Performance and application of the vortex rate sensor
Abstract
The vortex rate sensor is a pure fluidic device with no moving parts that senses angular velocity about its input axis and provides a signal proportional to that velocity. The three basic parts of the sensor are the coupling element, the vortex chamber, and the signal pickoff. Attention is gven to sensitivity, accuracy, and response time and to sensor design and fabrication with emphasis on housing and manifold, null adjust and built-in test and temperature compensation. A number of applications of the vortex rate sensor are considered: aircraft flight controls, ejection seat stabilization, and helicopter gun turret stabilization.
