Book Description
The principal characteristics of an surface having an angle of dead rise of 40 degrees and horizontal chine flare are presented. The data indicated that at a given trim the important planing characteristics depend mainly on lift coefficient. The effects of increasing the basic angle of dead rise from 20 degrees (NACA TN 2804) to 40 degrees are to decrease the ratio of the center-to-pressure location to the mean wetted length, to decrease the extent of pile-up of water at the keel, and to increase the friction drag.
