Fluerics 41: Single-Sided Control Port Characteristics of Laminar Proportional Amplifiers for Arbitrary Input Loading

Abstract

This report presents a technique for analytically predicting single- sided control port characteristics of a laminar proportional amplifier (LPA) with arbitrary input circuits at the opposite control using calculable differential characteristics. Specific cases dealt with include a constant pressure at the opposite control, a constant flow at the opposite control, and a series and shunt flow resistance at the opposite control. Experiments using amplifiers at various aspect ratios (height-to-width ratio of supply nozzle) and supply pressures, which imply a large range of LPA resistance, show a maximum error of 11 percent between actual and computed single-sided control port flow resistance.
