Jet rotor gyro based on expansion-contraction tube micropump

The utility model relates to a jet rotor gyro based on an expansion-contraction tube micropump and belongs to the field of inertia measurement. According to the utility model, a detection cavity of the jet rotor gyro is respectively communicated with corresponding vibration cavities through corresponding air outlets; the air outlets are staggered in a radial direction; the air outlets are conical channels; the small ends of the air outlets are connected with the detection cavity while the big ends of the air outlets are connected with the vibration cavities; meanwhile the vibration cavities are communicated with the outside through conical air inlets; and the small ends of the air inlets are connected with the outside while the big ends of the air inlets are connected with the vibration cavities. According to the utility model, the characteristics of synthetic jet are fully utilized and the difference of the resistance of the air inlets and the air outlets to airflow is utilized to ensure that the directional
