Original Abstract

The paper deals with the fatigue evaluation of nose and main landing gear of the VUT 100 Cobra airplane based on results of the FEM stress analysis. The main goal is to determine the stress levels ensuring the requested undercarriage safe life and establish the preliminary life value before starting the fatigue tests. A realistic random sequence of flights and loads within is applied in the fatigue analysis considering essential service load conditions. The fatigue calculation itself is realized by the FEFAT module of the MSC.Fatigue software. The fatigue analysis has provided the first evidence of possibility to reach the requested safe life, an overview of critical locations of structure and recommendations for design improvements.
