Purpose and goal
The focus is on the aerodynamic and aeroelastic properties of an axial compressor stage subjected to non-uniform inflows. In the project, inlet disturbance screens will be designed & manufactured. These will first be tested experimentally to verify that they generate the intended disturbance pattern. The screens will then be installed upstream of an axial compressor stage to study how the inflow distortion affects the compressor aerodynamic and aeroelastic properties.
Expected effects and result
Experiments conducted on the impact of inlet distortion on compressor stages within this project provide valuable insights into flow behavior under non-uniform conditions. These studies enhance the fundamental understanding of aerodynamic performance, stability limits, and efficiency losses in compressors. The outcomes contribute to developing advanced design methodologies and predictive tools, supporting more robust and reliable turbomachinery systems in complex operating environments.
Planned approach and implementation
The project runs from 20 May 2026 to 20 May 2028 and includes five work packages (WPs). WP1 covers project management. WP2 focuses on defining inlet-distortion patterns by GKN. WP3 involves manufacturing and testing distortion screens at KTH. This is a check if distortion screens follows the design intent. WP4 integrates the validated screen upstream of a compressor stage at Stuttgart University. WP5 covers data collection, analysis, and interpretation of results.
