    Abstract: Apparatus for sensing acceleration and generating an analog-type pressurized fluid signal proportional to the magnitude of the associated acceleration event. A friction-free spring-mass device in the form of a flexure-mounted inertial mass includes a hollow, elongated spring member of the cantilever beam type having a first end rigidly fixed in position and a second unsupported end upon which the acceleration-sensitive inertial mass is mounted for sensing linear motion acceleration. The hollow portion of the spring member issues a fluid jet from the second unsupported end directed at fluid receivers, the flexure of the spring member causing distribution of the jet between the receivers in proportion to the magnitude of the acceleration. Angular motion acceleration is sensed by utilizing a cylindrical inertial mass connected along its longitudinal axis to two torsional spring members rigidly fixed in position at their far ends such that the cylindrical mass is subject to rotation in the presence of an angular motion acceleration.

    Abstract: THE DISCLOSURE SHOWS FLUIDIC MEANS FOR DETECTING INCIPIENT STALL OF AN AXIAL FLOW COMPRESSOR EMPLOYED IN A GAS TURBINE ENGINE. FUEL FLOWS IS MODIFIED AS A RESULT OF SUCH DETECTION TO MOVE THE OPERATING POINT OF THE COMPRESSOR AWAY FROM A STALL CONDITION. RAPID FLUCTUATIONS IN THE OUTPUT PRESSURE OF THE COMPRESSOR, PREFERABLY IN THE RANGE OF 250 TO 1,000 CYCLES PER SECOND, ACTUATE FLUIDIC SYSTEM TO CAUSE THE CHANGE IN FUEL FLOW.

    Abstract: Control pressure to a hydraulic control valve is supplied by a fluid amplifier. Pressure feedback paths are provided to the amplifier inputs from both the amplifier outputs and the hydraulic control valve outlets so as to utilize sufficient pressure of the fluid amplifier to overcome friction within the control valve assembly. The amplifier and associated feedback paths further constrain the system output differential pressure to be linearly proportional to the system input differential pressure.

    Abstract: A VARIABLE AREA VALVE IS INTERPOSED BETWEEN A SOURCE OF WORKING FLUID AND THE POWER NOZZLE OF A HYDRAULIC FLUID AMPLIFIER, AND ITS FLOW AREA IS CONTROLLED IN INVERSE RESPONSE TO PRESSURE CHANGES DETECTED IN A FLUID JET ISSUING FROM A REFERENCE NOZZLE. THE REFERENCE NOZZLE IS SUBSTANTIALLY IDENTICAL TO, AND IS CONNECTED IN FLUID PARALLEL WITH, THE POWER NOZZLE OF THE FLUID AMPLIFIER. FLUCTUATIONS IN THE REYNOLDS NUMBER OR VISCOSITY ASSOCIATED WITH THE WORKING FLUID ARE DIRECTLY MANIFESTED IN PRESSURE CHANGES IN THE JET ISSUING FROM THE POWER NOZZLE AND THUS IN GAIN CHANGES IN THE FLUID AMPLIFIER. PRESSURE CHANGES DETECTED IN THE REFERENCE JET ARE DIRECTLY RELATED TO ANY PRESSURE CHANGES WHICH OCCUR IN THE POWER JET OF THE FLUID AMPLIFIER AND SERVE TO COMPENSATE FOR THE LATTER BY MOVING THE VARIABLE AREA VALVE SO AS TO INCREASE OR DECREASE THE PRESSURE OF THE WORKING FLUID SUPPLIED TO THE FLUID AMPLIFIER.
