The increasing demand for clean aviation is pushing the industry towards the all electrical aircraft, with cero emissions. The green deal of the European Commission is a clear high-level example of the commitment that all the countries all over the world should have. Recent advances in the last few decades in power semiconductors is moving the industry to the electrical propulsion, where the generation and electrical consumers are connected together in a small weak electrical grid. The amount of power to be managed by the electrical system is expected to be increasing in the following decade from a few Megawatts to power small aircraft to several tens of MWs to power long haul aircrafts. Although the technology to manage this amount of power is well known for typical ground distribution power grids, the concepts and components cannot be directly applied to aircraft application due to the size/weight required for an aircraft application and the fact of high altitude flying which means a lower pressure and air density. The evolution of aircraft electrical power management system to higher power is critical in the next few years to reach the objective of a future clean sky program. In this context, the overall objective of DCADE is the evaluation of potential technologies that will allow higher voltage converters while maintaining the power density and arc detection techniques that will increase the safety of high altitude, high power A/C distribution systems. Due to the nature of this CfP, DCADE proposal will focus on 2 of the 3 technologies described in the call text, these technologies are power electronics and electric power distribution. DCADE project will implement two demonstrators, one related to each topic. The first demonstrator will be at the facilities of Skylife in Seville (Spain) and the second will be in the facilities of IRTSE in Toulouse (France).

The SMR Aircraft Architecture and Technology Project (SMR ACAP) shall be the central place to assess and integrate all technologies at aircraft level, from across the projects in the SMR pillar. Establishing the link to projects with relevant technologies in the other Clean Aviation "Pillars" and transverse projects associated with novel certification methods is part of the work plan of the project. The setup of the ACAP project is tailored to steer and manage the definition of the targeted SMR aircraft configurations with all key performance features required for the SMR architecture. In order to accelerate the maturation of the SMR aircraft technologies, ACAP will provide a digital collaborative framework with tools, means and skills enabling to continuously link all R&T activities within the SMR pillar (strongly linked to other Clean Aviation pillars) to deliver solutions meeting the Clean Aviation high level goals: reduce the greenhouse gases by -30% compared to a 2020 state of the art technology; support the launch of new product by 2035, to replace 75% of the fleet by 2050, and exploit the synergies with other national and European related programmes. Coordinated by Airbus, the project consortium is composed of a well balanced mix of innovative actors from the aeronautical industry covering almost all technical disciplines of aircraft R&T complemented by a strong foundation of Academia and Research and Technology Organisations, which will be further widened with the planned linking to other CA projects. The ACAP project is aiming to identify "best athlete" SMR aircraft concepts before the end of CA phase 1 and, based on sound analysis of the expected impact with respect to the CA objectives, to propose which technologies shall be further developed and demonstrated in a Clean Aviation phase 2.

The IMPERIAL consortium will bring together their world leading expertise in the design and manufacturing of integrated Power Electronics (PE), advanced digital control systems, thermal management and scalable structure to develop an innovative advanced Direct Current High voltage (HVDC) to DC and AC converter for decentralized electrical power distribution network. The IMPERIAL consortium will combine their expertise in the technical areas of Power Electronics and digital control platform, as well as in modellisation and simulation for aerospace applications. The concept of IMPERIAL is essentially made of a rackable system called Secondary Electrical Power Distribution Centre (SEPDC) and two rackable power modules converting the distributed bus voltage HVDC +-270Vdc to 28Vdc for the first module and HVDC to 115Vac for the second one. The aim of IMPERIAL is to develop an innovative power converter that is able to perform power transmission, monitoring, diagnosis and communications. The system will be highly efficient, reliable, compact, and light, hence contributing towards higher performances, more efficient and greener future large passenger aircraft. By considering innovative solutions and components technologies for achieving high efficiency, low weight and size, high power density as main targets to fit in high temperature environment, the IMPERIAL project contributes into WP6.4 – Integrated demonstration and validation to the Systems ITD objectives

The main objective of HYPNOTIC project is the development of a set of bidirectional converters (at least 5), acting together as only one equipment. Specifically the equipment, composed by several DC/DC bidirectional converters (i.e., the “modules”) plus a supervisor, must be able to reconfigure itself as a consequence of load/source variations, referring to their characteristics and priority, and as a reaction to a fault or to other undesirable events, hence contributing to the maturity of any HVDC distribution Network. This modular architecture will support the design of a scalable converter (30 to 60KW) which could be used to support the integration of new HVDC sources. The HYPNOTIC converter will be connected to HVDC network of the aircraft on one side and to a HVDC battery on the other side which will provide an energy storage source. The converter will implement relevant control techniques to ensure the stability of the network and the battery, and to allow a smooth energy transfer in both directions. Hence, the scope of the project can be summarized as the design and development of a modular bi-directional converter, composed by hardware and software acting together in order to solve the Power Transfer problem of additional DC sources in any HVDC network. Objectives of HYPNOTIC project include: - Development of DC/DC converter cells with enhanced performances, including power density and reconfiguration capabilities. - Development of accurate simulation models, at both “behavioural” and “functional” levels, potentially also integrated with external environments for the aims of the energy management functionalities verification. - Implementation of reliable control laws to allow the parallelization of several HVDC sources - Demonstration of the operation of such converter inside any HVDC network

Rail is a fundamental service for modern societies and the backbone of a sustainable transport system. To meet the numerous challenges ahead, the global rail sector must increasingly rely on the emerging disruptive technologies such as advanced robotics, 3-D printing, high computing power and connectivity, etc. which are integrated with analytical and cognitive technologies that enable machine-to-machine and machine-to-human communication.On top comes the pressure to reduce energy consumption, pollution and the consumption of other resources. Mastering the breakthrough developments of new technologies is of capital importance for the railway industry to deliver smart and efficient solutions.Indeed, essential to the growth of the rail industry is the reduction of the overall life cycle exploitation costs of all rail sub-systems. The Traction Drive sub-system is one of the main sub-systems of a train as it moves the train converting energy from an electrical source (directly or via a chemical source) into a mechanical one. RECET4Rail will focus on the following new technologies for the Traction Drive sub-system: development of design approaches, end-to-end conception time evaluation and feasibility/performance study of 3D printing technologies for new traction’s components use cases; Dynamic Wireless Power Transfer system sizing for actual city profiles focused on opportunistic charging; improving the understanding of the robustness and reliability of high voltage SiC modules; and development of smart maintenance approaches enabled by predictive analytics, trained on big data. RECET4Rail will provide essential knowledge that will lead to future improvement of the high TRL level S2R traction demonstrations on trains done by the S2R Members, preparing also future S2R key work on domains like digitalisation applied to Traction, environmental sustainability (especially devising carbon free traction systems) or reinforcement of standardisation to lower complexity and costs
