1756-ENBT就在中國自主研制的首款大型客機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MRJ在名古屋首飛成功。短短10天之內(nèi),東亞兩個主要國家,分別展示了自己在“大飛機”道路上的新成就。
1756-ENBT綜合外媒消息,在世界大飛機棋局上,中日兩國同為后來者。戰(zhàn)后以來,中日兩國均在民機方面有所嘗試。近年來,兩國則在同期啟動了大飛機工程,但步伐卻明顯不同:中國的首款自主研發(fā)噴氣式支線客機ARJ21已于2008年試飛,今年年底前首架ARJ21將投入實際運營,而載客數(shù)達到ARJ21兩倍以上的C919已經(jīng)下線;日本的MRJ基本與ARJ21處于同一個量級,但卻遲至近日方才首飛,150座級干線客機項目尚未提上議事日程。從進度上看,中國暫時領(lǐng)先日本一步。
同期起跑,中方領(lǐng)先
1756-ENBT此前,中日兩國都在民機方面有所嘗試:20世紀70年代至80年代,中國在借鑒國外技術(shù)的基礎(chǔ)上,自主研制了“運十”大型客機,但最終僅停留于測試階段,未能投入商業(yè)運營;日本則于20世紀60年代研制了60座客機YS-11,并投入批量商業(yè)運行,總產(chǎn)量達到182架。但是,這型客機采用渦輪螺旋槳動力,并非噴氣式客機。
1756-ENBT本世紀之初,中日兩國幾乎同時啟動了支線客機項目。2002年4月,中國國務(wù)院批準(zhǔn)70座客機ARJ21項目立項;同年8月,日本經(jīng)濟產(chǎn)業(yè)省提出了50座支線客機計劃,三菱重工于2003年承接了這一項目,于是就有了MRJ(三菱支線噴氣機,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客機立項后,由當(dāng)時的中航工業(yè)一集團承擔(dān)研制任務(wù),并很快由設(shè)計階段進入工程制造,最終于2008年實現(xiàn)首飛。
