Abstract

580,806. Turbine and like blades. GRIFFITH, A. A. May 21, 1941, No. 6533. Drawings to Specification. [Class 110 (iii)] The blades of a turbine, compressor or the like have a surface sufficiently rough to disturb the boundary layer of gas flowing over it. The blades may be undressed sand-castings of a high nickel-chrome steel, or, 80:20 nickelchromium alloy. Specification 585,330 is referred to.
