hydrogen fuel including design and integration of cryogenic tanks and fuel system. At level 3 a road map (WP10) for the achievement of the EU environmental targets for aviation synthetizing conclusions in four steps: (i) current status on (WP4) emissions and (WP5) noise versus future targets and gap to be covered; (ii) assessment of relevant technologies to cover the gaps, including (WP6) battery electric and (WP9) sustainable aviation fuels, besides hydrogen (WP7) fuel cells and (WP8) turbines; (iii) most suitable technology for each class of aircraft (light, small and medium regional, single and twin aisle jetliners), and maturation time of the technology; (iv) contribution of each aircraft class to CO2 and non- CO2 global and local emissions and noise, leading to (WP10) a comprehensive road map of actions for carbon-free or emissions-free flight.

TELEMETRY will provide trustworthy tools that enable the continuous assessment of heterogenous, interlinked components & systems that constitute IoT ecosystems (interconnected IoT devices with hardware, software, services and communications infrastructure). Addressing all aspects of their lifecycle, the TELEMETRY holistic methodology and toolkit incorporates: testing for component development, testing & monitoring for component integration into systems, testing & monitoring for operation of systems. TELEMETRY will deliver advances in cybersecurity testing and runtime monitoring through the use of novel machine learning models and algorithms for real-time anomaly detection; dynamic risk assessment to simulate likelihood and severity of threat consequences; reputation management and privacy-preserving data sharing across independent entities (e.g. supply chains), IoT device emulation and analysis environment and lightweight approaches for trusted updates; all of which that promotes a cycle of continuous improvement and assurance across design and runtime phases. TELEMETRY will leverage 3 exemplar use cases representing diverse, complex IoT ecosystems and IoT supply chains in aerospace, smart manufacturing and telecommunications domains to drive the design and validation of the proposed tools and methodologies. This will lead to significant improvements with respect to accuracy of threat and vulnerability detection, response time and cost of testing and verification of IoT ecosystems. TELEMETRY will promote open source and knowledge sharing through engagement with relevant communities throughout the project for consultation, dissemination and exploitation of its results.
