MTU Aero Engines is Germany's leading aircraft engine manufacturer and an established global player in the industry. The company engages in the design, development, manufacture, marketing and support of commercial and military aircraft engines in all thrust and power categories and stationary gas turbines. MTU Maintenance Canada is the North American member of the MTU Maintenance network of companies, which represents the largest provider of independent commercial airplane engine services worldwide. In order to maintain and improve their level of competence in combustion technology MTU Maintenance Canada and MTU Aero Engines want to support financially the research of Prof. W. Kendal Bushe and his students and to offer their expertise and advise throughout the process. Mostly the expertise in combustion research resides with MTU Munich, but there have been recent efforts to transfer part of that knowledge into Canada. With upcoming new maintenance contracts for MTU Canada has the ambition to develop and implement new and innovative repair methods for various aero engine components. This will enable a sustainable maintenance strategy for the years to come. To understand and evaluate the effects of the high temperatures in and near the combustion chamber, the improvement of qualitative and quantitative predictions using combustion simulation is essential. The research group under Dr. Bushe offers the expertise in demand and an innovative alternative methodology, the Conditional Source-term Estimation (CSE) combustion model, which uses significantly less computational resources than other methods. Further, Dr. Bushe and his PhD student, Graham Hendra, have proposed a new, closely related model which they are naming the Uniform Conditional State model; this new approach will allow for more flexibility with respect to the way combustion chemistry is modelled, which should allow for incorporating arbitrarily complex chemical kinetic mechanisms, such that combustion of a much wider range of fuels can be simulated. These approaches will provide a tool which will enable MTU to develop new, sustainable maintenance strategies.

MTU航空发动机公司是德国领先的飞机发动机制造商，也是该行业的全球知名企业。该公司从事所有推力和功率类别的商用和军用飞机发动机以及固定式燃气轮机的设计、开发、制造、营销和支持。MTU Maintenance Canada是MTU Maintenance公司网络的北美成员，代表着全球最大的独立商用飞机发动机服务提供商。为了保持和提高他们在燃烧技术方面的能力水平，MTU维修加拿大公司和MTU航空发动机公司希望在财政上支持W。肯达尔布什和他的学生，并提供他们的专业知识和建议，在整个过程中。燃烧研究方面的专业知识主要由MTU慕尼黑提供，但最近已努力将部分知识转移到加拿大。随着即将到来的新的维修合同的MTU加拿大有雄心开发和实施新的和创新的维修方法，为各种航空发动机部件。这将使未来几年的可持续维护战略成为可能。为了理解和评估燃烧室内部和附近的高温的影响，使用燃烧模拟来改进定性和定量预测是必不可少的。Bushe博士领导的研究小组提供了需求方面的专业知识和创新的替代方法，即条件源项估计（CSE）燃烧模型，该模型使用的计算资源比其他方法少得多。此外，Bushe博士和他的博士生Graham Hendra提出了一个新的密切相关的模型，他们将其命名为均匀条件状态模型;这种新方法将允许在燃烧化学建模方式方面具有更大的灵活性，这应该允许纳入任意复杂的化学动力学机制，以便可以模拟更广泛的燃料燃烧。这些方法将提供一种工具，使MTU能够制定新的、可持续的维护战略。
