Abstract

1,071,865. Boundary layer control. GENERAL MOTORS CORPORATION. Jan. 27, 1966 [Feb. 24, 1965], No. 3663/66. Heading F2R. An axial flow compressor, wherein the last three stages of compressor blading are shown at 17, 18, 19, discharges into an annular diffuser bounded by walls 2 and 25, the wall 25 diverging sharply from an inner shroud 33. The blading stages are bolted to the flange 21 of shaft 13 and a ring 29, also bolted to flange 21, forms an annular passage 38 within which are housed a ring of stator blades 39 attached to shroud 33 and a ring of rotor blades 41 attached to ring 29. Shroud 33 is spaced at 37 and 43 from blade row 19 and curved transition 30 of wall 25, respectively whereby, in operation, auxiliary compressor 41 draws air through passage 38 to deliver it over transition 30 and cause the boundary layer to adhere to wall 25. The apparatus may be used to cause the boundary layer to adhere to wall 2.
