COMPUTER-AIDED SHAPE DESIGN OF AN UNDERWATER HULL

The paper describes a computer-aided design method for creating the 3D model of an underwater hull based on the use of B- spline curves. With the constructed program, a three dimensional underwater hull can be designed by setting the cross sections at different positions from forebody to tail. The configuration of the hull can be modified by changing the following parameters: 1) geometry shape of cross sections; 2) distance between two cross sections; 3) inserting a new section between two different cross sections; and 40 tangent vector or radius of curvature at hull nose. In addition, a computer program for generating a 2D grid mesh of the flow environment around the underwater hull is also constructed to prepare for the CFD work.
