Methodologies and tools for virtual design and testing of advanced flight control systems

随着电传操纵（FBW）飞行控制技术在运输机领域的成熟，下一个合乎逻辑的发展是在飞行控制系统中引入更多的功能。例如，在庞巴迪公司研制的第一架FBW飞机C系列上，副翼在起飞构型中对称地向下下垂几度，以优化爬升性能的升力分布。飞行控制的多功能使用具有提高未来飞机燃油效率的巨大潜力，从而有助于减少航空的环境足迹。然而，这种先进的飞行控制系统的特点是比当前系统的复杂性高得多，并且也为潜在的架构选择开辟了非常大的设计空间。因此，需要研究新的方法和工具，以提高这种先进飞行控制系统开发过程的效率和有效性。 与庞巴迪合作的项目将研究这些新方法和工具，并通过在三个领域推进虚拟设计和虚拟测试的最新技术，为加拿大下一代飞机实现新型飞行控制系统架构做出贡献：（1）基于模型的系统工程（MBSE），（2）基于模型的安全评估（MBSA）和（3）基于模型的设计（MBD）。这些新的方法将导致先进的飞行控制系统的发展，减少加拿大设计的飞机的环境足迹，提高庞巴迪开发过程的成本效益，以确保持续的国际竞争力。

With the technology of fly-by-wire (FBW) flight controls now well established in the sector of transport aircraft, the next logical evolution is to introduce more multi-functionality in the flight control system. For instance on the CSeries, the first FBW aircraft developed by Bombardier, the ailerons are drooped symmetrically a few degrees down in the take-off configuration to optimize the lift distribution for climb performance. The multi-functional use of flight controls has significant potential of increasing the fuel efficiency of future aircraft and thus contribute to reducing the environmental footprint of aviation. However, such advanced flight control systems feature significantly higher complexity than current systems and are also opening a very large design space of potential architecture options. New methodologies and tools therefore need to be researched to increase the efficiency and effectiveness of the development process for such advanced flight control systems. The presented project with Bombardier will research such new methodologies and tools and will contribute to bringing novel flight control system architectures to fruition in the next generation of aircraft in Canada, by advancing the state-of the art of virtual design and virtual testing in three areas: (1) model-based systems engineering (MBSE), (2) model-based safety assessment (MBSA) and (3) model-based design (MBD). These new methodologies will lead to the development of leading edge flight control systems, reducing the environmental footprint of Canadian designed aircraft and increasing the cost effectiveness of Bombardier's development process to ensure sustained international competitiveness.
