Hybrid Control Components for Turbine Engines.
Abstract
Two types of transducers were designed, built, and tested during this program. One is an electro-hydrofluidic transducer which converts electrical energy into a hydraulic signal; the other is a pneumatic-hydrofluidic transducer which converts a pneumatic signal into a hydraulic signal. The electro-hydrofluidic transducer employs electromagnetic effects to produce a force and motion that influence a hydraulic fluid amplifier. The movement is applied to a small pin located in the interaction region of the amplifier to cause a deflection of the power jet relative to the amplifier receivers. This device has inherently low power consumption and low hysteresis. The design of the electromagnetic structure complements these features to produce a high accuracy, low power consumption interface device. The pneumatic-hydrofluidic transducer uses the same hydraulic fluid amplifier feature, with the major difference between the units being the method of moving the amplifier pin.
