Abstract

812,273. Boundary layer control. HAUSAMMANN, W. May 10, 1955 [May 10, 1954], No. 13555/55. Class 4. [Also in Group XXVI] A turbine or compressor comprising at least one duct formed between the hub surface and partition walls 152 of the rotor and an outer surface, and a sill 155 on the hub or outer surface which faces upstream in the case of a compressor and downstream in the case of a turbine and is arranged at an angle to the plane of the rotor, has the boundary layer removed from the sill by a suction pump 171 through the slot 156 and ducts 159, 161.
