Measurements of the free water surface displacements caused by a hydrofoil of moderate aspect ratio (A Supplement to Motion Picture No. 62)

Brentjes, J.

Abstract

The purpose of this experimental study is to determine the contour of the distorted water surface behind a hydrofoil operating at shallow depths of submergence. The effects of foil depth, Froude Number, and the angle of attack were investigated for a non-cavitating hydrofoil without any flap deflections. The characteristics of the surface depression behind a foil are important when considering the applications of canard or tandem foil systems. A theoretical analysis of the same phenomena is being made by Daniel Ai and a comparison between theory and experiment will be made in the near future.
