Effect of Wedges on the Performance Characteristics of Two Planing Hulls

A. Millward

Open publisher page 17 citations

Abstract

An investigation has been made into the effect of adding wedges or trim tabs to two models of the DTMB Series 62 planing hulls over a range of longitudinal center of gravity positions and displacements to determine the optimum wedge configuration and the range of effectiveness of a wedge. Measurements were also made to confirm that a wedge has an effect on the dynamic lift on the hull and hence that there is a change in resistance other than that resulting from control of the trim angle.
