Institut für Flugsystemtechnik, through the American Institute of Aeronautics and Astronautics Aerodynamic Deceleration Systems Technical Committee.Includes bibliographical references.A free-flight investigation of a redio-controlled model of a manned reentry spacecraft with a telescoping rigid parawing as a recovery system was made to evaluate the deployment process and the stability and control characteristics of the configuration. Flight tests showed that the parawing could be deployed from a packaged condition, but that the deployment process must be a sequence of carefully controlled and timed events, and that some portions of the deployment should not occur at too fast a rate. The most significant single factor learned about the deployment process was that the parawing had to be slowly rotated to a lifting condition. Transition which is too fast from zero lift to maximum lift would result in a tumbling motion. After the parawing was deployed, the configuration was stable and controllable.Mode of access: Internet.ParachutesModelsDeploymentTesting.Space vehiclesModelsAtmospheric entryTesting.Langley Research Center.United States.National Aeronautics and Space Administration.01143274720101101074609.020141013010000.020141112173021.02026-01-21T19:19:18Z2026-01-21T18:30:03ZSDR-UIUCUNKNOWNloader.pl-003-020BKsdr-uiuc6389439uiugSDRUIUCuiug.30112106864462UIU6389439UIUUIUC20260121googleuiug.301121068644621963pdbibUS fed doc
