This paper describes a detailed flutter analysis of fan casing contour modifications on a scaled high-speed fan to investigate the influence and effect on flutter boundaries. The flutter analysis focusses on discrete selected members from a previous multidisciplinary study of an automated aero-acoustic optimization with respect to the overall engine performance. The aerodynamic baseline performance...
Aircraft propulsion will continue to rely on gas turbine technology for the next decades to come. Thus, to achieve environmental agreements, ensure engine safety, and retain economic competitiveness, ongoing development with a multidisciplinary design approach is indispensable. In the present study, the multi-criteria analysis of the fan, a decisive component in modern aero engines, is examined. In...
The goal of plasma induced healing is to obtain a high bacteria killing rate without significant damage of the healthy cells. For this task various cold atmospheric pressure plasma jets (APPJ's) have been developed over the years. In those APPJ's the plasma is created with an inert gas inside a ceramic or glass tube between two electrodes. The effluent mixes outside with the air-environment. APPJ's...
