Department of the Navy. Bureau of Aeronautics. contributor: Langley Aeronautical Laboratory date: 1947-09-25 language: English description: A 1/5.5-size powered dynamic model of the Columbia XJL-1 amphibian was landed in Langley tank no. 1 in smooth water and in oncoming waves of heights from 2.1 feet to 6.4 feet (full-size) and lengths from 50 feet to 264 feet (full-size). The motions and the vertical accelerations of the model were continuously recorded. The greatest vertical acceleration measured during the smooth-water landings was 3.1g. subject: Columbia XJL-1 subject: hydrodynamics rights: Public rights: Public Domain rights: No Copyright, Unclassified, Unlimited, Publicly available type: Report format: [22] p. : ill. format: Text identifier: url: http://hdl.handle.net/2060/20050019362 identifier: rep-no: NACA-RM-L7H29 identifier: casi: 20050019362 identifier: https://digital.library.unt.edu/ark:/67531/metadc64233/ identifier: ark: ark:/67531/metadc64233
