An Experimental and Theoretical Study of Planing Surfaces with Trim Flaps

摘要

Experiments were made on a 10 deg deadrise prismatic planing surface over a range of speed both with and without full span and half span trim flaps fitted at the transom. The lift, drag and pitching moment characteristics are summarized in planing formulae which account for the effect of transom flaps and include the flap hinge moments. (Author)
