Abstract

As part of future civil aircraft concepts the integration of jet engines is considered as an additional possibility to increase the efficiency of the whole aircraft. While the ingestion of the fuselage boundary layer reduces the drag of the aircraft it also causes the fan stage of the engine to operate with a distorted inflow. In this study, a fan with a low total pressure ratio, representing future fan designs, and the fan of the International Aero Engines (IAE) V2500 engine, representing a common fan design in today’s jet engines, are imprinted with a parameterized generic but also realistic inlet distortion. The numerical investigation of both fans that employed transient full-annulus simulations showed that regarding different criteria the low pressure ratio fan is more sensitive to the imprinted inlet distortion.
