The findings are then further investigated for transferability for transient flows at the LSRC. For this purpose, stationary measurements are carried out on the cascade wind tunnel. To investigate fouling, representative fouling topology blade geometries are created and studied both experimentally and numerically. The deposits increase the surface roughness of the blades and change their geometry. Fouling refers to the deposition of small (~ 2 - 10 µm) particles (eg smoke, oil or salt) from the ambient air on the compressor blades. ![]() The IFAS specifically investigates the fouling of the compressor. Therefor an understanding of the essential mechanisms of action is necessary. Maintenance tailored to the engine requires models that can predict the performance of an engine within an operating cycle, depending on the mission. Periodic maintenance of the engine can partially reverse the closure. This reduces the performance of the engine and thus the efficiency. ![]() During operational use, an aircraft engine wears out. ![]() Faculty of Electrical Engineering, Information Technology, PhysicsĪnother project alongside the interpretation of new parts is the operational wear of gas turbines and its components and parts.Architecture, Civil Engineering and Environmental Sciences.The University Development Initiative 2030.Language and intercultural competence training.Discontinuation and Credentials Certification.
