hallstaTt - TEC modifications to reduce noise emissions with special consideration of NDT-rotor blade vibrations

Project: Research project

Project Details


Within this project different modifications of the turbine exit casing will be applied in order to reduce noise level and their effectiveness is evaluated. Some of these modifications (e.g. absorber-blades) are altering surface roughness, thus affecting boundary layer development. Therefore, the project is considering blade excitation of the upstream rotor (due to altered potential effects) as well a change in aerodynamically losses. Most important outcomes of the project are suggestions and recommendations how to reduce noise level of aero engines considering aeroelasticity in order to perform a holistic optimisaton.
