WORK PERFORMED & MAIN ACHIEVEMENTS

In 2023, HECATE finalized the top-level requirement definition moving to the design and prototyping phase of the technology bricks towards a TRL4 maturation. The setting and requirement phase defines the tools for efficient collaboration between partners and the baseline requirements that will define the architecture and the design of the technology bricks. During this first period, HECATE has achieved the next key milestones:

• The definition of the top-level requirements and the electrical distribution architecture.
• The definition of a validation and verification strategy towards the final validation in a test bench (copper bird) at the end of 2025.
• The definition of interactions with other Clean Aviation programs.
• The implementation of tools, mechanisms, and rules for the collaboration of all partners. With both a legal framework defined, and an operational process outlined.

During 2024 and after finalizing the top-level requirement definition, HECATE has successfully conducted all Preliminary Design Reviews for its different technology bricks. The efforts during the year were centered around the final design and prototyping of the technologies that form the electrical architecture with a focus on preparing and conducting all Critical Design Reviews towards the testing phase.

The project is now progressing to the integration of its different components where the technology bricks will be tested in junction, achieving a TRL5 electrical architecture capable of addressing the needs of future hybrid-electrics platforms by the end of 2026.

During the second year, HECATE has achieved below milestones:

• PDR passed for all technology bricks under HECATE architecture.
• Critical design review conducted for Primary Distribution, Power Management and Secondary Distribution.
• Progress on the Electrical Architecture Digital Twin by finalized digital models of the different technology bricks.
• Initial batch of cables capable of addressing the high voltage requirements successfully manufactured.
• Initial scalability studies on HECATE technologies towards different platforms.
• Ad-hoc review passed, testimony of project progress towards its objectives.
