ABSTRACT

Sensitivity analysis is a methodical procedure for assessing how changes to the input variables influence the output or result of a model, system, or decision. It measures how sensitive or responsive the outputs are to changes in the inputs. Sensitivity analysis offers a thorough knowledge of the dynamics inside a system by evaluating the effects of various hypotheses and scenarios. The aerospace industry continuously works on a number of variables and constants, which influence the output in the system. It is essential to quantify the effect of the input parameters on the output parameters to get an insight into the system. Sensitivity analysis can be utilized to quantify the influence of the input on the output parameters. In this chapter, the procedure to conduct the sensitivity analysis and the necessary steps are explained with an example of a multielement airfoil. The sensitivity indices of the position of the flap and slat were computed to quantify the effect on the aerodynamic coefficients. A well-validated computational solver is used for this study and the results show the effect of each input on the output parameter.
