Periodic Reporting for period 2 - SMR ACAP (SMR aircraft architecture and technology integration project)
Reporting period: 2023-07-01 to 2024-06-30
The top-level objectives of the ACAP project will be the following:
- Provide to the SMR Clean Aviation community a collaborative framework, associated with a digital backbone approach, to enable the integration at aircraft level of the key identified technologies;
- Define the top-level requirements of the ultra-efficient and H2-enabled aircraft concepts, and cascade the target settings to the subsystems addressed in the parallel SMR pillar projects;
- Definition of absolute environmental targets or thresholds based on the planetary boundaries framework and other biogeophysical limits and the corresponding environmental breakdown on component and system level
- Management and establishment of central CA-SMR Life cycle inventory based on Clean Sky 2 - Eco Design activities and integration of Maintenance, Repair and Overhaul Data as central SMR Data Source for LCA work.
- Execute baseline LCA (mainly based on qualitative Data as Flow Charts, Design & Technology concepts, Bill of Processes and Materials etc) and Compile 1st issue of LCA results based on existing LCI datasets and result communication towards Demo Projects.
- Development of Environmental Co-Design approach for application in CA-Key technology demonstrators
- Identify the most promising technologies to be integrated in the future greener SMR, with a special focus within ACAP on the definition of relevant systems associated to propulsion and non-propulsive functions;
- And finally conduct the trade-off and down-selection of the most promising aircraft configurations with ultra-efficient airframe, both for SAF and H2-enabled energy carrier, up to a “pre-PDR” definition level of the aircraft, and including final impact monitoring.
During that quartal, the ACAP project delivered the bricks specification and architecture Trade for PE/NPE system. The Integrated Platform NEXTGEN LAB performed several releases.
The SMR ACAP project organised technical alignmeent meeting within the SMR Pillar, and presented the the initial Architecture Options for Ultra-Efficient Aircraft and the Initial H2-Enabled Concepts. The Impact Monitoring Committee kicked off, with strong involvement of ACAP. Furthermore, the ACAP Impact Monitoring provided the IM yearly report.
Activities around the LCI and LCA progressed with the delivery of the exploitation Plan for the Aerospace LCI database, and the kick-off of LCI / LCA with focus on CA-Demonstrator Project results
At the Clean Aviation Annual Forum and ILA Berlin airshow, some of the ACAP highlights could be displayed.
The HG metrics and IM process were provided with D5-1 deliverable, which was analysed and integrated into an updated version. This version was merged with the D5-2 2023 Yearly Report and was delivered on 22.12.2023.
The ACAP project participated in the EC Workshop on aviation non-CO2 emissions on 13+14.12.2023 in Brussels and presented a comparison of “Clean Sky 2 Technology Evaluator and Clean Aviation ACAP Impact Monitor”.
In several discussions between engine specialists from DLR, Airbus and the engine manufacturers, an agreement on reference aircraft for non-CO2 en-route emissions has been found. While there is a good match for NOx and nvPM particle number, some uncertainties remain for the nvPM particle mass. This will need further monitoring.
The WP5 created a detailed planning for the 2024 M23 deliverable including detailed contributions from the partner projects including workshops with OFELIA, SWITCH and HEAVEN. This planning was revised and will be updated in the aftermath of the repositioning of the configurations that became necessary with the re-assessment of confidentiality of data.
