1947年10月14日,美国试飞员查尔斯·耶格尔驾驶X-1型火箭飞机创造了水平飞行1260公里/小时(1.051马赫)的飞行速度世界纪录。一年后,耶格尔再次驾驶X-1创造了1556公里/小时新的速度世界纪录。为此,世界传媒正式宣告:“航空工业开始步入超音速的时代。”其实,在耶格尔驾驶X-1型火箭飞机创造超音速世界纪录之前,航空强国早已研制了喷气式飞机,并用这些喷气式飞机创造了一个又一个的飞行速度世界纪录。
On October 14, 1947, American test pilot Charles Yeager piloted the X-1 rocket plane to create a world record of 1260 km / h (1.051 Mach) flight speed. A year later, Yeager once again driving the X-1 created a new world record of 1556 km / h speed. To this end, the world media formally declared: “The aviation industry started to enter the supersonic era.” In fact, before Yeager drove the X-1 rocket plane to create a supersonic world record, the aviation powerhouse has already developed a jet aircraft And used these jets to create world-record speed after world.
