NACA-ARR-L5F06
Wind-tunnel investigation of control-surface characteristics XXII - medium and large aerodynamic balances of two nose shapes and a plain overhang used with a 0.20-airfoil-chord flap on an NACA 0009 airfoil
Year: 1945
Abstract: Blunt-nose and elliptical-nose overhangs of 0.35 and 0.50 flap chord and a plain overhang on a flap having a chord of 0.20 airfoil chord have been tested in two-dimensional flow on an NACA 0009 airfoil. The results of the tests are p resented as aerodynamic section characteristics for several flap deflections with the gape at the flap nose sealed or unsealed. Tests were made also to determine the effectiveness of a tab of 0.20 flap chord on the plain sealed flap and on a sealed flap having an elliptical overhang of 0.35 flap chord. The pressure difference across the flap seal was also determined for the plain sealed flap.
