Fluerics 42: Some Commonly Used Laminar Fluidic Gain Blocks

This report presents data and operating experience information on many commonly used laminar gain blocks from two to eight stages. In addition, as an aid to design, a short computer program is presented, suitable for use with a pocket programmable calculator. Outputs from this program and flows and staged gain. Also available is the net gain and the bandwidth at 90 deg of phase shift. Several examples of this program are given to cover multiple-stage gain blocks. As an example of the utility of the program, a step-by-step tradeoff study is presented for the Massachusetts Institute of Technology fluidic servovalve, for which an attempt is made to maximize bandwidth and minimize leakage flow.
