Evaluation of High-Temperature Pressure Sensors for Engine Optimization

点击翻译按钮获取中文摘要

On-the-fly measurement of dynamic operating pressure in jet engines is important for optimizing fuel usage and reducing greenhouse gas emissions, but is challenging because of the extreme temperatures present in a running engine. Fibos Inc. has developed an optical pressure transducer system (UHT-PT) that is expected to have much higher temperature resistance than conventional sensors used in the aviation industry. This project seeks to optimize the UHT-PT sensor system in this extreme environment, by determining optimal sensor placement and routing, measuring the heat resistance, longevity, and stability of the sensor system, and comparing performance to conventional sensors and theoretical models. Technical leadership will be provided by faculty from Centennial College's School of Engineering Technology and Applied Science and School of Transportation, in conjunction with Fibos technical staff. This project will directly support Fibos strategic technology development prior to commercial validation on larger jet engines.
