Report of tests of a compressor configuration of DCA blading.

Abstract

Results of an experimental program to measure the performance of a compressor stator cascade consisting of 20 DCA blades of chord 5.01 inches, aspect ratio 2.0 and solidity 1.67 under conditions of varying incidence angle and Reynolds number are reported. Flow quality and blade performance data were obtained using pneumatic probe surveys and surface pressure measurements. Changes in Reynolds number in the range of 500,000 to 770,000 did not measurably effect either flow quality or blade performance. Changes in incidence angle over the range -15 to 10 degrees produced generally well behaved blade performance parameters.
