title: Spin-Tunnel Investigation of a 1/28-Scale Model of a Subsonic Attack Airplane creator: Lee, Henry A. creator: Healy, Frederick M. contributor: Langley Research Center date: 1964-07 language: English description: "An investigation has been made of a 1/28-scale model of the Grumman A-6A airplane in the Langley spin tunnel. The erect spin and recovery characteristics of the model were determined for the flight design gross weight loading and for a loading with full internal fuel and empty external wing fuel tanks. The effects of extending slats and deflecting flaps were investigated" (p. 1). subject: aircraft communications subject: navigation subject: scale models subject: Grumman A-6A rights: Public rights: Public Domain rights: No Copyright, Unclassified, Unlimited, Publicly available type: Report format: 22 p. : ill. format: Text identifier: local-cont-no: 94X71135 identifier: url: http://hdl.handle.net/2060/19940040848 identifier: rep-no: NASA-TM-SX-964 identifier: rep-no: NACA-AD-3156 identifier: casi: 19940040848 identifier: https://digital.library.unt.edu/ark:/67531/metadc63698/ identifier: ark: ark:/67531/metadc63698
