REAL-TIME SIMULATION OF A STEAM PROPULSION PLANT

A ship propulsion training device has been developed which combines full-scale physical replication with math modeling and digital computer simulation. This trainer, Device 19E22, 1200 PSI Propulsion Plant Trainer, is now operating at the Surface Warfare Officers School, Newport, Rhode Island. The development of this large trainer resulted in several first-time achievements: An integral math model of a complete ship's steam propulsion plant and auxiliaries with real-time digital computation; electronically generated and computer controlled machinery sounds including normal and casualty operating conditions; and full-scale mockups of fire room, engine room, auxiliary spaces and electrical central with functioning man-machine interface instrumentation and controls. With these features this trainer is able to simulate plant conditions where casualty training can be provided to a degree never before available in the Navy's surface propulsion plant training. Generic math models were developed for pumps, turbines, heat exchangers, etc., and design data for each component was then incorporated with the generic model to develop specific models. The automatic combustion control system was modeled as well as the ship's electrical generators and power distribution system. Programming of the math models required approximately 50,000 instruction. The basic iteration rate is two per second by a 24-bit machine with 64K words of core memory and 750K words of disc memory. In addition to providing a new dimension in training, this device has potential as an engineering tool to evaluate changes in plant components and operating procedures.
