A laminar jet angular rate sensor senses inertial angular rate in flight control and stabilization systems for aircraft and other vehicles. The sensor utilizes fluid as a power source and may be interfaced directly with fluid powered actuators for closed loop rate stabilization of the vehicle. To be practical, the rate sensor must exhibit consistent operation over the side range of supply fluid temperatures seen in a typical application. This invention involves apparatus for providing constant sensor gain over a wide range of fluid viscosity conditions. To achieve this, the pressure drop across the rate sensor is varied proportional to supply fluid viscosity to overcome viscous momentum losses in the jet and provide a constant gain characteristic. The specific apparatus of the invention utilizes a pressure regulator with a fluid viscosity sensor to accurately provide the required supply pressure proportional to fluid viscosity schedule.
