Computational dynamics of an elastic airplane
Chudý P., Daněk V.
pages 137 - +8p., full text

This paper presents the work performed by the Institute of Aerospace Engineering, Brno University of Technology. Purpose of the project was to compare the results obtained from classical analytical solutions and a complex numerical simulation of airplane's aeroelastic response. Compared to the analytical solution, which reduces the entire process to a straightforward manipulation with time proven graphs and tables, the numerical simulation offers a more complex description of the investigated dynamic processes. A complex simulation, in contrast to the analytical solution providing us with only one estimated parameter, allows monitoring selected quantities in the time domain thus, giving us a tool for a visual qualification of the investigated process. In the past, dynamic aeroelastic properties have been estimated utilizing simplified stick beam models. The desire for more complex aeroelastic simulations led to the concept of advanced aeroelastic model coupling advanced 3D structural FEM models with proven aerodynamic theory in the form of DLM panel Metod. 1
