Fluidic thruster control and method

Abstract: A fluidic thruster control system and method for guided missiles and the like, which utilizes a fluidic jet interaction device for controlling a downstream fluidic vortex amplifier to modulate exhaust flow through thrust nozzles.

Fluidic angular rate sensor with integrated impulse jet pump assembly

Abstract: An angular rate sensor includes a unitary structure impulse pump for providing fluid under pressure, at a constant rate of flow, to a nozzle disposed at one end of a jet chamber to form a constant flow fluid jet, the jet chamber including a pair of temperature sensitive elements disposed at the other end in such a manner as to be differentially cooled by the fluid jet in dependence on the angular rotation of the sensor.

Fluid outlet device and a method of controlling fluid flow through a nozzle

Abstract: A fluid passing through a nozzle operative on the principle of wall effect of fluidic devices is variously deflected. A pair of control valves are provided at control fluid passages for supplying control jets into the throat portion of the nozzle in order to control the deflection of fluid flowing therethrough. A continuous straightforward flow is generated by simultaneous opening of said control valves.

Piezoelectric transducer with signal actuated function - uses electric control signal to switch fluidic pressure flow from one output to another one

Abstract: An electric signal actuates a control member, in order to trigger a transducer switching function in relation to the appearance or quenching of a fluidic output signal. The pressurised fluidic flow is affected in an inlet zone by a fluidic interference magnitude, produced by the electric signal, in such a manner that the pressurised flow is switched from one transducer outlet to the other. The fluidic interference magnitude is pref. generated by an electrically energisable oscillation generator (8), comprising a diaphragm (9) closing a resonator chamber (15). The diaphragm surface is connected with an oscillator crystal (10), while a turbulence amplifier (1) is used as a fluidic element. The amplifier and the oscillator may form an integral unit, the amplifier having an inlet zone (4), through which flow the pressurised fluid from a connecting union (P).
