GE Aviation participates in the MUSIC-HAIC project with its Munich-based Advanced Aviation Technology (AAT) Centre.
GE Aviation, headquartered in Cincinnati, OH U.S., that in Europe comprehends 12,500 people, spread across 17 production and R&D sites, is heavily involved in the Clean Sky European programme to develop new technologies for the next generation aero-engines.
AAT is part of the GE Aviation global team, with strong contributions to the development and sustainability of commercial engines, from large turbofans to small turboprops, in both GE internal and joint research and technology programmes, as well as in aircraft engine product turbomachinery design of next generation aero-engines, e.g. leading 3 Clean Sky core partner projects.
The AAT team develops and validates the newest technologies with an emphasis on commercial engines that will be in service by 2030 to 2035. Since its foundation, the team has contributed to the new generation engine programs such as Passport 20, LEAP, GE9X, and GE Catalyst, with focus on high Technology Readiness Level areas.

Role in the project

The GE’s 100 year long and broad in-service experience in icing conditions, including ice crystal icing, has provided a wide range of successful service experience and data, but next generation turbofan architectures may affect the icing threats to the engine, therefore well-established existing analysis tools need to be shown to be applicable or modified for new turbofan architectures. Also, various hybrid propulsion architectures under study may generate even more complex inclement weather threats.
Hence further advanced researches in the intricate mechanics and thermodynamics of ice crystals interaction with aero-engine components, spanning gas, liquid and solid phases, are highly sought by the whole aviation industry.
GE Aviation leads the WP3 development and preliminary assessment of 3D simulation tools. GE aims to define the multi-physics and analytical requirements for the numerical models in conjunction with the other engine manufacturers, with strong focus on right accuracy, computational time and validation strategy, in order to generate numerical tools directly applicable to aero-engine design. GE will also provide the definition of the rig test conditions in order to guarantee that the test environment is representative of real flight engine conditions, and where some in-flight parameters cannot be exactly replicated in the laboratory, GE intends to generate scaling laws to close the gaps associated to the ground vs. in-flight differences.
GE will lead the preliminary assessment of the 3D newly generated tools with real engine test cases and will be involved through the whole validation process until reaching a final technology readiness mature level, corresponding to an industrial standard TRL6.
