Original abstract
This paper presents the work performed by the Institute of Aerospace Engineering, Brno University of Technology. Project’s main purpose was to compare the results obtained from complex numerical simulation and analytical solutions of airplane’s aeroelastic response. Numerical simulations provide a complex description of the analyzed dynamic processes and monitoring of selected quantities in the time domain. This represents a tool for a visual qualification of the investigated process. Utilization of a simplified beam-stick model represents an industrial standard in the field of computational aeroelasticity/flight mechanics. The need for complex aeroelastic simulations leads to a concept of an advanced aeroelastic model that integrates advanced 3D dynamic part (model) with proven aerodynamic theory.
Czech abstract
Ve srovnání s analytickým řešením, vedoucím na odhad pouze jednoho parametru a redukujícím výpočetní proces na vstřícnou manipulaci s časem ověřenými grafy a tabulkami, poskytuje numerická simulace více komplexní popis zkoumaných procesů a monitorování vybraných veličin v časové doméně. Požadavky na komplexnější aeroelastické simulace vedly na koncept aeroelastického modelu spojujícího pokročilé 3D strukturní modely s ověřenými aerodynamickými teoriemi ve tvaru metody dipólových sítí.
