This presentation will describe recent research in aerodynamic shape optimization based on the numerical solution of the Euler and Reynolds-averaged Navier-Stokes equations. The basic methodology includes a parallel implicit flow solver based on SBP-SAT finite-difference schemes on multi-block structured grids combined with a discrete adjoint approach to gradient computation along with B-spline based geometry parameterization and an efficient integrated approach to mesh movement. Topics covered will include the flow solution algorithm, geometry parameterization and mesh movement, the adjoint method, gradient-based optimization algorithms for multi-modal problems, and application to the design of unconventional aircraft.
