PREDICTION OF THREE-DIMENSIONAL PRESSURE DISTRIBUTIONS ON V-SHAPED PRISMATIC WEDGES DURING IMPACT OR PLANING

A computer program has been developed which calculates the water-pressure distribution on V-bottom prismatic wedges during impact or planing. The method of computation is based on previously published semiempirical procedures with several modifications that facilitate programing and result in close correlation to recently published experimental data. The prismatic wedge may have any positive value of trim, deadrise angle, and wetted length. The pressure distribution for the entire hull or any given section of the hull may be calculated in specified increments by using the appropriate input data. Results obtained from the program are in reasonable agreement with certain published experimental planing data.
