Quantification of Modeling Uncertainty in Aeroelastic Design

Evaluation and Uncertainty Quantification of Bifurcation Diagram: Landing Gear, a Case Study

“…SA has two main features: it describes how variations in the output can be caused by variations in factors and it analyses which kind of influence the factors have on the system; it does not identify which are the causes of particular outputs. The SA has a significant role in the increment of the level of confidence of a model, a problem raised from the presence of uncertainty, which can be model (form), parametric (aleatory and epistemic) and/or predictive [12]: SA is directly correlated to and is a means to cope with the uncertainty.…”

“…It is for this reason that in a preliminary design, the analyses are done through the use of simulators, especially in the presence of complex dynamics and/or structures for which experiments can be very time expensive and/or impracticable. In the last decade, researchers have been starting to look at the effect of parametric uncertainty in the structural parameters and in composite structures in the flutter occurrence and in the amplitude and frequency of LCOs, arising beyond the linear flutter speed [5] [12].…”
