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.
