Abstract
Paper presents results of dynamic FSI simulation of unmanned aerial vehicle, where for first case, a typical linear material was used, and for second case, a composite material was used. The simulations were performed with the objective of studying model reaction with forces indicated by flow which were defined by initial conditions. Secondary objective was to evaluate critical flutter speed. Simulations provided interesting results: for linear case, applied flow speed resulted with occurrence of flutter phenomena, while composite case exhibited damping of vibration in designated points along the wing. Presented simulations were performed within an environment using loosely-coupled approach. CFD simulations were carried out with use of parallel code DLR-Tau. FSI computations were executed with applied modal approach for structural model and full data exchange between fluid and structure as well as mesh deformation.
