Single cup test campaigns conducted at ETHZ, results in D1.11.
Tunable Combustion Acoustic test at Cosvig/SestaLab, results in D1.37 and D1.2 MS1.8.
Pressure Sensitive Paint test at UNIFI to study film cooling effectiveness, results in D1.6. InfraRed atmospheric reactive test at UNIFI.
High Pressure Sector test at DLR completed.
Altitude relight test campaign preparatory activity.
Full Annullar test campaign preparatory activity.
Additive manufacturing trials on low NOx Injection systems have started at GE AVIO. Preparations for Low NOx single-cup combustor tests in 2025 at DLR Cologne and ETHZ started.
WP2 – H2 Engine Fuel System
he H2 Engine fuel system design and specifications activities performed during first half of year 2024 have been performed as part of TROPHY project. The second half of year 2024 was dedicated to activities in preparation of the Concept Review (final) for a ground Wet Rig configuration, MS2.5. This result contributes to the High Level Objective n°1 “De-risk, mature and test the key sub-systems of an hydrogen direct-burn engine” and allowed reaching TRL2 on the H2 Engine Fuel System.
Delivery of H2 Engine Fuel System installation study at wet rig (D2.53).
All along the Year, the partners conducted their development plan for their equipment and support Safran AE to:
o Provide all updates to support the GAM amendment proposal
o Close concept technical studies at engine level for Flight configuration
o Support the physical installation/integration for the ground wet rig
o SEFS preliminary design for the nominal operational case
WP3
Concept Design Review including H2-enabling modules assessment and verifications on existing P20 donor engine component achieved.
Definition of contents for the Preliminary Design Review (PDR) on CDN structures, outlining the means of demonstration of design requirements at PDR level
WHR technology maturation – preparation of component test.
Control system and engine integration activities, Electrical system definition, Control and Actuation System design
WP4 – Ground Testing
As a result of 2024 replanning, the present work package is discontinued after M18, preserving preparatory work instrumental for the future GTD campaign, which has been object of deliverables D4.1 and D4.2.
WP5 - Propulsion Integration:
• Systems Maturation Logic: Progress on the definition of the overall End-to-End Fuel and Propulsion System, with preliminary concept defined and risks & opportunities assessment.
• H2 Sensor Development: Development and testing of a proof-of-concept fiber optic hydrogen sensor.
• Thermal Protection and Sealing Systems: Fire and cryogenic tests on sealing and insulating systems.
WP6 - Contrails Assessment and Tools Development:
• CFD Modeling: Creation and convergence of Computational Fluid Dynamic model at hydrogen combustion conditions.
• Contrail Formation: Investigations into dominant nucleation pathways and the role of lubrication oil in contrail formation.
WP7 – Demo vs Product gap studies
Creation of Project Interface Document (PID) for EASA.
Gap analysis on CS-E ongoing.
