Hydrogen Engine Architecture Virtually Engineered Novelly

The "HEAVEN" project, formally titled "Hydrogen Engine Architecture Virtually Engineered Novelly," aims to advance climate-neutral aviation through the use of alternative fuels such as green hydrogen and Sustainable Aviation Fuel (SAF). Coordinated by Rolls-Royce Deutschland Ltd & Co KG, the project started on January 1, 2023, and will run until December 31, 2026, with a total budget of €35.64 million, of which €29.91 million is funded by the EU under the Horizon Europe program.

Key Objectives:

1. UltraFan H2 Development: The project seeks to evolve the UltraFan engine architecture into UltraFan H2 by improving gas turbine efficiency through the use of hydrogen and hybrid-electric technology. This aims to achieve a 20% reduction in fuel burn, contributing significantly to the decarbonization goals of the Clean Aviation Strategic Research Innovation Agenda (SRIA).
2. Enabling Technologies: Incorporate innovative enabling technologies at TRL3 to enhance gas turbine efficiency. The goal is to validate the UltraFan H2 design up to TRL6, supporting its entry into service by 2035.
3. System-Level Requirements: Capture and mature system-level requirements for short-medium range (SMR) propulsion, including operational and maintenance needs.

Expected Impact:

• Efficiency Improvements: The project aims to reduce fuel burn by 20%, significantly lowering greenhouse gas emissions and supporting the European Green Deal's climate-neutral targets.
• Technology Validation: Validate novel gas-turbine technologies, advancing them to TRL6, which will pave the way for future hydrogen-powered aircraft.
