This work deals with the problem of estimating the turnaround time in the early stages of aircraft design. The turnaround time has a significant impact in terms of marketability and value creation potential of an aircraft and, for this reason, it should be considered as an important driver of fuselage and cabin design decisions. Estimating the turnaround time during the early stages of aircraft design is therefore an essential task. This task becomes even more decisive when designers explore unconventional aircraft architectures or, in general, are still evaluating the fuselage design and its internal layout. In particular, it is of paramount importance to properly estimate the boarding and deboarding times, which contribute for up the 40% to the overall turnaround time. For this purpose, a tool, called SimBaD, has been developed and validated with publicly available data for existing aircraft of different classes. In order to demonstrate SimBaD capability of evaluating the influence of fuselage and cabin features on the turnaround time, its application to an unconventional box-wing aircraft architecture, known as PrandtlPlane, is presented as case study. Finally, considering standard scenarios provided by aircraft manufacturers, a comparison between the turnaround time of the PrandtlPlane and the turnaround time of a conventional competitor aircraft is presented.

这项工作涉及在飞机设计的早期阶段估计周转时间的问题。周转时间对飞机的适销性和价值创造潜力具有重大影响，因此，它应被视为机身和机舱设计决策的重要驱动因素。因此，在飞机设计的早期阶段估计周转时间是一项必不可少的任务。当设计师探索非常规的飞机架构，或者一般来说，仍在评估机身设计及其内部布局时，这项任务变得更加具有决定性。特别是，正确估计登机和下机时间至关重要，这占总周转时间的 40%。为此，一个名为 SimBaD 的工具，已针对不同级别的现有飞机使用公开数据进行开发和验证。为了展示 SimBaD 评估机身和机舱特征对周转时间的影响的能力，将其应用于非常规箱翼飞机架构（称为 PrandtlPlane）作为案例研究。最后，考虑飞机制造商提供的标准场景，比较了 PrandtlPlane 的周转时间和传统竞争对手飞机的周转时间。以案例研究的形式呈现。最后，考虑飞机制造商提供的标准场景，比较了 PrandtlPlane 的周转时间和传统竞争对手飞机的周转时间。以案例研究的形式呈现。最后，考虑飞机制造商提供的标准场景，比较了 PrandtlPlane 的周转时间和传统竞争对手飞机的周转时间。
