Recent advances in steady compressible aerodynamic sensitivity analysis

An overview is given of some recent accomplishments by different researchers in calculating gradient information of interest from modern flow-analysis codes. Of particular interest here is advanced computational fluid dynamics (CFD) software, which solves the nonlinear multidimensional Euler and/or Navier-Stokes equations. The accurate, efficient calculation of aerodynamic sensitivity derivatives is very important in design-oriented applications of these CFD codes to single discipline and multidisciplinary problems [1, 2].
