AbstractNot Available In this project, Foster-Miller will evaluate the likely failure modes, and the sensor and electrical signals available in the systems controllers for performing diagnostics evaluations on advanced aircraft electric actuation systems. An overall concept will be developed for a prognostics system for the electrical control and actuation systems on a More Electric Aircraft. This concept will include use of existing sensors, controller signals, and power draw signatures for prognostics. Methods for isolating the prognostics system from EMI produced by the actuators and other aircraft systems will also be investigated. Any additional sensors that may be needed for detecting specific critical failure modes will be defined. The applicability of smart sensor technology to this application will be evaluated. As part of this effort, nonlinear phase space reconstruction techniques that have been developed for vibration control and diagnostics on Navy helicopters will be investigated for their ability to define the operating regime of the aircraft and the actuator system. The ability of these techniques and other nonlinear instrument analysis techniques to provide prognostic information relative to actuator health will also be evaluated. Data on actual electromechanical actuation systems will be obtained from Sundstrand Aerospace for the feasibility evaluation.
