NACA-ARR-L4I11 REV F
Wind-Tunnel Investigation of Control-Surface Characteristics XX - Plain and Balanced Flaps on an NACA 0009 Rectangular Semispan Tail Surface
Year: 1944
Abstract: Correlation is established between aerodynamic characteristics of control surfaces in two-dimensional and three-dimensional flow. Slope of lift curve was affected little by overhang and balance-nose shape, but increased by sealing flap-nose gap. Effectiveness of balancing tab was same for sealed plain flap and unsealed overhang flap. Changes in hinge-moment coefficient were diminished by sealing gap. Values measured by three-dimensional flow disagreed with two-dimensional flow values until aspect ratio corrections were made.
