The objectives of the project are still scientifically and technologically relevant, in fact, they are critical topics for the future of aviation.
1.Investigating EMI filtering solutions with less volume and weight.
The filters are key to reduce a significant amount of weight from the converter to push the power density and reduce the footprint on the aircraft.
The KPIs set in the proposal have been achieved for filters dedicated to power conversion.
2.Investigating EWIS technologies with less radiated EMI, less volume and lower weight.
It is becoming clear in EASIER that power EWIS, busbars and connectors are main drivers of noise particularly on the high frequency. Identifying the EMC mechanisms is key to minimize the filtering effort. The thermal aspect of power feeders is key for electrification distribution to reduce the overall impact of the power feeders on the aircraft.
3.Improved heat transfer from electrical systems to the aircraft exterior.
This topic is extremely relevant. Improving heat transfer coefficients will lead to smaller systems. Identification of heat loads and their cooling will be continued thought efforts in Clean Aviation by some of the partners.
4.Optimization of the integration of electrical systems with significant mutual impact.
Architecture and analysis of the adds for the improved technologies is an important topic to understand the impact of technologies.
5.Engagement with airframers and regulatory agencies.
DO160-G, the standard defining procedures and environmental test criteria for testing airborne equipment, is considered as an outdated regulation when it comes analyzing EMI for power propulsion systems. On that note, discussion have been had with the Industrial Advisory Board, in particular with EASA, Airbus and Aeronamic to understand what things can be adjusted from the DO160-G to make it more relevant. Unfortunately, everyone in the IAB have concluded this is an effort that will be closed with the future regional and SMR definitions in the context of Clean Aviation.
Significant work is carried out in EUROCAE working groups, participation on SAEL conferences and other forums in order to identify the needs from a regulatory perspective that the new paradigm of electrified aircraft is pushing to the industry. This effort is a must to progress towards green aviation and zero emission aircraft transportation, as acknowledged by the EC through the definition of Clean Aviation and future programs in which many of the EASIER partners are going to be contributing to.
6.System trade-off analysis and technology identification.
System trade-offs and technology evaluation are a need to achieve an optimized solution not at component but at an aircraft level. This topic will also be continued in Clean Aviation.
7.Roadmapping of hybrid/electric aircraft key enabling technologies in terms of EMI and thermal management.
Identification of the impact of the key enabling technologies and know-how from EASIER is extremely relevant for future efforts within the aerospace industry to reduce GHG emissions.
The activities started in EASIER will continue thought internal efforts of the industrial partners and also within different projects in Clean Aviation to deliver solutions relevant for next gen SMR and HER.
