飞行汽车运输系统：进展、技术与挑战
Flying Car Transportation System: Advances, Techniques, and Challenges
摘要：
自从运输系统发展以来，人类已经利用地面、地下和高空空间来进行运输。然而，随着近几十年来人口增长和快速城市化的负担日益加重，公共交通系统和货运交通承受着巨大的压力，使地方政府和经济紧张。工程师和研究人员已经开始重新审视，建议和开发未充分利用的近地面空间（NGS）用于交通目的。例如，飞行汽车并不是一个全新的想法，它旨在解决交通拥堵问题，并通过利用无人驾驶的NGS来缓解现有城市交通网络的压力。飞行汽车与传统的地面交通系统不同，传统的地面交通系统完全受到其物理空间的限制，例如轨道上的火车或道路上的汽车。飞行汽车不会占用或争夺空中交通用于长途运输的高空空间。然而，显然缺乏关于飞行汽车和飞行汽车运输系统（FCTS）的具体文献，本文旨在通过描述FCTS的现代进步，技术和挑战来解决这一问题。我们探讨新固网服务运输的本质，并提出有用的建议，以促进固网服务的建造和商业化。我们首先介绍了对NGS运输日益增长的需求，并讨论了使用飞行汽车的优势。接下来，我们从历史时间轴和技术发展的角度简要概述了飞行汽车的发展历史。然后，我们讨论和比较了飞行汽车的设计现状，包括起飞/着陆（TOL）模式，驾驶员模式，操作模式和动力类型。
英文摘要：
Since the development of transport systems, humans have exploited ground-level, below-ground, and high-altitude spaces for transportation purposes. However, with the increasing burden of expanding populations and rapid urbanization in recent decades, public transportation systems and freight traffic are suffering huge pressure, plaguing local governments and straining economies. Engineers and researchers have started to re-examine, propose, and develop the underused near-ground spaces (NGS) for transportation purposes. For instance, flying cars, which are not a totally novel idea, aim at solving the traffic congestion problem and releasing the strains on existing city transport networks by utilizing unoccupied NGS. Flying cars differ from traditional grounded transportation systems that are entirely limited by their physical space, such as trains on tracks or automobiles on roads. Flying cars do not occupy or compete for high-altitude spaces used by air traffic for long-distance transfer. However, there is a clear lack of specific literature on flying cars and flying car transportation systems (FCTS), which this paper aims to address by describing modern advances, techniques, and challenges of FCTS. We explore the inherent nature of NGS transportation and devise useful proposals to facilitate the construction and commercialization of FCTS. We begin with an introduction to the increasing need for NGS transportation and we address the advantages of using flying cars. Next, we present a brief overview of the history of the development of flying cars in terms of the historic timeline and technique development. Then, we discuss and compare the state of the art in the design of flying cars, including the take-off \& landing (TOL) modes, pilot modes, operation modes, and power types, ...
