Steinke.Washington, D.C. :National Aeronautics and Space Administration ;Springfield, Va. :For sale by the National Technical Information Service [distributor],1976.94 p. :ill. ;27 cm.NASA technical memorandum ;X-3341"NASA TM X-3341."Performing organization report no.: E-7604."February 1976."Cover title.Includes bibliographical references (p. 20).The overall and blade-element performance of a low pressure ratio, low tip speed fan stage is presented over the stable operating range at rotative speeds from 90 to 120 percent of design speed. Stage peak efficiency of 0.927 was obtained at a weight flow of 32.4 kg sec (190.31 kg sec sq m of annulus area) and a pressure ratio of 1.134. The stall margin at design speed and peak efficiency was 15.3 percent.Performed by Lewis Research Center, Cleveland, Ohio505-04Mode of access: Internet.AirplanesTurbofan engines.AirplanesTurbojet enginesCompressors.Axial flow compressors.CompressorsPerformance.Turbocompressors.nasatTables (Data).nasatFlow distribution.nasatEngine tests.nasatAerodynamics.nasatTip speed.nasatRotor blades.nasatEngine design.nasatSteinke, Ronald J.Lewis Research Center.01142597620101006140941.020141013010000.020141112173021.02025-01-01T19:14:53Z2025-01-01T18:30:02ZSDR-UIUCUNKNOWNloader.pl-003-020BKsdr-uiuc6363251uiugSDRUIUCuiug.30112105195967UIU6363251UIUUIUC20250101googleuiug.301121051959671976pdbibUS fed doc--NTIS: pubdate < 2020
