摘要： A microwave position sensing system includes a plurality of target components that each move between multiple positions. A microwave generator produces a microwave frequency signal. A divider receives the microwave frequency signal and splits the microwave frequency signal into a plurality of position sensing signals. The position sensing signals are respectively sent to the plurality of target components to determine a position of each of the target components. Each position sensing signal may also be calibrated. In one example, first and second frequencies are transmitted through a common wave guide. The first frequency is reflected prior to reaching the target component to produce a calibration signal. The second signal, which is used to detect the position of the target component, is calibrated using the first frequency.

摘要： A rotor blade measurement system includes a microwave source and a probe. A directional coupler is attached to the source and the probe. A detector is attached to the directional coupler. The probe directs a microwave signal toward a rotor such that during rotation the rotor blade will pass through the path of the microwave signal. As the rotor blade passes the microwave signal is reflected back to the probe. The directional coupler separates the original microwave signal and the reflected signal. The detector then determines the energy level of the reflected signal. As each rotor blade passes the microwave signal it generates a reflected signal that can be analyzed over time. From the length and shape of the waveform of the reflected signal the amount of twisting and flutter in a rotor blade can be determined.

摘要： A system and method for determining thermal growth of motor or engine parts to thereupon control the clearance of motor or engine fan blades is disclosed herein. In addition, a system and method for monitoring the health of a turbine engine, its components and sub-components is also described herein. The system(s) and method(s) described herein permit continuous monitoring during the life of the engine for radial clearances and blade and rotor vibration problems, which will assist in correcting and retaining performance for a longer on-wing time in operation. In addition, inconsistent engine-to-engine performance variations due to component tolerances, engine operation characteristics, and operation during extremes in ambient temperatures can be eliminated or significantly minimized when employing the system(s) and method(s) described herein.
