Lift and Drag for a Low Aspect-Ratio Surface Piercing Wing-Model in Deep andShallow Water

摘要

A model of a surface-piercing wing has been towed through the water at threespeeds in two opposite directions for different draughts (aspect ratio's) and angles of attack (drift angles) in both deep and shallow water to measure the longtitudinal and transverse forces on the wing-model. From these forces the lift-characteristics have been derived on basis of the angle of attack.
