Development of Fluidic Logic Start-Up System for Main Forced Draft Blowers

摘要

A pure fluid automatic start-up system for main forced draft blowers was designed. A breadboard system was developed and evaluated to determine performance characteristics and suitability for naval use in the automatic start-up of auxiliary turbine driven machinery. The breadboard system was constructed from fluidic logic devices. Tests to evaluate the system were conducted with the aid of an analog computer simulation of a main forced draft blower and associated equipment. The results of these tests indicated that a digital logic system constructed of bi-stable fluidic devices could perform satisfactorily the operations required in lighting-off a forced draft blower and bringing it to a condition suitable for transfer to control by an analog control system.
