ABSTRACT:
A three-axis navigational guidance system utilizes three specially designed internal jet-type fluidic angular rate sensors which simultaneously sense the rotational rate of a guided body relative to three mutually perpendicular control axes. Fluidic output signals from the sensors are converted to electrical signals which are used to maintain the body in a preselected attitude relative to each of the three axes. The sensors are rendered extremely accurate by means of unique calibration mechanisms associated therewith which compensate for or correct for fabricational inaccuracies in the sensors. The operation of the rate sensing portion of the guidance system is environmentally stabilized by a novel jet-control system which automatically maintains the Reynolds number of each sensor jet within a predetermined range to thereby substantially eliminate jet drift.
