The EPICEA project intends to release, validate and verify a computer environment (i.e. the EPICEA platform) compiling a complete understanding of Electromagnetic (EM) issues on Composite Electric Aircraft (CEA). This includes EM coupling on interconnects and Cosmic Radiations (CR) on electrical systems together with new concepts of antennas designed to maintain performance in composite environment without modifying aircraft aerodynamics.
The EPICEA platform will support a decision making process for selection of the best strategy for the integration of electrical systems. Starting at Technology Readiness Level 3 (TRL3), the consortium will demonstrate a TRL4 at the end of the project.
Research and technical activity in EPICEA is organized in 5 technical Work Packages (WP1 to WP5) framed by a WP for the dissemination and the exploitation (WP6) and a WP for the management of the project and the coordination of the Research, Innovation and Action (RIA).
WP1 Technology Maturity Assessment
WP1 will give the whole set of specifications for High-Intensity Radiated Fields (HIRF) Lightning and Electrostatic Discharge (ESD) environments, as well as for the CEA environment, the requirements in terms of modeling and in terms of validation to be performed in WP5. Requirements on simulation and computer tools and methodologies to be further developed in WP2, WP3 and WP4 as well as the EPICEA computer platform requirements will be defined in WP1. WP1 will also define the demonstrations to be made in WP5 and make the weight assessments on WP5’s extra configurations of the reference system. Finally, WP1 will define the roadmap towards aircraft applications at higher TRLs. WP1 will thereby support all the technology maturity assessment activity and the TRL4 review.
WP2 EM coupling on Interconnecting Systems (IS) in CEA
WP2 will develop numerical models and implement, on the basis of the requirements of WP1, modelling tools and scenarios to be integrated in the EPICEA platform in order to be able to evaluate EM coupling onto IS in the CEA, induced by EM environments such as lightning and HIRF at low and high frequencies.

WP3 Antennas on CEA materials
WP3 will work on models of advanced materials and analyze future concepts of antennas onto the CEA, as conformal antennas or multi-function antennas. WP3 will also develop a numerical methodology through the EPICEA platform that will be specifically improved taking into account the installation constraints related to the CEA in order to evaluate antenna performances and compliance towards WP1 requirements (including conventional EM).

WP4 Cosmic radiation effects on CEA electrical systems
WP4 will characterize CR environment into the CEA and evaluate their effects onto embedded electrical functions for CEA’s high-altitude and new- flight route environments. WP4 will also develop a strategy based on experimental data and modelling, implemented in the EPICEA platform in order to predict CR effects at component and system level.

WP5 EPICEA’s methodology validation and demonstration
WP5 is dedicated to the experimentation phase defined in WP1. The preparation of the EPICEA mock-up including the reference EPICEA system will be made in WP5. Validation will consist in comparing modelling results to measurement results in order to validate the EPICEA modelling methodology developed in WP2 and WP3 for conventional EM and WP4 for CR. Additional extra configurations of the reference system installed in the mock-up will be also modelled in order to evaluate other architectures in terms of EM performance to EM and will provide the results for weight assessment in WP5.
WP6 Dissemination and Exploitation
WP6 will guarantee and promote EPICEA’s exploitation plan and deploy the resources for the dissemination of all the knowledge gained in the project. The two dissemination events, the workshop in Canada (Month 24) and the final public workshop in Europe hosted by ONERA (Month 36) will be the key events of this dissemination activity.
WP7 Project Management and Coordination of the RIA
WP7 will concern the management of all the financial and administrative aspects of the project. The coordination with the funding agencies and the consortium will be made both at the European side and at the Canadian side.
The EPICEA project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 689007.
