Synopsis

Excerpt from Wind-Tunnel Investigation of Control-Surface Characteristics, Vol. 19: A Double Flap With an Overhang and an Internal Aerodynamic Balance

The tests were made in the Naca y 6~foot vertical tunnel (reference 2) modified as discussed in reference 5. The 2-foot-chord by h-foot-span model was made of lami hated mahogany, except for the front flap which was steel. The airfoil conformed to the naca 66-009 airfoil contour forward of the forward-flap hinge axis and to a straight line contour behind this hinge axis. The model was pro vided with a forward flap and a 0.2oc rearward flap. Figure 1 shows the me.hod used to connect the flaps to each other and to the airfoil. He rearward flan was connected to the forward flap by a mechanism that allowed he rearward flap to deflect one, two, or three times as fast as the forward flan; that is, doz/ddl equals either 1, 2, or 5. Mhe forward flap was orovided with three interchangeable blunt-nose overhang balances and three interchangeable internal balances having chords 25, to, and 50 percent of the forward-flan chord. The arrangements tested and pertinent model dimensions are shown in figure 2.
