Abstract: Intake swirl is an essential disturbing parameter related to the compatibility between intake and engine. Anti-Swirl protection measures are researched for existent airplanes proceeding form airplane configration and engine design. It is discovered now that top-bent stator blades in front stage of low-pressure compressor are valuable to enhance the anti-swirl ability of engine and to reduce the sensibility to swirl disturbance, which would be applied in aeronautical engineering.
