This volume describes the use and internal details of a FORTRAN computer program that has been written for simulating the dynamic (transient) behavior of a dual-fired (coal or oil) ship propulsion system. The FORTRAN program implements and solves a system of coupled, nonlinear, first-order, ordinary differential equations that represent all major components of the ship propulsion system (feedwater pumps, boilers, headers, turbines, turbine/gears propeller shaft, and hull). These equations also represent all major control loops. The program incorporates a numerical linearization subroutine that can be used to generate the steady-state conditions for any operating point. This subroutine also produces a linearized version of the model that describes the transient behavior of the propulsion system in a neighborhood of the steady-state operating point. The eigenvalues (reciprocal time constants) of this linear model are also generated. A copy of the FORTRAN program is available on magnetic tape from MARAD.
