The potential benefits of short, highly compact inlet systems extend from efficient propulsion/airframe performance to improved survivability. The cost of these benefits, however, may be excessively high engine face distortion. This highlights the importance of accurate preliminary design methods that assure low distortion engine face flow. Therefore, we have investigated compact/offset subsonic diffuser performance and operational characteristics with the general goal of developing preliminary design guidelines and providing a useful perspective for advanced aircraft designers. This work incorporates important prior work and extends the data base by introducing the results of recent experiments. The paper discusses passive and active BLC methods for providing separation-free diffuser flow and compares CFD methods with the experimental results to validate the applicability of the methods and highlight aspects of the diffuser flow phenomena.
