Several well-established best practices and reliable tools have been developed along the years to support aircraft conceptual and preliminary design. In this context, one of the most widely used tool is the Matching Chart (MC), a graphical representation of the different performance requirements (curves representing the thrust-to-weight ratio (T/W) requirement as function of the wing loading (W/S)) for each mission phase. The exploitation of this tool allows the identification of a feasible design space as well as the definition of a reference vehicle configuration in terms of maximum thrust, maximum take-off weight, and wing surface since the very beginning of the design process. Although the tool was originally developed for conventional aircraft, several extensions and updates of the mathematical models have been proposed over the years to widen its application to innovative configurations. Following this trend, this paper presents a further evolution of the MC model to support the conceptual design of high-speed transportation systems, encompassing supersonic and hypersonic flight vehicles. At this purpose, this paper reports and discusses the updates of the methodology laying behind the generation of the MC for high-speed transportation. Eventually, the results of the validation of the updated methodology and tool are reported, using as case study, the STRATOFLY MR3 vehicle configuration, a Mach 8 antipodal civil transportation system, currently under development within the H2020 STRATOFLY project.

创新的多重匹配图方法支持高超音速飞行器的概念设计

多年来,已经开发了几种完善的最佳实践和可靠的工具来支持飞机的概念​​和初步设计。在这种情况下,最广泛使用的工具之一是匹配图 (MC),它是不同性能要求的图形表示(代表推重比 (T/W) 要求作为机翼载荷函数的曲线) W/S)) 用于每个任务阶段。从设计过程的一开始,利用该工具就可以确定可行的设计空间,并根据最大推力、最大起飞重量和机翼表面定义参考车辆配置。虽然该工具最初是为常规飞机开发的,多年来,已经提出了数学模型的几种扩展和更新,以将其应用范围扩大到创新配置。遵循这一趋势,本文提出了 MC 模型的进一步演变,以支持高速运输系统的概念设计,包括超音速和高超音速飞行器。为此,本文报告并讨论了高速运输 MC 生成背后的方法论的更新。最后,报告更新方法和工具的验证结果,使用案例研究,STRATOFLY MR3 车辆配置,马赫 8 对足民用运输系统,目前正在 H2020 STRATOFLY 项目中开发。本文介绍了 MC 模型的进一步演变,以支持高速运输系统的概念设计,包括超音速和高超音速飞行器。为此,本文报告并讨论了高速运输 MC 生成背后的方法论的更新。最后,报告更新方法和工具的验证结果,使用案例研究,STRATOFLY MR3 车辆配置,马赫 8 对足民用运输系统,目前正在 H2020 STRATOFLY 项目中开发。本文介绍了 MC 模型的进一步演变,以支持高速运输系统的概念设计,包括超音速和高超音速飞行器。为此,本文报告并讨论了高速运输 MC 生成背后的方法论的更新。最终,报告更新方法和工具的验证结果,使用案例研究,STRATOFLY MR3 车辆配置,一个马赫 8 对足民用运输系统,目前正在 H2020 STRATOFLY 项目中开发。本文报告并讨论了高速运输 MC 生成背后的方法论的更新。最终,报告更新方法和工具的验证结果,使用案例研究,STRATOFLY MR3 车辆配置,一个马赫 8 对足民用运输系统,目前正在 H2020 STRATOFLY 项目中开发。本文报告并讨论了高速运输 MC 生成背后的方法论的更新。最后,报告更新方法和工具的验证结果,使用案例研究,STRATOFLY MR3 车辆配置,马赫 8 对足民用运输系统,目前正在 H2020 STRATOFLY 项目中开发。
