Flapped Hydrofoil Tests. Water Tunnel Tests of the NACA 64A-309 Foil Section Fitted with an Adjustable Flap in Fully-Wetted and Cavitating Flows.

Abstract

Lift, drag and pitching moment data for a NACA 64A-309 foil section fitted with a plain sealed flap are presented. The flap hinge axis was located at the three-quarter chord point. The influence of positive and negative flap angles on the data was evaluated in fully wetted and cavitating flows. The data were taken in the two-dimensional working section of the GALCIT High Speed Water Tunnel. (Author)
