Sensor Validation for Turboshaft Engine Torque Sensors

We propose a method that specifically addresses the requirement for helicopter engine torque sensor validation by integrating the engine component level model, model reduction techniques, and real-time parameter estimation algorithms. The method starts with a component level turboshaft model. Component degradations are considered. Model reduction techniques are proposed to construct a simplified engine model to design a health parameter estimator to estimate the evolution of health parameters using sensor measurements. Finally, the estimated health parameters and states of the engine are used to determine the engine torque. In collaboration with Honeywell, APRI has assembled a multidisciplinary team with all of the requisite experience to perform the proposed research.
