Hydrogen Combustion in Aeroengines

The goal set out in the European Green Deal to make civil aviation climate-neutral by 2050 necessitates intensive research into renewable fuels for use in aircraft engines.

 

Motivation and objectives

As a gaseous fuel, hydrogen offers a potential alternative to liquid synthetic fuels due to its high gravimetric energy density, CO₂-free combustion, and good integration into an increasingly sustainable energy infrastructure. In the European research project HESTIA (Hydrogen Combustion in Aero Engines), six engine manufacturers and 18 university partners are working to identify the combustion chamber-specific challenges of hydrogen combustion in aircraft engines and to develop a deeper understanding of these processes.

 

 

The ITV focuses on the design and experimental investigation of various hydrogen injection variants in order to achieve the most stable and robust flame stabilization possible. The investigations are carried out using modern laser spectroscopic measurement methods and established exhaust gas analysis technology in order to record the flame behavior in detail in an iterative design process and to further develop the selected concepts in a targeted manner.

 

Subproject

Single-burner test rig

The project investigates injection strategies for hydrogen combustion and their influence on stable, low-emission engine flames.

 

Responsible institute

The project is managed by the Institute for Institute for Turbomachinery and Fluid Dynamics.
