Abstract

750,305. Boundary layer control. ROLLSROYCE, Ltd. Feb. 5, 1954 [Feb. 5, 1953], No. 3339/53. Class 4. A blade 10 for an axial flow turbine or compressor is provided on one or both surfaces with a spanwise-extending continuous or intermittent recess 15 located chordally at a point or points upstream of the position at which the boundary layer would otherwise break away. The presence of the recess converts the laminar flow into tubulent flow to delay the breakaway.
