Development of an advanced gas turbine engine diagnostics, prognostics, and health management system

燃气轮机发动机(GTE)已广泛应用于民用和国防领域，用于发电，对许多工业工厂、飞机和重型车辆的运行至关重要。任何意想不到的发动机故障都可能代价高昂，甚至是灾难性的。因此，为了全面了解发动机系统的运行状态，提高运行可靠性，降低维护成本，GTE的健康状态监测和预测在工业中是非常必要的。由于其巨大的重要性，在过去的几十年里，人们对GTE健康状况监测和预测进行了广泛的研究，以此作为提供故障预警、实现预测性维护和提高系统资质的一种手段。尽管文献中提出了多种方法，但由于GTE结构的内在复杂性和操作条件的时变性，可靠地评估GTE当前和未来的健康状况在研究和工业应用中仍然是一项具有挑战性的任务。这项拟议的研究与渥太华的寿命预测技术公司(LPTi)合作，旨在开发先进的GTE诊断、预测和健康管理系统，以应对这一挑战。我们的最终目标是开发更可靠的GTE健康状况监测和预测技术和工具，以帮助加拿大公司提高资产利用率，降低GTE拥有的总成本，并保持在全球市场上的竞争力。

Gas turbine engines (GTE) have been widely used in civilian and defense sectors for generating energy and are critical to the operation of many industrial plants, aircrafts, and heavy vehicles. Any unexpected engine failure could be costly or even disastrous. GTE health condition monitoring and prediction are therefore critically needed in industries for comprehensive knowledge of engine system running status, improving operation reliability, and reducing maintenance cost. Because of their tremendous importance, extensive research has been conducted over the past decades in GTE health condition monitoring and prediction as a means to provide advance warning of failure, enable forecasted maintenance, and improve system qualification. Although a variety of methods have been proposed in the literature, reliable assessment of GTE current and future health conditions still remains a challenging task in both research and industrial applications due to the inherent complexities in GTE structures and time-varying operating conditions. Partnering with an Ottawa-based company, Life Prediction Technologies (LPTi), the proposed research is aimed to develop an advanced GTE diagnostics, prognostics, and health management system to address this challenge. Our ultimate goal is to develop more reliable techniques and tools for GTE health condition monitoring and prediction so as to help Canadian companies improve asset utilization, reduce the total cost of GTE ownership, and remain competitive in the global market.
