  • Self-organizing control system
    Patent number: 4425614
    Abstract: The disclosure relates to a self-organizing control of advanced turbine engines wherein thrust is controlled and thrust specific fuel consumption (TSFC) is minimized by control of the fuel flow rate as well as optimization of system geometric parameters. The controller computes the net thrust error by comparing commanded thrust with an inferred or calculated thrust measurement.

  • System for nondestructive evaluation of material flaw characteristics
    Patent number: 4213183
    Abstract: The disclosure relates to a system for nondestructive evaluation (NDE) of material flaw characteristics. The NDE system, after being trained on previously-acquired experimental data, is given an assigned NDE task by the inspector and/or remote observer. This task is requested via a small keyboard on the system control unit or remotely. The system then issues detailed commands to stepping motors in its transducer-positioning mechanism (scanner) and to logic circuits in the ultrasonic (UT) pulser/receiver to establish the sequence of transducer (probe) translation and orientation changes and the frequency, pulse-width, and pulse repetition interval used to energize the probe. Shaft-position encoders in the scanning mechanism are used to insure faithful following of the commanded position/orientation sequence.

  • System for measurement of subsurface fatigue crack size
    Patent number: 4052889
    Abstract: A system for detecting and measuring subsurface fatigue cracks wherein acoustic pulse-echo data from the crack under test are manipulated to extract all acoustic characteristics by means of a Fourier operation, deconvolution and inverse Fourier operation, providing a spectral and cepstral analysis on these data and then utilizing the results of the spectral and cepstral analysis to obtain parameters which are utilized in an adaptive learning network to provide crack length measurements.

  • Non-minimum phase linear controller for hydraulic mechanisms
    Patent number: 3935523
    Abstract: The disclosure relates to a non-minimum phase linear controller which uses positive servomechanism rate feedback to control hydraulic mechanisms. The disclosure also relates to a controller comprising, in combination, a conventional linear controller and a non-minimum phase linear controller, the outputs of the combined controllers being weighted in a predetermined ratio to provide a single output control signal.
