The objective of this work package is to set the boundaries in which the research in this proposal will be performed.
Therefore, output of this work package
will be used in all consecutive work packages. The boundaries will be based on the main areas of the research:
- Overall system design and architectural structure.
- The electromagnetic environment, which is subdivided into the power system and equipment, and the compatibility
of the used equipment.
- The thermal household design parameters.
-Specification for system integration, which allows for a trade-off optimization strategy w.r.t. EMC/Thermal/Hardware/
The objectives of this work package is to develop accurate and validated models and tools to evaluate new EMC concepts related to Power electronics and EWIS in hybrid/electric propulsion.
Both power electronics and EWIS face new challenges when introducing hybrid or full electric propulsion in modern
aircraft. In work packages 4 and 5 new concepts that are compatible with such new challenges are defined, down selected
and evaluated. In support of this process, new models and tools will be developed, and existing tools will be updated, to
be applicable to the new systems and signals corresponding with electric propulsion. Models and tools will be validated
by measurements, for which the EMC facilities at NLR will be used.
This work package will use the scope for the power electronic system obtained in WP1. The tools and models that are
developed in this work package will at its turn be used in designs and evaluations of new concepts in work packages 4
and 5.Finally, there is also a strong link with WP6, where integration of several concepts with the EVE electric platform
takes place. Based on experiences and measurements here, some feedback in the sense of verification and tuning of
models created in this work package will take place.
Hybrid electric propulsion dramatically increases the electrical power in the aircraft. The power dissipation will also rise
considerably, even if high levels of efficiency are achieved. The objective is to develop accurate and validated models
and tools to evaluate thermal issues and propose new cooling concepts related to Power electronics and EWIS in hybrid
electric propulsion. Both power electronics and EWIS face new challenges when introducing hybrid or full electric
propulsion in modern aircraft. In work packages 4 and 5 new concepts that are compatible with such new challenges
are defined, down selected and evaluated. To support these concepts, thermal models will be developed or updated, and
new cooling solutions will be developed. In addition, EMC mitigation means will impact the system thermal behaviour
and also the overall physical dimensions (e.g. size and weight). Therefore, thermal modelling and appropriate cooling
solutions are needed in order to minimize the footprint of the aircraft electric propulsion system. This work package
will use the system architecture and the characterisation of new signals and systems obtained in WP1. The models that
are developed in this work package will at its turn be used in designs and evaluations of new concepts in work packages
4 and 5.
To develop new conceptsfor dealing with power electronics generated EMI in aircraft electric systemssupplying hybrid/
electric propulsion. Power levels required for hybrid propulsion create new requirements for EMI in an aircraft. To
address those requirements new solutions must be developed. These solutions should adequately mitigate the EMI levels
to safe values while minimizing the impact over the electrical system in terms of size/weight and efficiency. Currently
accepted EMI standards like DO-160 apply an electric magnitude range that does not cover the magnitude range that
hybrid electric propulsion requires. In addition, the electric system architecture supplying the propulsion system differs
from previous practices. The involvement of power electronics in the EMI problem comes from both the source and also
as a possible mitigation means, e.g. active filters. This work package will use the aircraft and requirements definition
from WP1 to delve into definition of new electronics concepts within the specified architecture to deal with EMI,
while incorporating the thermal interactions and considerations derived from WP5, and will leverage models and tools
developed in WP2 and WP3.
To acquire interconnection technology suitable for high power, high voltage and, high current with low EM-radiation
and limited impact to cabin temperature
The objective is to achieve an overall optimal solution for the aircraft with hybrid/electric propulsion. In order to achieve that goal,
system architectures for various types of aircraft will be proposed; these being sport and regional. Then the architectures
will be traded-off and optimized for the different aircraft types. While WP4 & WP5 will focus on solutions for power
electronics and cables that are the aircraft electrical system major source and propagation paths for EMI, respectively;
and WP2/WP3 on the EMC/thermal modelling and management; this WP6 will integrate those solutions with the rest
of the aircraft electrical system including generators and propulsion electric machines, batteries, and the rest of the
non-propulsion electric system. The interactions along the integration process are expected to impact the individual
solutions and some degree of iteration of the component/system solution is expected before reaching the overall optimal
This WPis divided into three tasks focused on assessing of the project’s outcome from three different perspectives.First
task is focused on assessment of technological aspects of the developed systems and concepts with respect to defined
requirements (EMC, thermal, operational) and aircraft types. Second will investigate and assess possible economic
benefits and impacts coming from application of all the solutions and discuss achieved results from H2050 targets
perspective. The last task is going to evaluate final technological maturity of developed technologies and concepts and
propose next steps in their future development.
