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一个组成部分，对环境友好型飞行器的发展至关重要。航空航天业有雄心勃勃的目标，为应对气候变化做出贡献。为了实现这一目标，新型飞机结构、混合动力或全电动飞行器似乎大有希望。然而，这些概念的可行性评估是复杂的，需要开发新的设计和预测方法。在内部，相关系统架构的开发是必不可少的。系统架构（包括液压、电力和气动动力系统、飞行控制系统、航空电子系统、环境控制系统等）对飞行器的重量、外形、可靠性、成本和排放产生了重大影响。对于采用混合动力或全电力推进系统的飞机，系统架构需要转变为更电气的架构，从而在架构、空间要求和热方面带来系统集成挑战。今天，关于飞机系统的概念设计方法，适用于解决新飞机配置的复杂集成挑战，存在差距。先进的研究是必要的。该研究计划分为两个长期研究目标（RO）： RO1将开发新的方法：(1)系统架构定义和设计空间替代方案的管理，(2)不确定性传播和场景的分析，(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架构评估和集成的参数化概念尺寸框架集成。RO2将开发一个概念估算模型和技术库，用于新型飞机系统架构的评估和集成，包括重量、功率需求、尺寸和可靠性。将使用自底向上的方法，在组件和系统级别建立物理可伸缩性的同时执行简化。意义本研究在概念飞机设计领域具有创新意义。新的数学模型将有助于飞机概念设计的技术进步。加拿大在飞机系统设计领域的HQP差距将会缩小。飞机制造商、发动机制造商、系统开发商或研究机构将能够考虑到系统集成的重要方面，对非常规配置进行分析。因此，概念设计框架对于更快地成熟更环保的飞行器概念，实现可持续的机动性，并提高加拿大航空航天工业的竞争力至关重要。

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.
