Prust, Jr., and Ronald M. Helon.Washington, D.C. :National Aeronautics and Space Administration :[For sale by the Office of Technical Services, Dept. of Commerce],[1972]21 p.:ill. ;26 cm.NASA technical note ;NASA TN D-6637"January 1972."--Cover.Major NASA subject terms: Fluid Dynamics, Stator Blades, Trailing Edges, Turbine Blades, Cascade Wind Tunnels, Kinetic Energy, Pressure Measurement, Static Pressure, Strain Gages.Includes bibliographical references (p. 11).The experimental and analytical investigation included solid blades with five different trailing-edge thicknesses and four different trailing-edge geometries. One of the geometries was round, one was square, one was tapered from the suction surface, and the other tapered from the pressure surface. One of the trailing-edge thicknesses was sharp edged; the other four thicknesses were equivalent to about 5, 11, 16, and 20 percent of the blade throat width. The experimental results show increased efficiency loss for increased trailing-edge thickness for all trailing-edge geometries. The blade with round trailing edge, equal to about 11 percent of the blade throat width, had 60 percent more loss than the sharp-edged blade. For the same trailing-edge thickness, square trailing edges caused more loss than round trailing edges, and the tapered trailing edges caused about the same loss as the round trailing edges.Mode of access: Internet.Wind tunnels.PressureMeasurement.Fluid dynamics.Geometry.Lewis Research Center.United States.National Aeronautics and Space Administration.01144505520101110150704.020141009010000.020141112165512.02025-01-02T19:12:34Z2025-01-02T18:30:02ZSDR-UIUCUNKNOWNloader.pl-003-020BKsdr-uiuc6403979uiugSDRUIUCuiug.30112106883173UIU6403979UIUUIUC20250102googleuiug.301121068831731972pdbibUS fed doc
