Keywords: aeroengine, lean combustion, optical combustor, laser measurements

The combustor enables the optical investigation of unscaled burners for lean combustion in aeroengines. The maximum operating condition is 2.3 kg/s air mass flow through the combustor liner at 900K preheat and 20bar inlet pressure. The combustor volume and cooling are as close as possible to engine conditions.
