Abstract:
Model tests were made at various displacements, center of gravity locations, and foil angles to evaluate two hull-foil combinations. The forward foils were surface-piercing dihedral foils, and the two alternative aft foils were a horizontal submerged foil with two struts and a dihedral submerged foil with a single strut. The struts and foils were of ogive sections. The singlestrut aft foil gave the least drag in the takeoff range but the double-strut foil was better in the flying range. It was evident that the forward foil controlled the flying height whereas the aft foil controlled the flying trim. Author
