Abstract : The digital computer simulation of the six degrees of freedom equations of motion for the XR-3 captive air bubble testcraft is presented. The origin of this computer program is the SES Loads and Motion Program developed by Oceanics Inc. for the Bell 100 ton (100B) surface effect ship. Modifications and procedures used in the revision of the subroutines to convert the L and M Program from the 100B model to the XR-3 model is documented. Measurement data from XR-3 test runs are used to verify the model for steady-state operating conditions in calm water. Computer output for turn maneuvers in calm waters and for regular sea conditions are included. (Author)
