A rate gyro providing a fluidic output signal corresponding to the yaw rate of a vehicle, for use in an adaptive steering system. The gyro rotor is hydraulically supported and spun via tangential reaction jets connected in parallel with flapper nozzles situated to provide both a differential pressure signal corresponding to yaw rate and a centering spring force creating gyro natural frequencies well above the disturbance frequencies encountered. The support, jet, and nozzle fluid supplies are all incorporated into the power steering supply circuit.
