Propulsion system integration and optimisation

燃气轮机发动机迅速发展，为全球交通运输提供可靠、高效的商业解决方案。发动机设计过程显然对这一演变做出了很大贡献。这一过程是高度迭代的、多学科的、性质复杂的。发动机的成功取决于精心平衡的设计，该设计最好地利用了众多传统工程学科之间的相互作用，如空气动力学和结构，以及对成本、可制造性、适用性和保障性的生命周期分析。普惠加拿大(P&WC)在小型航空发动机的设计和制造方面处于世界领先地位。P&WC通常每年设计和开发10-15台发动机，这导致在过去10年中获得认证的新发动机达到创纪录的50台。为了继续这一点并满足新的市场需求，先进的设计和发动机模块设计研究可能达到每年30至50项。拟议的计划旨在部署一个全自动化和集成的P&WC涡轮系统优化器“TSO”，该优化器能够在空气动力性能、冷却流、耐用性、成本和重量之间找到最佳平衡，以实现最佳的产品性能。由此产生的“TSO”预计将产生更好的综合结果，同时减少发动机设计所需的时间。将向大学提供简化版本，以便向学生提供发动机性能、重量和成本之间的权衡知识。拟议的计划的动机来自巴黎高等技术学院(ETS)的愿景，该愿景的目标是通过与P&WC建立战略工业合作伙伴关系，加强其在推进系统方面的专业知识，以培养在整个动力装置和飞机系统的优化和集成方面拥有更多知识的新一代工程师。

The gas turbine engine has envolved rapidly to provide a reliable and efficient business solution for global transportation. The engine design process is clearly a large contributor to this evolution. This process is highly iterative, multidisciplinary and complex in nature. The success of an engine depends on a carefully balanced design that best exploits the interactions between numerous traditional engineering disciplines such as aerodynamics and structures as well as lifecycle analysis of cost, manufacturability, serviceability and supportability. Pratt & Whitney Canada (P&WC) is the world leader in the design and manufacturing of small aero-engines. P&WC typically designs and develops 10-15 engines per years, which has resulted in a record 50 new engines certified over the past ten years. To continue this and to address new market requirements, advanced design and engine module design studies could reach 30 to 50 per years. The proposed program aims to deploy a fully automated and integrated P&WC Turbine System Optimizer "TSO" that is capable of finding the optimal balance between aerodynamic performance, cooling flows, durability, cost and weight in order to achieve the best product performance. The resulting "TSO" is expected to produce better-integrated results, while providing a step reduction in engine design elapsed time. A simplified version will be made available to universities in order to provide students with knowledge of trade-off between engine performance, weight and cost. The proposed program draws motivation from the vision at École de technologie supérieure (ETS), whose aim is to strengthen its expertise in propulsion systems through a strategic industrial partnership with P&WC in order to develop a new generation of engineers with greater knowledge in optimization and integration of the entire powerplant and aircraft system.************************
