A Multi-functional Micro-machined Gyroscope for Rotating Aircraft
In this paper,we present recent work on the design,fabrication,and packaging of a new gyroscope,by silicon micromachining,for the autopilot of rotating aircraft.The multi-functional micro-machined gyroscope generates the gyroscope effect driven by the roll of rotating carrier,and sense the roll frequency in the longitudinal axis direction of rotating carrier and the transverse angular rate in the perpendicular direction of longitudinal axis of rotating carder.In addition,the transverse angular rate can be decomposed into the yaw angular rate and pitch angular rate with the geographic coordinates of reference.Therefore,multi-functional micro-machined gyroscope can sense angular rate in three directions,and the signal of gyroscope can be calculated into the five parameters,including the transverse angular rate,azhnuth angle,yaw angular rate,pitch angular rate and roll frequency.The new gyroscope has the functions of three the general rate gyroscopes mounted vertically and fits for the attitude control of rotating aircraft.
