APPLIEATION OF LEANED BLADES TO AN AEROENGINE

In order to match the low pressure compressor with the high pressure one,the outlet guide vane blades of the low preseure compressor have been designeed to be leaned circumferentially and radially.The two types of the leaned blades have been tested in an aeroengine.The results show that the leaned blades obviously improve the compressor performance in the hub region,decrease the radial pressure ratio gradient and control the flow at the end wall.
