ABSTRACT:
An angular rate sensor is provided having a specially shaped nozzle which shapes the velocity profile of a gas stream passing through a nozzle so that a linear portion of the profile impinges upon the resistive elements of the sensor even when large angular rates of turn in a plane of sensitivity are encountered. The nozzle is generally rectangularly shaped having a pair of parallel sides arranged perpendicularly to the resistive elements of the sensor and a pair of connecting sides.
