Original abstract
The detailed topometry optimization of the critical part of an aircraft wing is presented in this article. The integral lower wing structural panel of aircraft in the Commuter category of the CS-23 regulation standard is selected for optimization. The first case demonstrates significant weight savings using modern Finite Element (FE) optimization methods for determined structural constraints. A practical aircraft operation and additional regulation requirements affect optimization constraints in the second case. This detailed optimization also consists of FE model validation, stress analyses and complex load capacity analyses, which are necessary for designed structural modifications with an optimal stress distribution.
Czech abstract
Současné Výzkum se zabývá speciálních hybridních spoje kovov-kompozit, které používají tenké plechové výztuže s malými kolíky (2-3 mm), zasazene do kompozitní části spoje. Tento technologický trik významně a pozitivně ovlivňuje pevnost šroubových spojů kov-kompozit zatížených v příčném směru. Tato skutečnost byla prokázána porovnáním výsledků únavových zkoušek (na vytáhovani šroubů) spojů kovov-kompozit s a bez výztuže.
