This thesis addresses the aerodynamic shape optimization of a missile engine inlet cover, a component designed to prevent windmilling on the gas turbine engines during the gliding phase of the missiles. The adjoint-based optimization is conducted with the open-source SU2 software suite. The cover shape is controlled by means of a Free Form Deformation box control points. The design objectives are to minimize the drag and maximize the opening moment of the inlet cover at the same time. Both single and multi-objective optimizations with weight factors are performed. The findings are discussed in detail, and it is shown that the optimization process provides new cover shapes for increased aerodynamic performance compared to the quarter-spherical baseline cover.
