Submitted paper deals with aeroelastic simple beam computational models, so called stick models. Stick models are simple, effectively usable and suitable for variation of parameters or for updating according experimental results. Therefore, stick models are ordinarily used for aeroelastic analyses. However, in some specific cases, special elements or modelling patterns must be used. Paper describes special modelling techniques, namely 1) Model of control surface and tab without stiffness parameters, 2) Common model of symmetric and antisymmetric vibrations for control surface and tab flapping modes and, 3) Common model of symmetric and antisymmetric vibrations for twin-engine aircraft engine vibration modes. These techniques are demonstrated on the example the full-span stick model of a twin turboprop commuter aircraft.
