能的高壓壓氣機(jī)。
總之 ,為了進(jìn)一步提高中國(guó)高性能大涵道比風(fēng)扇/高壓壓氣機(jī)的研制能力 ,不僅需要加強(qiáng)軟件開發(fā) ,提高軟件精度 ,更應(yīng)提高試驗(yàn)研究水平 ,提高測(cè)試精度 ,提高理論、計(jì)算與試驗(yàn)相結(jié)合的綜合研究分析能力。
4 結(jié) 論
大涵道比渦扇發(fā)動(dòng)機(jī)以其高循環(huán)參數(shù)、低耗油率、低污染、低噪聲、高可靠性和長(zhǎng)壽命等顯著特點(diǎn) ,代表了一個(gè)國(guó)家民用航空發(fā)動(dòng)機(jī)技術(shù)的最高水平 ,也是一個(gè)國(guó)家科技水平和創(chuàng)新能力的重要標(biāo)志。
大飛機(jī)的立項(xiàng) ,使我們面臨著嚴(yán)峻的挑戰(zhàn) ,也帶來(lái)了前所未有的良好發(fā)展機(jī)遇。作者相信 ,統(tǒng)一規(guī)劃 ,精心組織 ,抓住契機(jī) ,迎頭趕上 ,就能盡快趕上國(guó)際先進(jìn)水平。
