In combination with the hydro-piezoelectric drive

bionics and water-jet thrust technology

a novel piezoelectric water-jet thrust was introduced

and the core of the thrust—piezoelectric jet pump was studied. The design

principal

process and performance of the pump jet were presented

and a prototype pump was designed and manufactured in the laboratory. Through a series of experiments and tests

It is concluded that the piezoelectric pump jet is characterized by stable performance and bucky volume of liquid flow

the optimization frequency is 1250 Hz. With the sine wave signal actuated

the maximum liquid flow rate of the pump jet is 714 ml/min when driving voltage is 190 V.
