Scher and Irene G. Young.NASA TN D-6423Washington, D.C. :National Aeronautics and Space Administration ;Springfield, VA :For sale by the Clearinghouse for Federal Scientific and Technical Information,1971.10 p. :ill. ;28 cm.NASA technical note ;D-6423Prepared at Langley Research Center."September 1971."--Cover.N 71-33395.Includes bibliographical references (p. 10).Free-body tests were made in the Langley spin tunnel to determine drag coefficients for 1.07-meter-diameter (3.5-foot) flat circular parachutes when restrained by wire frames in a series of shapes representing those that parachutes assume during the inflation process. Both high-porosity (stable) and low-porosity (unstable) parachutes were investigated. The results obtained should be applicable to inflation analyses for flat circular parachutes.Mode of access: Internet.Drag (Aerodynamics)Parachutes.Young, Irene G.United States.National Aeronautics and Space Administration.Langley Research Center.01144726820101110143407.020141009010000.020141112165512.02025-01-01T19:23:24Z2025-01-01T18:30:02ZSDR-UIUCUNKNOWNloader.pl-003-020BKsdr-uiuc6403830uiugSDRUIUCuiug.30112106640268UIU6403830UIUUIUC20250101googleuiug.301121066402681971pdbibUS fed doc
