1. Aeroelastic Concepts for Flexible Aircraft Structures
Abstract : In this thesis, aeroelastic concepts for increased aircraft performance are developed and evaluated. Active aeroelastic concepts are in focus as well as robust analysis concepts aiming at efficient analysis using numerical models with uncertain or varying model parameters. READ MORE

2. Generalized Methods for Aeroelastic Analysis
Abstract : Generalized aeroelastic methods are here defined as methodsthat allow aeroelastic analysis of problems in many engineeringdisciplines. Aeroelastic/fluid-elastic phenomena are ofsignificant importance in many industrial applications, but fewtools exist for efficient analysis of these systems. READ MORE

3. Aeroelastic Concepts for Flexible Wing Structures
Abstract : This thesis summarizes investigations performed within design, analysis and experimental evaluation of flexible aircraft structures. Not only the problems, but rather the opportunities related to aeroelasticity are discussed. READ MORE

4. Sensitivity of Aeroelastic Properties of an Oscillating LPT Cascade
Abstract : Modern turbomachinery design is characterized by a tendency towards thinner, lighter and highly loaded blades, which in turn gives rise to increased sensitivity to flow induced vibration such as flutter. Flutter is a self-excited and self-sustained instability phenomenon that may lead to structural failure due to High Cycle Fatigue (HCF) or material overload. READ MORE

5. Design, Optimization and Evaluation of a Transonic Aeroelastic Rig
Abstract : The compressor is one of the most essential components of a modern turbomachinery engine. This component is exposed to vibrations that without proper design can damage structural integrity and lead to failure. READ MORE
