20年前的9月26日,一架大型喷气式客机在上海大场机场一跃而起,直向蓝天飞去。这就是我国首架自行设计、自行制造的大型远程喷气式客机运十进行首次试飞的情景。至今,仍令人难以忘怀(请参看本期插页)。运十飞机是由上海飞机研究所和上海飞机制造厂研制的四发远程喷气式客机。最早提出的设计方案是在1970年8月,当时的要求仅仅是在轰六飞机的基础上作局部更改,设计航程为5000公里。1971年4月,军委国防工业领导部门又重新下达了研制运十的任务,
Twenty years ago, on September 26, a large jet airliner jumped up at the Shanghai Airport and went straight to the Blue Sky. This is the first time that China’s first large-scale long-haul jet airliner designed and manufactured by itself was flying for the first time. So far, it is still unforgettable (see this insert). Ten transport aircraft by the Shanghai Aircraft Research Institute and the Shanghai Aircraft Manufacturing Company developed four long-range jetliner. The earliest proposed design was in August 1970 when the requirements were only partially modified on the basis of the H-6 aircraft with a designed voyage of 5,000 km. In April 1971, the leading department of the national defense industry of the CMC again issued the task of developing and transporting ten ships,
