Gas Turbine Operation and Maintenance Enhancement

这项提案所涵盖的工作建立在加拿大皇家军事学院和标准航空公司之间现有的合作基础上。它寻求利用和扩展他们的工程研究和仪表开发的劳斯莱斯，艾利森模型-250涡轴发动机。这种非常受欢迎的主力在世界各地使用了几十年，有15个变种。其坚固的设计使其成为性能监测和长期维修、维护和大修(MRO)计划的工程创新潜力的良好候选者。已确定正常运行的一些特征以及运行使用的有害影响，以及已批准的修复技术。建议的工作重点放在热点部分。具体地说，有必要探索燃烧系统的不稳定，并调查不令人满意的模式因素和不均匀的涡轮喷嘴劣化。为评估维修方案而开发的技术和定制设计的仪器开发已经到位，以利用迄今的研究。这是一项多阶段、平行的免费活动，旨在加强StandardAero作为全球主要MRO组织的能力，为其客户提供增值工程服务，并为该项目提供高质量的研究生流，最终为加拿大的燃气轮机行业提供服务。

The work covered by this proposal builds on an existing collaboration between the Royal Military College of Canada and StandardAero of Winnipeg, MB. It seeks to take advantage of, and extend their engineering research and instrumentation developments for the Rolls Royce, Allison Model-250 turboshaft engine. This very popular workhorse has 15 variants over decades of use around the world. Its robust design makes it a good candidate for performance monitoring, and engineering innovation potential to its long-standing programmes of repair, maintenance and overhaul (MRO). Some characteristics of normal operation as well as deleterious impacts of operational use, and approved repair techniques have been identified. The focus of the work proposed is on the hot section. Specifically, there is a need to explore unsteadiness in the combustion system and to investigate unsatisfactory pattern factors and uneven turbine nozzle deterioration. Technologydeveloped for the evaluation of repair schemes and custom-designed instrumentation developments are in place to capitalize on the research to date. It is a multi-phase, parallel suite of complimentary activities intended to enhance the ability of StandardAero, as a major global MRO organization, to offer value-added engineering services to their clients and to deliver a high quality stream of graduate students to the project and eventually to the gas turbine industry in Canada.
