Left Panel: Isometric rendering of the best performing geometry from the primary fairing shape family. The fairing is defined by the following design variable values: x1A = 122 cm, \(\overline{x_{2A}}=0.0\), and x3A = 183 cm. Right Panel: Isometric rendering of the best performing secondary fairing shape. The fairing is defined by the following design variables: x1A = 74 cm, \(\overline{x_{2A}}=0.0\), x3A = 191 cm, and x1B = 30 cm
