AIRCRAFT MODEL UPDATING ACCORDING RESULTS OF GROUND VIBRATION TEST
Original language description
This paper is focused on the updating of aircraft structure computational model according to the results of ground vibration test. Subjected model is used for aeroelastic analyses, in particular for flutter analyses. First, the applicable approaches of flutter analyses are outlined. Next, the theoretical background of commonly used Bayesian parameter estimation technique of model updating is provided. After that, the methodology of model updating adjusted for aircraft structures is described. Finally, the methodology is demonstrated on the example of the twin engine turboprop commuter aircraft for 19 passengers. Selected results are shown, evaluated and the conclusions are formulated.
