Research of Micro Airstream Gyroscope Sensitive Mechanism

Abstract:

The sensitive mechanism of micro airstream gyroscope was explained by calculating the distributing of stream field in the sense organ. According to the real size of micro airstream gyro-scope, ANSYS-FLOTRAN CFD was used to create models and work out the gas flow field and distributing in the two-dimensional chamber with different angular velocities. The results show that while the gyroscope in a static state the gas velocities at both hot-wires are equal as well as the current, and the output voltage is zero. On inputting an angular rate the gas velocities differ and a voltage signal proportional to the input angular rate is achieved.
