An output system (186) for a fluidic angular rate sensor (74, 314) or other device having two fluid pressure outputs is used to convert the dual outlet pressure signals to a pair of oscillating electrical signals whose relative frequency differential is very accurately indicative of the outlet pressure differential of the sensor or other device. The dual outlets of the sensor or other device are fluidically coupled to the control ports of the first amplifier (256) in a cascaded series of fluidic proportional amplifiers (256, 258, 260). The outlet ports of the terminal amplifier (260) are coupled to the inlet ports of a pair of fluidic oscillators (262, 264). A pair of microphone type-pressure-to-electric transducers (266, 268) are driven by the oscillators to produce the oscillating electrical signals. The system is applicable in the field of navigational guidance systems (10) for deriving pulsed electrical angular rate signals representing rotations about up to three control axes utilising fluidic angular rate sensors (74, 314) in place of conventional mechanical rate gyroscopes. |

| FLUID VORTEX APPARATUS COMPRISING A A HOUSING ENCLOSING A VORTEX CHAMBER, A PRIMARY COUPLING ELEMENT SURROUNDING THE VORTEX CHAMBER, A CENTRAL FLUID OUTLET FROM THE VORTEX CHAMBER, AND SECONDARY COUPLING MEANS LOCATED WITHIN THE VORTEX CHAMBER BETWEEN THE PRIMARY COUPLING ELEMENT AND THE CENTRAL OUTLET. THE PRIMARY COUPLING ELEMENT IS STRUCTURE TO INTRODUCE FLUID INTO THE VORTEX CHAMBER SO THAT IT HAS SUBSTANTIALLY NOT RATIONAL VELOCITY WITH RESPECT TO THE CHAMBER HOUSING, FLUID WITHIN THE VORTEX CHAMBER ACQUIRING A ROTATIONAL VELOCITY WITH RESPECT TO THE HOUSING IN RESPONSE TO INPUT STIMULII. THE SECONDARY COUPLING MEANS MODIFIES ANY RATIONAL FLOW PATTERN WITHIN THE VORTEX CHAMBER SO AS TO PRODUCE A CHARACTERIZED TIME-VARYING ROTATIONAL FLOW PATTERN IN THE FLUID OUTLET. A SENSOR IN THE OUTLET PRODUCES A SIGNAL INDICATIVE OF THE RATIONAL VELOCITY OF FLOW ABOUT THE AXIS OF THE OUTLET, THEREBY RESULTING IN A CHARACTERIZED RESPONSE TO THE INPUT STIMULII.

| Fluid vortex apparatus including a vortex chamber, a characterized coupling element comprising a stack of spaced annular discs for introducing fluid into the vortex chamber, and a fluid outlet from the vortex chamber. The coupling element is characterized so that different portions of the fluid are introduced into the vortex chamber at different distances from the outlet, and are thus subject to different transfer characteristics in traversing the chamber. The annular discs in the coupling element are separated by predetermined small distances chosen to provide great viscous coupling between the discs and the fluid flowing therebetween. A sensor associated with the outlet passage produces a signal indicative of a summation of the modifications to rotational velocity of flow about the axis of the outlet, thereby resulting in a characterized response to input stimuli.

| A fluid vortex includes: a cylindrical chamber; a first inlet for the main fluid into the chamber; a control inlet for the tangential introduction of a control fluid into the chamber in order to impart to the main fluid travelling inside the chamber a rotary motion; and an axial outlet for the fluid escaping from the chamber. According to the present invention, a body having substantially a revolution shape and without any rigid mechanical connection with the vortex is placed in the vortex outlet as a load therefor.

| 1,119,489. Speedometers. UNITED AIRCRAFT CORP. Dec.2, 1966 [Jan. 4, 1966], No. 53985/66. Heading G1K. [Also in Division G3] A twin vatex angular rate sensor device for sensing rotational movement of a body about an axis X as well as the direction thereof comprises a pair of chambers 10,12 adapted to induce counter-rotating vortex flow of a fluid and sensor means 32 for comparing the vortex outputs 26 for providing a signal in the event of a differential in pressure of flow from the outputs 26, the signal being used to indicate the direction and rate of angular movement of the body. Each chamber comprises a conical chamber 24 in connection with a plen chamber 22 by means of tanjential slots 30. Fluid is fed into the plenum chamber through inlets 18 and depending on the direction of rotation of the shaft the fluid in either chamber 10 or 12 is aided by this rotation so as to induce a greater pressure at one of the outlets 26. A jet of fluid is fed into channel 36 and when the shaft is stationary passes straight through tube 40. However if the pressure of flow is greater at one output than the other, the jet is deflected into one or other of the side tubes 38, 42 depending on the direction of rotation. The device may be used to measure the speed of rotation by determining the volume of fluid rising from the side tube or may be used to control or stabilize the rotation of the body. | ||||||
