As described in the 4th Call for Proposals (CFP04) entitled Electrical simulation model identification method and tool (JTI-CS2-2016-CFP04-SYS-02-24) the System ITD of Clean Sky 2 aims to contribute to aircraft weight and environmental footprint reduction. Among the systems, equipments and functions contributing to these environmental objectives, the more electrical aircraft technologies are key elements. The maturity of these technologies will be assessed in System ITD in local test benches and integrated demonstrators.

For electrical systems, comprehensive validation and verification activities are mandatory to demonstrate substantial performance. Indeed, by correlating performances and design margins of both network and equipment, aircraft manufacturers ensure safe and reliable operation: any sub-system not complying with its specification requirements may lead the network exceeding its operating limits, further leading to improper operation and additional failure. Moreover, the mastery of design margins is a key lever to improve performances and optimize weight at system and aircraft level.

In Clean Sky 2 System ITD, WP5.0 focuses on Aircraft Electrical Architecture. Definition and validation of the electrical network, including core electrical equipments, will be done in a complementary way by simulation studies and demonstration of equipment and network operation on a test rig. An adequate simulation platform, including accurate and robust model library and advanced post processing tools, is required to reach simulation V&V goals.

In previous aircraft programs and research project, SABER simulation software has demonstrated its suitability to fully support aircraft electrical network V&V process. SABER RD robust generic electrical model libraries have been developed to be used as a baseline for specific model development. However, experience from these previous projects shows that the availability of accurate models can be late in the project, taking a slice out of the full simulation contribution potential for V&V activities.

Hence, the aim of this project will be to provide the capacity to adapt generic models to fit real hardware from experimental measures and/or design data. Model fitting methods selection and development will have to be performed for each phase of equipment development, that is to say from design to hardware validation.
