The department laboratories include several combustor test rigs for combustion research and industrial investigations. The test rigs are designed to integrate realistic combustor configurations with optical access for visual and laser-based analysis of combustion processes at realistic engine conditions.
The department can rely on long-standing experience in the development and design of new experimental prototypes with optical access for combustion test facilities. Innovative manufacturing techniques are provided by the DLR Sytemhaus Technik and allow reliable test operation for the typical high-temperature and high-pressure range. The department operates a range of test rigs where advanced diagnostics are developed and applied (in cooperation with the Measurement Techniques Department).

(High Pressure Combustor Test Rig 1)
The HBK1 provides the infrastructure for several single sector and multi sector combustor test sections. The high-pressure combustion test facility allows a detailed investigation of the combustion process with laser-optical measurement techniques under real engine operating conditions.
(Single-Sector-Combustor Test Rig)
The SSC is a combustion test rig with optical access to the primary zone on three sides. It is especially suited for the investigation of the burner’s near field with laser-optical measurement techniques.
(Optical High Pressure Atomization Test Rig)
The OHA is designed to operate under high pressure, temperature and velocity conditions, approximating the values found in actual gas turbine combustion systems. The Test rig is fully equipped to perform the measurements on sprays and mixing of air and fuel, under non-reactive conditions.
(Atmospheric-Primary-Zone Test Rig)
The test rig allows the integration of several test sections for the investigation of spray atomization, cooling and combustion processes under atmospheric pressure.
