An experimental and numerical study has been conducted to evaluate the parameter of a CO2 dry ice cleaning process for the compressor of a jet engine. The cleaning process itself should be later on able to achieve a substantial increase of the EGT margin, going along with a reduction of the fuel flow. In contrast to the current usage of CO2 dry ice as a detergent in the part cleaning process, the targeted method should allow the cleaning of the compressor, while the engine is on wing and the service openings are left closed. The experiments have been conducted in a test rig, which allows the motoring of the compressor with an electrical engine. The accompanying simulation work has been performed to allow a deeper insight view of the flow and CO2 particle behaviour in the compressor. First results indicate that a cleaning effect is possible up to stage 6 of the high pressure compressor. Further work is necessary to intensify the cleaning, which should help to loosen also contaminations with a high adhesion and to increase the areas within the compressor, which are subject of the cleaning process.
