Aircraft manufacturers strive to improve their efficiency and effectiveness of the development processes. Increasing maturity and implementing more disciplinary analyses in the conceptual design are key enablers to reduce costly design iterations in later design stages. Therefore, the aircraft's conceptual design employs more and more multidisciplinary design analysis and optimization (MDAO) frameworks, which require automation of the involved disciplinary analysis. Recent aircraft conceptual MDAO frameworks integrate geometrical modellers, but these are generally limited to represent external aircraft geometry. Computer-Aided Design (CAD) software enables the generation of three-dimensional (3D) models that can provide geometrical parameters to most of the disciplines involved in aircraft conceptual design. Moreover, using an advanced CAD system early in conceptual design allows a seamless transition to more detailed design phases. For novel aircraft configuration and more electric, hybrid electric, and fully electric aircraft architectures, systems integration in the conceptual design is essential. To integrate aircraft systems and subsystems analyses within the MDAO frameworks, aircraft geometric or CAD modellers need to follow suit. This paper proposes a framework to describe CAD modellers' integration into MDAO environments for use in the conceptual design phase. This paper also formalizes the interactions between the disciplines and a CAD modeller within MDAO workflows and provides requirements for automated systems and subsystems analyses. Therefore, the presented work enables integrating novel disciplines, such as thermal, maintenance, safety, and electromagnetic compatibility (EMC) analyses, into the aircraft conceptual design phase. A case study covering the thermal analysis of an aircraft equipment bay demonstrates the effectiveness of the proposed MDAO framework.

通过参数CAD建模器改善飞机的概念​​设计–飞机系统热分析的案例研究

飞机制造商努力提高其开发过程的效率和有效性。在概念设计中增加成熟度并进行更多的学科分析是减少后期设计阶段中昂贵的设计迭代的关键推动力。因此,飞机的概念​​设计采用了越来越多的多学科设计分析和优化(MDAO)框架,这需要对涉及的学科分析进行自动化。最近的飞机概念性MDAO框架集成了几何建模器,但通常仅限于表示外部飞机几何形状。计算机辅助设计(CAD)软件可生成三维(3D)模型,该模型可为飞机概念设计涉及的大多数学科提供几何参数。而且,在概念设计的早期使用先进的CAD系统可以无缝过渡到更详细的设计阶段。对于新颖的飞机配置以及更多的电动,混合电动和全电动飞机架构,概念设计中的系统集成至关重要。为了将飞机系统和子系统分析集成到MDAO框架中,飞机几何或CAD建模者需要紧随其后。本文提出了一个框架,用于描述将CAD建模人员集成到MDAO环境中,以用于概念设计阶段。本文还规范了MDAO工作流程中各学科与CAD建模器之间的交互,并提供了对自动化系统和子系统分析的要求。因此,目前的工作可以整合新颖的学科,例如热学,维护,安全,和电磁兼容性(EMC)分析,进入飞机概念设计阶段。涵盖飞机设备舱的热分析的案例研究证明了所提出的MDAO框架的有效性。
