Current methods take advantage of computational advances to compute the optimal design directly.
Application of the sensitivity equation method is studied in this work. This facility is used to test commercial and military jet engines under air flow conditions they would receive in flight. A nozzle to direct the flow, simulating flight at different angles of attack and yaw. The design of the forebody simulator is an important step in any test, since it shapes the flow profile to the engine inlet. In this study, we consider a two dimensional analogue of this problem.
