Abstract
1,051,406. Boundary layer control. Z. MORAVEC. June 25, 1964 [July 2, 1963]. No. 26296/64. Heading F2R. [Also in Division F1] To reduce siren noise in axial flow bladed machines such as compressors and turbines, auxiliary air or liquid is supplied to the interior 7, Fig. 2 (not shown), of the stator or rotor blades 6 to issue through a slot 9 in each blade trailing edge as a stream 8 and accelerate the wake 10 behind the blade, caused by boundary layer effects, to substantially the speed of the working medium outside the wake.
