| Abstract: | The three-dimensional flow field of the twin flapper-nozzle servo-valve is analyzed by using FLUENT software, the controlled pressure and recovery flow rate in twin flapper-nozzle amplifier are obtained under different flapper-nozzle distance. The mathematical model of controlled pressure and recovery flow rate is established by function fit method. And the effect of twin flapper-nozzle＇s internal flow on the characteristic of servo-valve is analyzed. This study provides some reference to the design of twin flapper-nozzle servo valve to a certain extent. |
