    <title language="deu">Fraktionale Ableitungen in der Modellierung für die Strukturdynamik</title>
    <abstract language="deu">Modellierung ist eine zentrale Fertigkeit, ein Modell ein Instrument, um beispielsweise Fragestellungen der physikalischen Akustik abzubilden, zu untersuchen und zu verstehen. Obwohl Modelle ganz unterschiedliche Fragestellungen in der physikalischen Akustik adressieren können, sind die zugrundeliegenden Modellierungsansätze und -philosophien häufig sehr ähnlich. Dieses wurde in dem diesjährigen Herbstworkshop des Fachausschusses Physikalische Akustik der DEGA am 22. und 23. Oktober 2021 im Physikzentrum Bad Honnef unter der Bezeichnung Modelle der physikalischen Akustik intensiv beleuchtet und diskutiert.</abstract>

    <title language="eng">Stability Analysis for an Ultra-Lightweight Glider Airplane with Electric Driven Two-Blade Propeller</title>
    <abstract language="eng">Safety is the most important requirement in flight operations. This also affects the application for an extreme lightweight glider in this paper. Essential properties are the target weight below 120 kgand the electric propulsion. The unsymmetric inertia from the two-blade propeller at the rear in combination with the light and flexible aluminium tube support makes it necessary to investigate the risk of mechanical instability. Starting from the equations of motion, the time-variant system matrices are set up. The simulation of Floquet multiplier and Hill’s hyper-eigenvalue problem provide the necessary information about the system stability. The conclusion is that the potential instability due to structural damping in the observed system can be avoided in the range of operation. The damping, experimentally determined by approximately 2%, is sufficient.</abstract>
