The proposed research program will develop a methodology and associated mathematical models to perform effective aircraft systems architecting as an integrated part of the aircraft design process, pivotal to the development of environmentally friendly air vehicles. Background The aerospace industry has ambitious targets to contribute in the fight against climate change. To achieve this goal, novel aircraft configurations, hybrid-electric or all-electric air vehicles seem promising. However, the evaluation of the feasibility of these concepts is complex, requiring to the development of novel design and prediction methods. Within, the development of associated system architectures is essential. The system architecture (consisting of hydraulic, electric and pneumatic power systems, flight control systems, avionics systems, environmental control systems, and many more) impacts significantly the weight, vehicle shape, reliability, cost and emissions of air vehicles. For aircraft with a hybrid-electric or all-electric propulsion system, the system architecture needs to change to a more-electrical architecture, leading to system integration challenges in terms of architecture, space requirements and thermal aspects. Today, there is a gap regarding methodologies for conceptual design of aircraft systems suitable to tackle complex integration challenges of novel aircraft configurations. Advanced research is necessary. Scientific approach The research program is structured in two long term research objectives (RO): RO1 will develop novel methodologies for: (1) system architecture definition and management of design space alternatives, (2) analysis of uncertainty propagation and scenarios, (3) system architecture feasibility analysis for safety requirements. These methodologies will be integrated with a parametric conceptual sizing framework for vehicle-level system architecture evaluation and integration. RO2 will develop a library of a conceptual estimation models and technologies for novel aircraft system architectures evaluation and integration for weight, power demand, size and reliability. A bottom-up approach will be used, performing simplification while establishing physical scalability on component and system level. Significance This proposed research innovates in the field of conceptual aircraft design. New mathematical models will contribute to technological advancement in aircraft conceptual design. The HQP gap in the field of aircraft systems design in Canada will be reduced. Aircraft manufacturers, engine manufacturer, system developers or research institutions will be able to perform analysis of unconventional configurations considering the important aspect of system integration. Therefore, the conceptual design framework is crucial to mature faster more environmentally friendly air vehicle of concepts, enabling sustainable mobility, and to increase the competitiveness of the Canadian aerospace industry.

拟议的研究计划将开发一种方法和相关的数学模型，以执行有效的飞机系统架构，作为飞机设计过程的集成部分，这对于开发环保飞行器的开发至关重要。 背景 航空航天行业的目标是为反对气候变化的斗争做出贡献。为了实现这一目标，新颖的飞机配置，混合电动或全电动航空器似乎很有希望。但是，对这些概念的可行性的评估很复杂，这需要开发新颖的设计和预测方法。在内部，相关系统体系结构的开发至关重要。系统体系结构（由液压，电动和气动电源系统，飞行控制系统，航空电子系统，环境控制系统等组成），对空中车辆的重量，车辆形状，可靠性，成本和排放都显着影响。对于具有混合电动或全电推进系统的飞机，系统体系结构需要更改为更具电动的架构，从而在体系结构，空间需求和热量方面方面带来了系统集成挑战。如今，关于飞机系统的概念设计方法的差距，适合于应对新型飞机配置的复杂集成挑战。高级研究是必要的。 科学方法 该研究计划的结构是两个长期研究目标（RO）： RO1将开发出：（1）系统体系结构定义和设计空间替代方案的新方法，（2）分析不确定性传播和场景，（3）安全要求的系统架构可行性分析。这些方法将与用于车辆级系统体系结构评估和集成的参数概念大小框架集成。 RO2将开发一个库的库，用于新型飞机系统体系结构评估和整合重量，功率需求，大小和可靠性的库。将使用自下而上的方法，在组件和系统级别上建立物理可扩展性时进行简化。 意义 这项拟议的研究在概念飞机设计领域进行了创新。新的数学模型将有助于飞机概念设计的技术进步。加拿大飞机系统设计领域的HQP差距将减少。飞机制造商，发动机制造商，系统开发人员或研究机构将能够对系统集成的重要方面进行非常规配置的分析。因此，概念设计框架对于更快的概念更加环保的空中汽车，实现可持续的移动性以及提高加拿大航空航天行业的竞争力至关重要。
