在西方工业发达国家,城市交通堵塞和拥挤问题日益严重。针对这个问题,美国莫勒国际制造公司最近研制出一种飞行汽车的样车。这种被命名为“汽车飞机”的飞行汽车型号为 M400。M400有8个发动机,能垂直起降,公路行驶时速为100km,在空中飞行一般时速为320km,最大时速达660km,飞行高度为1500～3000m。M400飞行汽车现正在办理美国航空管理局的有关审批手续,预计明年开始 In western industrialized countries, urban traffic congestion and congestion are worsening. In response to this problem, the United States Moller International Manufacturing Company recently developed a prototype of a flying car. This is called the “car plane” flying car model M400. M400 has eight engines, can take off and land vertically, the highway speed of 100km, the average speed of 320km in the air, the maximum speed of 660km, the flight height of 1500 ~ 3000m.
