Updating of Dynamic Model of Aircraft Structure with Wing Tip tanks According to Results of Ground Vibration Test
Original language description
This paper discusses the updating of dynamic stick model of aircraft structure according to results of ground vibration test. The paper is focused on the model of aircraft with wing tip-tanks, which is specific by multi-mass configurations, given by the fuel load in both main tank and tip-tanks. The paper outlines the approaches of flutter analysis as regards to ground vibration test results. Then, the theoretical background of methods of updating including Bayesian parameter estimation and more generic optimization using powerful nonlinear gradient-based methods are given. Finally, the application of the former method on the commuter aircraft for 19 passengers with wing tip-tanks is described. Selected results are shown, evaluated and the conclusions are formulated.
