The objective of this concurrent computational and experimental study is the design optimization of a submerged inlet. The experimental study was performed to validate the accompanying computations and to provide additional information regarding the Pareto Set of optimal designs. A stainless steel model with a removable submerged inlet was installed in the Rutgers University Low Speed Wind Tunnel. Using input from the accompanying computational study, the submerged inlet was successfully designed and fabricated using the Rutgers University Rapid Prototyping System. The experimental setup and necessary instrumentation for all experiments were successfully built. All the data obtained using a pressure differential technique were collected using a rotating in-house built Pitot rake connected with pressure acquisition system. A turbulence study and verification of the experimental findings obtained using a Pitot rake was performed using the Rutgers University thermal anemometry system. Experimental evaluation of the baseline inlet and optimum inlet for zero angle of attack and yaw showed a consistent trend between experimental and computational results in reduction of the Distortion Coefficient (DC). Also, the Distortion Coefficient improved for the optimum inlet compared to the baseline inlet for negative angles of attack and all yaw angles.
