                                        2015-12-02 0

                                        國產大飛機后機身開始靜壓與疲勞試驗

                                        C919飛機后機身部段試驗件于4月28日運抵中航工業強度所。后機身部段試驗件是C919飛機項目首次進入強度所的首項大部段試驗件,將進行后機身段與壓力球面單框的靜力和疲勞試驗,在強度所開展C919飛機項目試驗中具有里程碑的作用.

                                        據了解,C919大型客機是我國擁有自主知識產權的中短程商用干線飛機,可載156名至168名乘客。后機身部段后段是C919大型客機七大部段之一,它的主體采用先進的復合材料代替金屬材料,可滿足大型客機自重輕、強度大、抗腐蝕、抗疲勞等要求。該部段試驗是C919飛機七大部段試驗中最大最復雜的一項強度試驗,標志著C919飛機預發展階段試驗進入關鍵階段。
