An Experimental Study of a Series of Flapped Rudders.
Abstract
Water tunnel experiments were performed to determine the freestream characteristics of a series of twelve rudders with systematic variations in the amount of flap area and flap balance. The results include plots of lift, drag, rudder moment and flap moment coefficients for a complete range of angles of attack and flap deflections. A comparison is made of the effectiveness of all-movable rudders, rudders with a fixed skeg and movable flap, and rudders with movable skegs and flaps. Maximum flap moments with zero balance are compared to the maximum moment of a balanced all-movable rudder.
