Abstract

V magistrski nalogi so predstavljena priporočila za snovanje varnega letala odpornega na vertikalni trk. Sestavo letala smo razdelili na tri glavne komponente namenjene absorpciji energije v primeru vertikalnega trka: sedež, struktura trupa in podvozje. Za vsak del posebej je bila izvedena eksplicitna časovno odvisna numerična simulacija v programskem paketu Abaqus/Explicit. Iz dobljenih rezultatov smo med seboj primerjali pospeške, ki delujejo na telo potnika ter sile in pomike strukturnih delov, iz katerih se vidi količina absorbirane energije. Na koncu smo izvedli še računalniško simulacijo sestave generičnega letala, ki je vsebovalo vse zgoraj naštete komponente.

Secondary title: Numerical simulation of a hard landing for a VTOL aircraft
Secondary abstract: The master thesis describes recommendations for crashworthiness design of a VTOL (vertical take-off and landing) airplane. The composition of the aircraft was divided into three main components designed to absorb energy in the event of a vertical crash: the seat, fuselage and landing gear. For each part, an explicit time-dependent numerical simulation in Abaqus/Explicit was performed. From the obtained results, we compared the magnitude of accelerations that work on the body of the passenger and the force-displacement correlation of the structural parts from which the amount of absorbed energy can be calculated. At the end, we also carried out a computer simulation of the generic airplane composition, which included all of the above components.
