Report of Tests of a Compressor Configuration of CD (Controlled Diffusion) Blading.

Abstract

Results of 14 tests in a subsonic cascade are reported in which the air inlet angle and Reynolds number were varied. The cascade contained 20 Controlled Diffusion (CD) blades, with 5.01 inches chord, aspect ratio of 2.0 and solidity of 1.67. Pneumatic probe surveys and surface pressure measurements were used to obtain blade performance and flow quality data. There was no measurable influence of the Reynolds number on the blade losses in the range of Re. = 474000 to Re. = 690000. Fourteen tests, using seven different inlet air angles over a range of 24 to 46 degrees generated generally well behaved blade performance parameters. The results were compared with previous results from a Corresponding cascade of DCA blades. (Author)
