Europe and Canada bring their knowledge acquired in past programs on Electromagnetic (EM) coupling, antenna siting on aircraft, Cosmic Radiation (CR) effects and modelling methodology:
GENIAL – optimizinG Electrical Network In AirpLane composite structures (2012-2013)
EPICEA partner involved: IDS
GENIAL project aimed at developing a numerical methodology and a CAE (Computer Aided Engineering) tool suited to model the current return networks installed aboard aircrafts also having parts made in composite materials. The numerical model was validated with respect to measurements carried out on a very complex mock-up resembling almost all the situations can occur on a real aircraft.
ARROW – Aircraft lightning thtRreat Reduction thrOugh Wiring optimization (2013-2015)
EPICEA partners involved: IDS, ONERA
The ARROW project was focused on the development of a numerical methodology and a CAE tool to model user defined cable-harness configurations installed aboard an aircraft equipped with an ALmost Equipotential Electrical Network (ALEEN) and made of composite and conductive materials. The aim was to evaluate voltage and currents at equipment loads induced by a lightning strike on the aircraft, in order to allow the verification of their compatibility with the design and qualification values.
HIRF-SE – HIRF Synthetic Environment (2008-2013)
EPICEA partners involved: ONERA, AXESSIM, IDS
The HIRF SE research project had the goal of providing the aeronautics industry with a framework which can be used during the development phase to mitigate the EM aspects. In addition it aimed at providing a considerable reduction in the certification/qualification tests required on air vehicle for HORF environment. The HIRF SE main objectives can be summarized by the two followings items:
- Full validated and integrated solutions to model, to simulate numerically and to test air vehicles for EM aspects during design and certification;
- To build (from past and ongoing works) an integrated approach with an open and evolutionary architecture.
TAUPE – Transmissions in aircraft on unique path wires (2008-2012)
EPICEA partners involved: ARTTIC, ONERA
The technologies for power and data transmissions over unique path wires are strongly developed. The former OPERA project made feasible High Speed/High Voltage transmissions for Power Line Communication. The U-Broad project demonstrated that Fast Ethernet (100 Mb/s) can be provided over existing telephone network cabling. But, even if these technologies have been rapidly exploited in the automotive sector, they cannot be implemented ‘as- is’ in aircraft due to aeronautics-specific severe constraints (weight, space allocations and safety).
From POA results, the All Electric Aircraft is replacing conventional systems (hydraulic and pneumatic) with electric systems. But it is currently facing a drastic issue: the increase of the number of wires (each electric system needs power supply and communication networks) with an impact on weight and space allocation. To save weight and space, the solution is to use a unique path wires to transmit power and data. But even if the related technologies are now mature, each technology has its own dedicated wires architecture. The aeronautic sector now needs innovative solutions to merge the architectures in one full avionics-shared electrical and numerical network.
To enable the All Electric Aircraft, the TAUPE project defined a fully optimized avionic architecture for power and data transmission on unique path wires. From this optimized architecture, the related specifications was provided (harness wiring and network equipments) and requirements for systems qualification delivered.
The TAUPE results addressed the ACARE SRA and the Workprogramme (the Cost Efficient Air Transport) considering (on the A320) the TAUPE’s impact:
- weight reduction of 300 Kg approx (around 180 tonnes of fuel saved per day for the entire A320 fleet);
- easy and cost effective installation and retrofit with approximately 30% of installation and retrofit time saved;
- cost effective maintenance time saved with approximately 20% of maintenance time saved.
IPAS – Installed Performance of Antennas on AeroStructures (2003-2007)
The purpose of the programme was to improve computer-aided engineering design and evaluation capabilities (computational and measurement methods) for the installation of antennas on aircraft structures. This was achieved by bridging the frequency gap in computational electromagnetic tools using refined hybrid and multi-domain methods and the development of fast solver methods for solving full-wave integral equation methods in the frequency domain.
ANASTASIA – Airborne new and advanced satellite techniques amp technologies in a system integrated approach (2005-2009)
The project ‘Airborne new and advanced satellite techniques and technologies in a system integrated approach’ (ANASTASIA) was basically a technology oriented research program, which aimed at defining the new on board satellite-based navigation and communication systems.
To this aims, a review of the future needs of the various airspace users was first performed. Then, a detailed analysis of the satellite-based navigation and communication potentialities has been performed, and validated by mockup and flight trials. It allowed transformation of the initial ‘nice to have’ list of needs into ‘possible to achieve’ requirements.
The output of the project was the definition of possible architectures for the future avionics beyond 2010, the recommended techniques, technologies and proposed evolutions to international standards. An important strategic impact of the project was to help position European aviation industry in these competitive and strategic new domains.
EM-HAZ – Methods and technologies for aircraft safety and protection against electromagnetic hazards (2000-2003)
EPICEA partners involved: ONERA
The project developed efficient methods and technologies to handle electromagnetic effects, inclusive lightning strikes to aircraft. The developed methods and technologies focused on the emerging need from the European aircraft industries to use new composite materials; new structural concepts; new advanced avionics concepts, especially IMA and more electric aircraft. For all of these new technologies, each of them contributes to further increase in the technological and competitive advantage of the European aircraft community. Electromagnetic aspects and efficient protection and certification strategies have a major impact. EM-HAZ main outputs were a tool for lightning zoning, an in-flight design and development support, efficient protection strategies, compliance demonstration and maintenance routines.
FP4-FULMEN – Analysis of experimental data and models for upgraded lightning protection requirements (1996-1999)
EPICEA partners involved: ONERA
The main aim of the project was to provide the European aeronautical administration with new methods for defining the lightning threat for each new aircraft and provide a more realistic and quantitative evaluation of the threat level to be sustained by the structure or equipment. The sub-goals were:
- Establishing a critical analysis of present regulations.
- Providing a comprehensible collection of field lightning data.
- Elaboration of an analysis and physical study of lightning/aircraft interaction both for internal (equipment level) and external threats (airframe level).
- Global synthesis of findings including new definitions of the external threat, zoning and test waveforms, and corresponding upgraded regulation requirements.
- Setting up statistical evidence of correlation with observed measurements or incidents.
