Abstract: 

This paper presents a simulation-based investigation of shape-adaptive structural concepts for inlet guide vanes in axial turbo compressors, utilizing LS-DYNA for structural analysis under aerodynamic loads. Instead of rotating rigid blades, a new concept based on a segmented kinematic chain enables controlled trailing-edge deformation of up to 50°, facilitating flow-optimized guide vane profiles. Parametric modeling plays a central role in defining both the skeletal structure and the adaptive surface layers. Using a combination of geometric parametrization, kinematic modeling, and implicit finite element simulation, the study analyzes stress distributions, displacements, and contact forces for both structural segments and the deformable skin layers. The results highlight the feasibility and robustness of the shape-adaptive approach, laying the groundwork for subsequent experimental validation.
