日本電氣公司(NEC)今日在東京一個郊區為一款飛天車進行試飛,它的外形像大型無人機,有4個螺旋槳,盤旋了大約1分鐘。

試飛的飛天車高度達3米(10呎),為安全計,試飛在一個大籠內進行。飛天車全長3.7公尺、寛3公尺、高1.5公尺,可搭乘兩人,最大承重量400公斤。飛行原理與大型無人機類似,以四具同軸反轉螺旋槳的舉升風扇提供升力,以電動馬達驅動垂直起飛,不過它也能在地上奔馳,機上安裝前一後二的的車輪。

ABIKO, Chiba (AP) — NEC Corp. on Monday displayed a “flying car,” a large dronelike machine with four propellers that hovered steadily for about a minute.

The test flight, reaching 3 meters high off the ground, was held in a gigantic cage as a safety precaution, at an NEC facility in Abiko, Chiba Prefecture. The preparations, such as the repeated checks on the machine and warnings to reporters to wear helmets, took up more time than the two brief demonstrations.

The government is behind flying cars, with the goal of having people zipping around in them by the 2030s.

Among the government-backed endeavors is a huge test course for flying cars that’s built in an area devastated by the 2011 tsunami, quake and nuclear disasters in Fukushima Prefecture. Mie Prefecture, which is frequently used as a resort area by Hollywood celebrities, also hopes to use flying cars to connect its various islands.

Similar projects are popping up around the world, such as Uber Air of the United States.

其實呢類四軸機好危險,一但無咗動力,就係一個無法控制嘅自由落體。
飛機失去動力,都仲可以有一定控制能力;就算直升機,都有Autorotation呢種無動力狀態下嘅控制能力。
