Single Sector Combustor

The test combustion chamber is designed for use with a variety of gaseous and liquid fuels. These include conventional fuels such as kerosene, as well as sustainable fuels such as hydrogen or Sustainable Aviation Fuels (SAF). Furthermore, the EDS allows for precise and independent adjustment of the parameters air pressure, inlet temperature and mass flows, enabling the test rig to simulate realistic thermodynamic conditions found in modern aircraft engines and gas turbines.

By using the laser-optical measurement techniques developed at the Institute, flow fields, temperature distributions, reaction zones and soot-formation processes can be recorded non-invasively and in high resolution during the tests and subsequently analysed. The test rig is optically accessible from three sides and can be optimised on request for analyses of the combustion chamber walls. The measurement section containing the burner is mounted on a three-axis traverse table, which allows it to be moved in all three spatial axes. This ensures a robust, static configuration for the laser diagnostics, enabling the precise investigation of the various areas of the reaction zone. This straightforward and static configuration is a particular advantage, especially for the testing and development of new, often combinatorial, measurement techniques, and offers a unique selling point in terms of the approximation of realistic conditions.
