Abstract

730,147. Reducing surface friction. MASCHINENFABRIK OERLIKON. July 30, 1953 [Aug. 28, 1952], No. 21211/53. Class 4. In a hollow blade for a compressor or the like, the surrounding fluid is drawn into the interior of the blade by the provision of apertures 6 and/or 7 in the wall of the blade and an aperture 8 in the trailing edge whereby a flow is induced through the blade from the apertures 6 and/or 7 to the aperture 8 to prevent breakaway of the streamlines over the rear portion of the blade.
