Longitudinal distribution of hydrodynamic load on a gliding flat-bottomed plate with keel
Abstract
Experiments were conducted in a water tunnel to determine hydrodynamic load distribution on a flat-bottomed plate with keel gliding on the water surface without wetting its chines. The transverse roll angle of the plate was 30 deg. The results are interpreted in light of a wing analogy which ascribes to the cross section of the gliding plate half the lift force of a flat delta wing, with correction for roll. Wing-analogy calculations agree well with experimental results.
