The More Electrical Aircraft Domain addresses the challenges of technological breakthroughs with the aim of cutting CO2 emissions in half by 2050 based on the ambitious goals set by IATA. Its expertise in electrical engineering means that the domain lies at the crossroads of every air transport, automobile and rail industry.
The technologies are grouped together in 3 competence centers:
The Domain helps to develop solutions that help replace hydraulic and pneumatic energy with electric energy, leading to global energy optimization on aircraft. It also participates to the electrification of propulsion requiring voltages of up to 3,000 volts on small carriers and hybrid solutions on large transporters. Thanks to their flexibility, the architecture can be redesigned with overall optimization of the aircraft and propulsion system.
The Domain delivers tools (demonstrators, tests, databases, models, optimization algorithms, guides, methodologies, recommendations for standards, etc.) to increase the power density of all the components in the electromechanical conversion chain and to reach overall optimization (loss reduction, 3D integration, interaction analysis and cooling). It uses new large-gap components, which are emerging in power electronics, and helps to build new technological bricks to boost the overall performance of converters, various components and electric motors. It also takes into account the aggravating factors of physical phenomena due to altitude, such as electric arcs and the partial discharges responsible for component failures, premature ageing and damage to electrical insulation systems.
