中国飞行汽车与国外飞行汽车水平有多大差距?

国内很早就有探讨要做飞行汽车的,但其实大家都还刚刚起步。与国外相比,我们某一单项技术有特色,有优势,但从整体上来说,还落后不少。我们还在测试推进系统,人家的产品已经在试飞了。

为什么要造飞行汽车
记者:人类有了多种交通方式,为什么还需要飞行汽车?
张扬军:人类对自由的向往是没有止境的。正是在这种追求下,交通运输发生了多次革命,正在到来的是通用航空革命,小飞机、个人化飞行将逐渐成为重要交通方式。严格说来,飞行汽车是“通用航空器”的一种。
在路上开车,突然前面没路了,我们就会想,如果能飞起来有多好。道路越来越宽,但还是堵车,我们就会想,能不能规划出立体空中交通网?人类要摆脱这些束缚,自然而然地想着把陆空交通融合起来,在美国也有人把第四次交通革命称为建设“空中高速路”。
记者:从技术上分析,陆空交通融合不容易吧。
张扬军:汽车和航空最初是一起研究的。动力的研究最具代表性,早期飞机和汽车动力都是内燃机,后来才走向不同的道路,汽车沿着内燃机技术方向前进,航空则因高速飞行的需求发展出涡轮发动机的技术。但现在航空动力继续分叉,追求高速的一支是与航天动力融合,形成以涡轮冲压为特点的空天动力。另一支低空、低速的即通用航空则又回头与汽车动力融合,朝电动化方向发展。汽车和通用飞机现在只是在发动机等零部件技术上是相通的,但往后发展,就会有整机产品把它们合二为一,这就是飞行汽车。

It has long been discussed in the country to be a flying car, but in fact everyone is just getting started. Compared with foreign countries, one of our individual technologies has its own characteristics and advantages, but overall, it still lags behind. We are still testing the propulsion system, and people's products are already flying.

Why do you want to build a flying car?
Reporter: Humans have multiple modes of transportation. Why do you need to fly a car?
Zhang Yangjun: Humanity's longing for freedom is endless. It is in this pursuit that transportation has undergone many revolutions, and the general aviation revolution is coming. Small aircraft and personalized flight will gradually become important modes of transportation. Strictly speaking, a flying car is a type of "general aircraft."
Driving on the road, suddenly there is no way ahead, we will think, how good it is to fly. The road is getting wider and wider, but it is still a traffic jam. We will think, can we plan a three-dimensional air traffic network? Human beings must get rid of these constraints and naturally think of integrating land and air traffic. In the United States, some people refer to the fourth traffic revolution as building an "air highway."
Reporter: From a technical analysis, it is not easy to integrate land and air traffic.
Zhang Yangjun: Cars and aviation were originally studied together. The study of power is the most representative. Early aircraft and automobile power were internal combustion engines. Later, they went to different roads. The cars followed the direction of internal combustion engine technology, and aviation developed the technology of turbine engines due to the demand for high-speed flight. But now aviation power continues to fork, and the pursuit of high-speed is to integrate with aerospace power to form an aerospace power characterized by turbo stamping. Another low-altitude, low-speed general-purpose aviation is turning back to the power of the car and moving toward electrification. Automobiles and general-purpose aircraft are now only connected in terms of engine and other components, but in the future, there will be a whole product that combines them into one. This is the flying car.
