国产客机C919将首飞:突破技术封锁真正属于中国

综合各方面因素,国产大型客机C919将于5月5日在上海浦东国际机场首飞。如天气条件不具备,则顺延。这是中国首次按照国际标准研制、拥有自主知识产权的大型客机,这架被冠之以“全民网红”的飞机今天将吸引全世界的目光,我们来给你详细讲讲它!

三分钟认识中国大飞机C919

外形:小干线家族中的“大块头”

C919为双发涡扇中型机,毕竟是干线客机,长38.9米,连翼展35.8米,高12米,就算身高1米9的乘客走在机舱里也不会觉得不适,最大起飞重量为72吨,虽然没有波音777那么大,但已经是小干线家族中比较大的机型了,最大可容纳190人之多。

C919机身线条流畅,值得一提的是,飞机的机体从设计、计算、试验、制造全是中国自己做的,强有力地回应了对飞机制造自主性的诸多质疑。

飞机采用了新一代超临界机翼,自主发展“一分钟”快速成型的方法提高了机翼曲面的质量,改善跨音速范围内的可控性,减少飞行阻力从而节省了很多燃料。

为了全面认证C919的气动设计,满足对CFD技术的不同精度和效率的要求,不同构型、雷诺数的全、半膜的风洞测试不断开展,包括测力、测压、动力影响,增升装置设计方案选型、验证、确认等一系列超过15000的风洞“吹风”试验,从而拥有了比现役同类飞机更好的巡航气动效率。

再看看它的造型,就是霸气,像是戴着一副俊酷的墨镜。相比需要6块挡风玻璃的传统飞机,C919只有4块,机头更具流线型,使得飞行员视野更开阔,减少阻力。

但是这种挡风玻璃工艺更复杂,制造难度也大。这也使得C919独特到只看脸就可以辨认出来。

由于飞机重量比较重,其发动机甚至比现役的波音737的都要大,所以C919采用了第三代铝锂合金材料,锂元素的加入使其比同等机型轻了5%-10%。飞机上使用的复合材料主要是碳纤维增强树脂基复合材料,具有高耐腐蚀、质量轻等特点,但价格大约是常规铝合金材料的几十倍,所以在机体结构用量只占到了12%。

发动机:技术创新 运营成本降低

航空发动机作为“航空之花”,可以说是航空技术和工业积累的完整体验。C919的发动机为LEAP-X1C发动机。

LEAP-X1C型发动机是由国际公司美国通用电气与法国SNECMA各以50%资金比例合资建立的大型客机发动机生产商CFM国际公司研制的大型喷气客机发动机。它采用了18片赛峰公司研制的碳纤维复合材料风扇叶片以及美国通用电气公司研制的陶瓷基复合材料涡轮部件。

它采用了许多行业内领先的创新性技术,包括超高压比核心机、采用三维编织树脂模传递成型技术制造的复合材料风扇叶片、复合材料风扇机匣、第三代三维气动设计压气机和涡轮叶片设计技术、第二代双环预混旋流器(TAPS II)燃烧室技术、可变面积外涵喷管和先进材料等。发动机和短舱将作为一体化推进系统来设计,拥有先进的进气道、声学处理和电动反推力装置,可以充分发挥其气动性能、重量和声学优势。

这款先进的新型涡扇发动机较CFM之前生产的波音737的发动机有了许多先进性提升。LEAP-X1C发动机燃油消耗可减少16%,二氧化碳排放量可减少16%,氮氧化物排放量可减少至不足60%,且更为安静。

相比于其他发动机,LEAP-X运营成本可以比其他发动机降低15%,这是一项巨大的优势,这也是最终选定LEAP-X系列发动机作为动力装置的最重要原因。
