HULLBORNE HYDROFOIL SIX-DEGREE OF FREEDOM MOTION PREDICTION COMPUTER PROGRAM

A description of a motion prediction computer program for a hullborne hydrofoil is presented. This program computes the six-degree-of-freedom (6DOF) hydrofoil craft motions for a craft advancing at a constant forward speed, less than the critical "lift-off" speed, with arbitrary heading in regular waves. The structure of the program consists essentially of the already existing "DTNSRDC Ship-Motion and Sea-Load Computer Program" modified to incorporate the foil and strut system of a hydrofoil craft. Presented in this report is a brief discussion of the mathematical model, input information pertaining to the hydrofoil and a discussion of the results. The Appendicies present a listing of the foil coefficients, data card format description for the original program, and a program listing. (Author)
