124156 - Performance Modeling and Analysis of Hydrogen-Fueled Aero-Engines 

With the global call for carbon neutrality, hydrogen-fueled aircraft engines, as zero-carbon emission solutions, are attracting significant attention. However, most hydrogen-fueled aircraft engine configurations face challenges such as being overweight, overly complex systems that make engineering implementation difficult, and the risk of exceeding NOx emission standards.

To address this issue, this paper surveys ongoing global research programs and advances in hydrogen-fueled aircraft engines. By analyzing their typical performance configuration, a simulation platform was developed for the performance analysis of hydrogen-fueled engines. This platform includes accessory modules specific to hydrogen-fueled engines and their control systems, such as hydrogen fuel modules, hydrogen regulation valve modules, hydrogen fuel pipeline modules, hydrogen fuel heat exchanger modules, and combustion chamber backfire warning modules. This simulation platform can be used for preliminary configuration selection and performance optimization.

Using this platform, the paper analyzes the differences between hydrogen-fueled aircraft engines and traditional aviation kerosene engines and conducts performance analysis and comparisons of different hydrogen-fueled engine configurations announced by various schemes, paying particular attention to key performance parameters such as cycle thermal efficiency, overall efficiency, thrust-to-weight ratio, TSEC, NOx emissions, etc.

Based on these detailed simulation analysis results, the paper deconstructs and rebuilds the announced configurations, proposes a new structural scheme for hydrogen-fueled turbofan engines, and conducts simulation comparisons with existing configurations. Finally, the paper provides a forward-looking outlook on the future development trends and overall design of hydrogen-fueled aircraft engines.

This research helps deepen researchers' understanding of the potential and challenges of hydrogen-fueled aircraft engines, provides references for their future design and optimization, and provides an effective platform for the design and controller verification of hydrogen-fueled aircraft engine control plans.
