Description

Report presenting shadowgraphs of flow patterns through the blade passage and ahead of a compressor rotor by shining parallel light rays approximately radially onto a rotor hub and upstream inner ring, which was painted white to serve as a screen. The flow patterns were used in conjunction with measured data to analyze the performance of two axial-flow supersonic compressors over a range of Mach numbers in Freon-12. The shadowgraph was found to be a useful tool for comparing the flow patterns within rotors and cascade sections and improving compressor analysis.

National Advisory Committee for Aeronautics Collection

The National Advisory Committee for Aeronautics (NACA) was a U.S. federal agency founded on March 3, 1915 to undertake, promote, and institutionalize aeronautical research. On October 1, 1958 the agency was dissolved, and its assets and personnel transferred to the newly created National Aeronautics and Space Administration (NASA).
