A PRELIMINARY HYDROFOIL DESIGN INCORPORATING A CAVITATION FREE OPERATION REQUIREMENT,

Abstract

Four basic hydrofoil parameters were chosen as optimization parameters; (1) loading, (2) aspect ratio, (3) lift/drag ratio and, (4) the root bending stress. Consideration is given to only the static flying condition where all the load is carried by the total plan-form (i.e. there is no nacelle) and all the root bending stress is carried by foil thickness. A method for calculating the lift and drag characteristics of subcavitating hydrofoils operating near the free-surface is discussed.
