对标波音787 即将上马的C929才是真正大飞机

2017-05-20 16:44:15   东方网

C929究竟是什么样的飞机?

我们习惯把C919称为“国产大飞机”,但其实它的学名叫“中短程双发窄体民用运输机”,基本座级155座,最大航程5555公里。C919还只是单通道飞机,在如今飞机越造越大,尤其是A380那样的巨无霸问世后,严格意义上,一般双通道、载客300人左右的飞机才被称为“大飞机”。

C929,将是真正意义上的“大飞机”。C929中俄远程宽体客机采用双通道客舱布局,基本型航程为12000公里,座级280座。C929还将采用更为先进的气动设计、大量应用复合材料、装配新一代大涵道比涡扇发动机等提高飞机综合性能指标。从目前透露的数据信息和去年展出的模型看,C929对标的机型应该是波音787飞机。从飞机大小来看,波音787和计划中的C929都不属于“最大号”的客机,但其适用范围更广、经济性更强。

C929需要多久才能问世?

ARJ21从立项到首飞,用了6年,到交付用户正式商用又花了8年,前后总共历时14年。第一步的迈出,总是充满艰辛;

C919从立项到首飞,用了10年,从支线飞机到干线大型客机,跨越非常大。不过业内专家指出,有了ARJ21积累的适航取证经验,预计C919后续取证进程会更顺利一些;
