Keywords: propulsion/airframe integration, supersonic air-inlet, cfd, wind tunnel test

The performance of a boundary-layer diverter for supersonic propulsion system was evaluated mutually in terms of propulsion system and airframe by using CFD. Additionally, the ramp configuration which prevents the boundary-layer ingestion into the inlet was examined. Wind tunnel tests were also conducted to validate those results.
