1756-ENBT就在中國(guó)自主研制的首款大型客機(jī)C919正式下線之后9天,日本首款自行研制的噴氣式支線客機(jī)MRJ在名古屋首飛成功。短短10天之內(nèi),東亞兩個(gè)主要國(guó)家,分別展示了自己在“大飛機(jī)”道路上的新成就。
1756-ENBT綜合外媒消息,在世界大飛機(jī)棋局上,中日兩國(guó)同為后來(lái)者。戰(zhàn)后以來(lái),中日兩國(guó)均在民機(jī)方面有所嘗試。近年來(lái),兩國(guó)則在同期啟動(dòng)了大飛機(jī)工程,但步伐卻明顯不同:中國(guó)的首款自主研發(fā)噴氣式支線客機(jī)ARJ21已于2008年試飛,今年年底前首架ARJ21將投入實(shí)際運(yùn)營(yíng),而載客數(shù)達(dá)到ARJ21兩倍以上的C919已經(jīng)下線;日本的MRJ基本與ARJ21處于同一個(gè)量級(jí),但卻遲至近日方才首飛,150座級(jí)干線客機(jī)項(xiàng)目尚未提上議事日程。從進(jìn)度上看,中國(guó)暫時(shí)領(lǐng)先日本一步。
同期起跑,中方領(lǐng)先
1756-ENBT此前,中日兩國(guó)都在民機(jī)方面有所嘗試:20世紀(jì)70年代至80年代,中國(guó)在借鑒國(guó)外技術(shù)的基礎(chǔ)上,自主研制了“運(yùn)十”大型客機(jī),但最終僅停留于測(cè)試階段,未能投入商業(yè)運(yùn)營(yíng);日本則于20世紀(jì)60年代研制了60座客機(jī)YS-11,并投入批量商業(yè)運(yùn)行,總產(chǎn)量達(dá)到182架。但是,這型客機(jī)采用渦輪螺旋槳?jiǎng)恿,并非噴氣式客機(jī)。
1756-ENBT本世紀(jì)之初,中日兩國(guó)幾乎同時(shí)啟動(dòng)了支線客機(jī)項(xiàng)目。2002年4月,中國(guó)國(guó)務(wù)院批準(zhǔn)70座客機(jī)ARJ21項(xiàng)目立項(xiàng);同年8月,日本經(jīng)濟(jì)產(chǎn)業(yè)省提出了50座支線客機(jī)計(jì)劃,三菱重工于2003年承接了這一項(xiàng)目,于是就有了MRJ(三菱支線噴氣機(jī),Mitsubishi Regional Jet)的名稱。
但是,在隨后的道路上,中日雙方的步伐卻迅速拉開差距:
ARJ21客機(jī)立項(xiàng)后,由當(dāng)時(shí)的中航工業(yè)一集團(tuán)承擔(dān)研制任務(wù),并很快由設(shè)計(jì)階段進(jìn)入工程制造,最終于2008年實(shí)現(xiàn)首飛。
