THRUST DEDUCTION DUE TO A PROPELLER BEHIND A HYDROFOIL

Abstract

A method which is based on Lagall's heorem is presented for computing the resistance augmentation, or thrust deduction, for submerged hydrofoil-propeller arrangements. The effect on the magnitude of thrust deduction of foil lift, propeller load, foil span, foil flap angle, and propeller-foil spacing was investigated. Computed examples and experimental thrust-deduction results for several hypothetical arrangements showed good agreement.
