A Method for Synthesis and Selection of Propulsion Plants for Submarines

New concepts for submarine propulsion plants are continuously being presented to the Navy for review and possible application. An analytical method is now being used to determine the effect of powerplant weight and thermal efficiency on the cruising radius, speed, and vessel displacement. A mathematical model representing the propulsion plant and vessel hull was prepared and, by means of a digital computer, the effects of varying several design parameters were studied. By comparing the predicted performance of several types of powerplants with the results of the computer study, it is possible to select those which justify further development for Navy use.
