The goal of the study was to determine the optimum sets of equations to be used with two general types of submarine trainers. The equations of motion used were those developed by the Naval Ship Research and Development Center. They were reduced into two sets for use in training simulators, one for a basic submerged control maneuvering trainer and one for an advanced submerged control simulator to provide highly realistic ship control training through the full range of normal and casualty conditions. The report outlines a general-purpose digital computer program, following the NSRDC standard equations written in FORTRAN. Integration methods for digital simulators are discussed. A number of programs for testing the degree of simulation of a digital simulator program are given. Use of these programs as applied to submarine simulation is shown with two sets of equations which eliminate 73 of the 139 coefficients used in the original NSRDC equations. The mathematical model for a submarine simulator using a very small computer is developed. A discussion of near-surface operation and wave-generation is followed by the general requirements for determination of the simulation requirements for training as opposed to research.
