Abstract:

Results of experimental research in newly conceived high gain fluid state proportional amplification techniques are presented. In particular the Double Leg Elbow Amplifier DLEA concept was partially optimized, then tested under varying conditions typical of system requirements. This included experimental studies of steady state performance plus the effects of dynamic and transient inputs, output loading, variable input flows, and differing element sizes. The results demonstrated that the Double Leg Elbow Amplifier can provide a linear, repeatable differential mass flow gain of over 2201 and that it is not seriously affected by large changes in supply flow level or element size or by moderate changes in the output loading. Tests were also conducted to study the possible advantages of amplification obtainable by injecting a control flow at the throat of a converging-diverging nozzle called Aerodynamic Throat Modulation.
