Have you ever imagined flying over the city in an air taxi that has no pilot? Do you believe it can take you from place to place in minutes? It sounds like science fiction, right? Well, not anymore.
An electric vertical take-off and landing(eVTOL) aircraft, also known as an air taxi, completed its first intercity demonstration flight(城际示范飞行) in Guangdong on February 27. The eVTOL aircraft started its journey from Shekou Cruise Homeport in Shenzhen to Jiuzhou Port in Zhuhai, completing the 55-kilometre trip in about 20 minutes. This flight marks an important development of this exciting new form of transport.
EVTOL aircraft use high technology to take off and land straight up and down like a helicopter(直升机), which doesn't need long runways. Instead of using combustion engines, these air taxis use electric motors(电动机). They also have special fans called propellers(螺旋桨) all over their bodies to help them stay balanced in the air. In addition, lithium-ion batteries(锂电池) are used to store electricity, letting them fly far and fast.
Some air taxis, like the EH216-S from China's Ehang, can fly without a pilot. They are controlled by a central command centre that keeps an eye on the flight, the route and the weather.
There is no doubt that air taxis can help improve heavy traffic. They travel point to point, saving time for people who work in the city but live far away. As an eco-friendly choice, air taxis produce fewer emissions(排放) than oil-powered cars, improving city air quality. What's more, air taxis require less space for take-off and landing. That is to say, it can help cities use their space better and save money on building big airports.
However, eVTOL aircraft also require special places to take off and land, which means they need eVTOL airports called "vertiports". Now researchers are trying to make full use of the present small airfields to serve as "vertiports". And with plans to fly at low heights in cities, there's still much work to be done to keep everyone safe.
