在路上遭遇堵车时，不少人一定想过“要是能飞起来多好！”你知道吗，能飞的汽车即将成为现实。

飞行汽车要来了，10月就能预订

　　 据报道，近日国内一家汽车公司宣布将于10月起接受预订飞行汽车。该车为油电混合动力，配备汽车方向盘，需跑道起降，机翼采用折叠式，起飞可展开。可乘坐2人，最大飞行高度约3000米，最高飞行速度每小时160公里，空中续航能力640公里，百公里油耗11.87升。需要同时有汽车驾照和飞行驾照。按照计划，这种飞行汽车2019年开始量产，首批用户对美国开放，中国市场将视情况而定，后期将逐步发展到欧洲。

　　 近日举行的第二届全球未来出行大会上，该公司有关负责人透露了两款飞行汽车计划：第一款是适合长航程使用，需要跑道起降，明年推出；2023年将推出市内多螺旋桨垂直起降的机型，符合市内拥挤空间的起飞降落。
　　出行虽然有可能更方便，但要解决的问题还很多
　　 飞行汽车距离普通市民的生活究竟还有多远？华商报记者为此采访了长安大学汽车学院教授、博士生导师郭应时。
　　 郭教授说，近年来由于很多城市的道路拥堵问题、巨额的道路设施修建成本等，飞行汽车概念再次热了起来。飞行汽车有三个优点：第一，由二维的平面交通转化成三维立体交通，交通或更加便捷，甚至可能真正实现点对点、门到门的交通；第二，对道路设施的要求降低，对道路交叉口的要求，甚至对桥梁隧道等交通基础设施的要求都会大幅度降低；第三，有可能减少交通工具之间相互的接触碰撞几率。

　　 但郭教授表示，目前飞行汽车还面临很多问题要解决：第一是技术问题，包括轻量化、动力问题，另外这种汽车本身有两到三套的传动转换装置，会带来整个系统的可靠性问题；第二尽管飞行汽车具备飞行能力，但对道路设施还要有一些基本要求，需要有起飞降落的场地；第三，在交通规划方面，到底是按照飞行通道的模式规划，还是用局部飞禁的模式规划？第四，它到底是汽车还是飞机，该如何认定？这不仅需要国家统筹考虑，还可能需要在世界范围内研究解决。
　　系统运行、低空开放，这些问题要解决不容易
　　 “拿交通管制来说，虽然说三维空间要比二维空间大很多，但它必须要经过严格规划，否则没办法保证安全，而这本身就是非常复杂的决策与控制问题，按照现有技术能力，恐怕还无法完全满足个性化需求的离散式的交通出行规划。可以想象一下，如果城市上空每天都飞满了飞行汽车，所有人出行都依赖它，在这种模式下环保、能源消耗、公众安全以及一些涉及公众利益的问题，都没办法根本解决。”

　　 “技术、生产成本等还不是核心问题。因为技术随着需求量的增加，会逐步接近平民化，更大的问题是如何系统解决运行问题。而关于低空开放问题，我也不是特别乐观。因为我国的需求不是那么明显，即便是美国的私人飞行也是要备案的，也不是说走就走。”
　　 但郭教授同时认为，作为技术研发和技术储备，汽车生产企业或者是飞机制造商利用商业模式对飞行汽车进行一些探索是必要的。未来会有一些特殊需求，比如边远地区的个性化交通、救生搜救领域等，使用飞行汽车是有可能的。但作为城市个性化出行需求，这种出行方式的代价，不是一般老百姓能承受的。

How far can we fly from the sky?

When a traffic jam happened on the road, many people would have thought, "if only I could fly!" You know, flying cars are coming true.

The flying car is coming, and it will be booked in October.

According to reports, a domestic car company recently announced that it will receive a scheduled flight from October. The vehicle is an oil-electric hybrid, equipped with automobile steering wheel, runway take-off and landing, wing folding, take-off can be deployed. Can take 2 people, the maximum flight altitude of about 3000 meters, the highest speed of 160 kilometers per hour, air endurance 640 kilometers, 100 kilometers of fuel consumption 11.87 litres. You need both a driver's license and a flying license. According to the plan, the flying car will start production in 2019, the first users of the United States to open up, the Chinese market will depend on the situation, the latter will gradually develop to Europe.

At the 2nd Global Future Travel Conference held recently, the company's executives disclosed two plans for flying cars: the first is suitable for long voyages, which requires runway takeoff and landing, and will be launched next year; the city will launch a multi-propeller vertical takeoff and landing model in 2023, which is in line with the city's congested space takeoff and landing.

Although travel may be more convenient, there are still many problems to be solved.

How far is the flying car from the average citizen's life? The Chinese business reporter interviewed Guo Yingshi, a professor and a doctoral tutor of Chang'an University automotive college.

Professor Guo said that in recent years, the concept of flying automobiles has become hot again because of road congestion in many cities and huge construction costs of road facilities. Flying vehicles have three advantages: first, they can be converted from two-dimensional plane traffic to three-dimensional three-dimensional traffic, which is more convenient, and may even realize point-to-point and door-to-door traffic; second, the requirements for road facilities are reduced, for road intersections, and even for traffic infrastructure such as bridges and tunnels. There will be a significant reduction; third, it is possible to reduce the probability of collision between vehicles.

But Professor Guo said that there are still many problems to be solved: first, technical problems, including lightweight, power problems, and the vehicle itself has two or three sets of transmission and conversion devices, will bring the reliability of the entire system; second, although the flying vehicle has the ability to fly, but for road facilities. There are also some basic requirements, the need for take-off and landing venues; third, in terms of traffic planning, in accordance with the mode of flight corridor planning, or with the mode of local flight ban planning? Fourth, whether it is a car or an airplane, how to identify it? This requires not only the overall consideration of the state, but also the need to study and solve it worldwide.

System operation and low altitude opening are not easy to solve.

"Take traffic control for example, although the three-dimensional space is much larger than the two-dimensional space, but it must be strictly planned, otherwise there is no way to ensure safety, and this itself is a very complex decision-making and control issues, according to the existing technical capacity, I am afraid, can not fully meet the individual needs of discrete traffic travel. Plan. Imagine if the city was filled with flying cars every day, and everyone depended on it for their travel. In this mode, environmental protection, energy consumption, public safety and some issues of public interest could not be fundamentally solved.

"Technology, production costs and so on are not the core issues. Because technology will gradually approach civilianization as demand increases, the bigger problem is how to systematically solve operational problems. I am not particularly optimistic about the opening of low altitude. Because the demand in our country is not so obvious, even private flights in the United States are to be documented, not to say go away.

But Professor Guo also believes that as a technology research and development and technology reserve, automobile manufacturers or aircraft manufacturers to use the business model of flying cars for some exploration is necessary. There will be some special needs in the future, such as personalized transportation in remote areas, life-saving search and rescue areas, the use of flying cars is possible. However, as the individualized travel demand of the city, the cost of this mode of travel is not affordable to ordinary people.（文来源：飞行汽车feiauto）www.feiauto.com
