Abstract: [slo] [eng]
Diplomová práca sa zaoberá problematikou trepotania, ktorá v letectve predstavuje jeden z najnebezpečnejších dynamických aeroelastických javov. Práca obsahuje postup tvorby a následnú analýzu trepotania dvoch MKP modelov krídla experimentálneho lietadla VUT 051 Ray. Cieľom práce je porovnať jednotlivé MKP modely a určiť kritickú rýchlosť trepotania, zhodnotiť efektivitu a využiteľnosť MKP modelov pomocou 1D a 2D elementov. The diploma thesis deals with flutter, which is one of the most dangerous dynamic aeroelastic phenomena in aviation. The work includes the creation process and subsequent flutter analysis of two FEM models of the wing of the BUT 051 Ray experimental aircraft. The goal of the work is to compare individual FEM models and determine the critical flutter speed, to evaluate the effectiveness and usability of FEM models created by 1D or 2D elements.
Keywords: aeroelasticity; airplane; critical speed; FEM; flutter; wing
