A joint effort was conducted by an aeroelastic team in the Applied Vehicle Technology of the NATO Science and Technology Organization, working group AVT-191 "Application of Sensitivity Analysis and Uncertainty Quantification to Military Vehicle Design". The team investigated the applicability of various sensitivity analysis and uncertainty quantification approaches to a case for an aeroelastic wind tunnel model that was designed and tested from which a significant database was obtained for both static aeroelasticity and flutter. Presented in this paper, is an overview of the aeroelastic team efforts documented in the AVT-191 final report (Ref. 1), including the investigation that was conducted for determining and accounting for uncertainties associated with modelling the static aeroelastic characteristics of the S4t wind tunnel model. In addition, various uncertainties and anomalies noted in the measured model deflection data were investigated as an important aspect of correlations with the analytical modeling results. The problem was caste as an investigation to address uncertainties in aerodynamic models, structural models, wind tunnel test conditions as well as the processing of test data.
