Three-parameter uncertainty quantification for generic missile FG5

This paper summarizes the results of international collaborative work on applying numerical methods for uncertainty quantification to a generic missile configuration. This work was conducted as part of the NATO STO Task Group AVT-191 on Application of Sensitivity Analysis and Uncertainty Quantification to Military Vehicle Design. Three different CFD codes are used by the three partners to compute and compare the nominal flow around the FG5 missile for which experimental data is available before moving on to estimate the statistics in output quantities of interest due prescribed uncertainty in three input parameters using different non-intrusive approaches.
