Full Design

An analysis has been conducted on the flapper-nozzle stage of a two-stage electrohydraulic controller that has been specifically designed to be a stable, stand-alone dynamic system. Calculations performed on equilibrium control pressures, stage gain, and frequency response characteristics agree with values obtained experimentally to within close limits. The analysis applies generally to a flapper-nozzle combination using any set of dimensions convenient for the designer. Flow-pressure equations and flapper dynamic properties have also been given to enable the designer to obtain full design characteristics.
