Application of Fluidic Concepts to Hydraulic Control Systems

Abstract

A survey is presented of the experimental work that has been done in the area of hydraulic fluidics. The importance of Reynolds number is shown when comparing the performance of a fluidic element with hydraulic oil or air as the working fluid. The results of testing of all-hydraulic fluidic actuator control systems conducted at General Electric Company and at the Naval Ship Research and Development Center support the premise the hydraulic fluidic elements are useful in improving all-hydraulic servo-actuator controls. A small scale test conducted at NCEL with pneumatic fluidic elements showed that a pneumatic actuator can be powered directly by a fluidic amplifier cascade at the lower power levels.
