Hydrodynamic Equilibrium Conditions for AG(EH) Main Strut-Pod-Foil System Using Flap Incidence Control,
Abstract
The power requirements for hydrofoil craft control systems has been a subject of recent concern as the U.S. Navy considers larger and larger craft. Four hydrofoil configurations were investigated theoretically to determine power requirements to control a hydrofoil ship similar to the AG(EH) in a random sea, and a pivoted foil with leading-edge tab was found to consume the least power. To determine whether this configuration would actually consume the least power, a 1/12-scale model was examined for equilibrium flap/foil angle conditions ('stable flying situations') of the fully-wetted case. A passive control system comprised of mechanical linkages was used with the model to obtain steady-flow, fully-wetted conditions. The results of this experiment are discussed.
