Hinge moment reduction for the AG(EH) main strut-pod-foil assembly by use of trailing edge tabs

Hydrodynamic loading on a 1/12th scale model of the ag eh main strut-podfoil was experimentally examined at various velocities, depth of hydrofoil submergence, strut-pod pitch angles, and foil angles of attack. The results, which are in agreement with previous experiments, show that the lift center of p taper ratio 0.3, and leading edge sweep angle 0.724 rad or 41.5 deg is located at 70 to 90 percent of the mean geometric chord. Thus, the experimental results could not be compared directly to the empirical two-dimensional theory that was developed since it had been assumed that this lift acted at mischord.
