“城市空中交通工具”被誉为航空业的下一次革命。各种尺寸的原型已经飞行以演示基本飞行（悬停和爬升），但在大多数情况下没有演示完整的飞行能力，例如从垂直飞行转换为水平飞行（转换走廊）。有各种规模的车辆的建议：从专门设计用于运送货物的无人机到用于载人运输的全尺寸车辆。大多数提出的概念包括全电力推进，多个（通常是可转换的）转子（管道或非管道，反向旋转），以及广泛使用复合材料。初创公司在媒体面前高调示威寻求资金，但许多悬而未决的技术问题并没有得到解决。大型航空航天公司也加入了这场竞争。这些举措使人们更加期待，实现下一个里程碑是轻而易举的。本文旨在填补一些认识上的空白，抑制乐观情绪。它采取整体观点，以便为设计，制造和运营建立科学基础。
"Urban air vehicles" have been hailed as the next revolution in aviation. Prototypes of various sizes have been flown to demonstrate basic flight (hover and climb), but in most cases there is no demonstration of full flight capability, for example conversion from vertical to level flight (conversion corridor). There are proposals for vehicles in a wide range of scales: from drones specifically designed to deliver goods, to full size vehicles for manned transportation. Most of the concepts proposed include full electric propulsion, multiple (often convertible) rotors (ducted or un-ducted, counter-rotating), and widespread use of composite materials. Start-up companies are seeking funding with high-profile demonstrations in front of the media, but many unresolved technical problems are not been solved. Large aerospace companies have joined the fray. These initiatives are fuelling expectations that achieving the next milestone is within easy reach. This paper aims to fill some gaps in understanding and curb optimism. It takes a holistic view in order to establish a scientific basis for design, manufacturing, operations.
